For my iOS App using Cordova 2.9, I got a error message from the linker when I try to build the Archive:</div>
<div>
<br /></div>
<div>
<span style="background-color: yellow;">file not found: .... libCordova.a</span></div>
<div>
<br /></div>
<div>
<span style="background-color: white; font-family: Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif; font-size: 14px; line-height: 18px;">I found a number of answers at Google, where the solution was to delete armv6, and then the archive would work. Of course, armv6 is gone but the linker error still remains.</span></div>

Obwohl die Entwicklung der Technologie bereits ihre Anfänge in 2002 hatte, steckt ihre Verbreitung bisher noch in den Startlöchern. Die immer größer werdende Anzahl von NFC-fähigen Geräten - insbesondere Smartphones -, die vielfältigen Einsatzmöglichkeiten und die einfache Handhabung machen diese Technologie jedoch zunehmend interessanter für kommerzielle Anwendungen.</p> <h3>Etwas Historie</h3> <p>Die NFC Technologie basiert auf die bereits im zweiten Weltkrieg eingesetzte RFID-Technologie (<i>radio-frequency identification)</i>. Hier wurden Transponder und Lesegeräte an Panzern und Flugzeugen eingesetzt, um fremde von eigenen Fahrzeugen unterscheiden zu können. In den 70igern gab es dann die ersten Systeme zur Sicherung von Waren auf RFID-Chip Basis. Ab 1990 wurden große Fortschritte in der technologischen Entwicklung von Transpondern erzielt, sodass immer mehr Anwendungen entwickelt wurden. Darunter zählen Zugangskontrollen zu Gebäuden, die Wegfahrsperre in Autos, Mautsysteme oder die Zeiterfassungen in Betrieben und die Zeitmessung bei Sportveranstaltungen. <p>NFC wurde im Jahre 2002 durch die beiden Firmen NXP Semiconductors und Sony entwickelt, die führend im Bereich von kontaktlosen Chipkarten sind. Zwei Jahre später wurde durch diese beiden Firmen und Nokia das <a href="http://www.nfc-forum.org/home/">NFC Forum</a> gegründet. Dieses hat es sich zur Aufgabe gemacht, die Entwicklung von NFC voranzutreiben und weiter zu standardisieren. Die ersten NFC-fähigen Handys gab es bereits 2005, mit denen ein Feldversuch in Frankreich durchgeführt wurde. Hier konnten Benutzer Waren im Einzelhandel bezahlen, Parktickets kaufen oder touristische Informationen abrufen. In Deutschland wurde ebenso 2005 ein Feldversuch für den Personennahverkehr vom Rhein-Main-Verkehrsverbund (RMV) gestartet, bei dem Fahrscheine über ein Handy gekauft werden konnten. <p> <h3>Wo wird NFC genutzt?</h3> <p>Bisher kommt diese Technik vor allem in Lösungen für das Micropayment - bargeldlose Zahlungen kleiner Beträge – zum Einsatz. In Deutschland wird die Technik beispielsweise von den Sparkassen, unter dem Namen <a href="http://de.wikipedia.org/wiki/Girogo"><i>girogo</i></a> zur Zahlung von Summen bis zu 20 Euro angeboten. Des Weiteren bietet die Deutsche Bahn mit dem <a href="http://www.touchandtravel.de/">Touch & Travel-System</a> ein sehr einfaches Verfahren zum Erwerben von Fahrtickets mit NFC-fähigen Smartphones, welches für alle Fernverkehrs-, einigen Auslandsverbindungen und in ausgewählten Städten und Regionen verfügbar ist. <p>Ein weiteres Anwendung Szenario sind intelligente Plakate, denen zusätzliche technische Informationen hinzugefügt wurden. Dies geschieht heute noch in der Regel mit QR-Codes, kann aber mittels NFC-Technologie um weitere Möglichkeiten, wie die Übertragung von Texten in mehreren Sprachen, Bilder und Aktionen erweitert werden. Darüber hinaus bieten NFC Tags hier einen besseren Schutz gegen „Edding Attacken“ die dann QR Codes unlesbar machen. Noch im Versuchsstadium befindet sich aktuell die Idee einiger Automobilhersteller (Hyundai, BMW), mit Hilfe des Smartphones und NFC-Funktionen die Autotür zu entriegeln und persönliche Einstellungen der Komfortoptionen im Automobil (Sitz- und Spiegelpositionen, Senderwahl) zu aktivieren. <p>Dies sind an dieser Stelle nur ein paar Anwendungsfälle. In Zukunft werden diese, durch die weitere Verbreitung der NFC Technologie, sicherlich noch zunehmen. <p>Aktuell unterstützen u.a. Geräte von Nokia, Samsung, Blackberry, Google, HTC, LG, Motorola und Sony die NFC Verfahren. Nachlegen wird hier sicher auch bald Apple, da das aktuelle iPhone 5 die NFC-Technologie noch nicht beinhaltet. Neben vielen aktuellen Smartphones sind auch einige Tablet-PCs mit eingebauter NFC-Technik verfügbar. </p> <h3>NFC Kommunikationswege</h3> <p>NFC setzt auf induktiv gekoppelte Systeme, bei denen passive Transponder die Energie aus einem Magnetfeld ziehen. Da jedoch bei NFC, im Gegensatz zu RFID, die strikte Trennung zwischen Lesegerät und Transponder entfällt, ergeben sich einige neue zusätzliche Kommunikationsmöglichkeiten. Für diese unterschiedlichen Kombinationen von Komponenten sind verschiedene Übertragungsmodi vom NFC Forum definiert worden. <p>So ermöglicht der <i>Reader/Writer-Modus</i> die Kommunikation zwischen einem NFC-Gerät und einem passiven Transponder. Im <i>Peer-to-Peer</i>-Modus können zwei NFC-Geräte Daten untereinander austauschen (z.B. bei Windows Phone Tap & Senden). Der <i>Card-Emulation-Modus</i> ermöglicht dem NFC-Gerät als Smartcard zu agieren und als passiver Teilnehmer mit einem normalen RFID basierenden Lesegerät zu kommunizieren. <p> <h3>Was braucht man alles um mit der NFC Entwicklung loszulegen? </h3> <p>Zur Entwicklung von NFC Anwendungen für Windows Phone benötigen wir Visual Studio 2012, das Windows Phone SDK und ein Windows Phone 8 (z.B. Nokia Lumia 920). Man braucht ein echtes Gerät, da vom aktuellen Windows Phone Emulator NFC leider noch nicht unterstützt wird. Als weitere Software-Komponente benötigt man die <a href="http://ndef.codeplex.com/">NDEF Library for Proximity APIS</a>, da die native Windows Phone API keine NDEF Nachrichten schreiben kann. Es ist auch möglich, die NDEF Library via Nuget mit dem Kommando <i>Install-Package NdefLibrary </i>zu installieren. <p>Als weiteres benötigen wir natürlich noch brauchbare NFC Tags, welches sich bei mir als ein sehr schwieriges Unterfangen herausgestellt hat. Es waren zwei Bestellversuche notwendig, um geeignete NFC Tags zu erhalten. Wichtig ist nämlich hierbei, dass man keine leeren NFC Tags verwendet, sondern NFC Tags, welche mit dem <a href="http://www.developer.nokia.com/Community/Wiki/Understanding_NFC_Data_Exchange_Format_(NDEF)_messages">NDEF (<i>NFC Data Exchange Format</i>) Format</a> beschrieben bzw. formatiert wurden. Aktuell bietet uns die Windows Phone Proximity Api keine Möglichkeit NFC Tags zu formatieren. Ein NFC Tag kann in verschiedenen Ausprägungen – als Armband, Schlüsselanhänger oder Papier Sticker – bezogen werden. Einfach NFC Tags in eine Suchmaschine seiner Wahl eingeben und einen geeigneten Shop suchen. <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhqOH-D5mNVM1wpNgbNuEt1q_pjjdZ_ULDZ_FwxSuJ2dDLcnKWafci-aeKcw-JaWBklqhu1rMP_CStptAvZyoaR63UlU4yQAEE96MgftFohP1occN8uGr7X4gbQ2FtCn_kt8HFLzU5J8kg/s1600-h/clip_image002%25255B6%25255D.jpg"><img title="Windows Phone NFC" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; display: inline; padding-right: 0px" border="0" alt="Windows Phone NFC" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhgu5lL2FEq9jao1WteTazNHNQCoXG1miadr4F9Wp0MaLGaIiyWBVdsnikNAPiz0f-BNzkvthhI_of9rLxEnS4INa9bFpOUWUk_0cI_5cvEjsTWWyCrlugRoy1UHYgilmc8jNLaIS1gT48/?imgmax=800" width="337" height="201"></a> <p>Ein NFC Tag kann durch das Windows Phone mit unterschiedlichen Informationen im NDEF Format beschrieben werden. Die Größe der aktuellen Tags reicht von 168 Byte, über einem bis zu maximal vier Kilo Byte. <p>Unterstützt werden von Windows Phone folgende NFC Tags: <ul> <li>Type 1: Topaz family <li>Type 2: Mifare Ultralight family, my-d-move, NTag <li>Type 3: Felica family <li>Type 4: Desfire family <li>Non standardized: Mifare Standard </li></ul> <h3> </h3> <h3>Einige Einschränkungen</h3> <p>Aktuell müssen wir beim Umgang mit NFC Tags mit einigen Einschränkungen leben, die die Arbeit mit NFC Tags eigentlich nicht beschneiden, sondern lediglich einige Anwendungsszenarien beschränken. <ul> <li>Es ist durch die fehlende Unterstützung des RAW Modus bei Windows Phone nicht möglich, den Schreibschutz eines NFC Tags zu aktivieren. <li>Mittels Windows Phone können keine NFC Tags formatiert werden – also nur vorformatierte oder beschriebene Tags im NDEF Format kaufen. Eine weitere Alternative ist die Verwendung eines NFC USB Reader/Writer oder – ich wage es kaum zu erwähnen – die Benutzung eines Android Geräts. <li>Der NFC Tag darf nur NDEF Nachrichten enthalten, damit er lesbar bleibt. <li>Es ist nicht möglich, den kompletten Speicherplatz eines NFC Tags zu benutzen. Beispielsweise können nur 716 Bytes bei einem 1KB Tag oder 454 Bytes bei einem Tag mit einer Größe von 512 Byte genutzt werden <li>Die Proximity API von Windows Phone bietet keine Möglichkeit direkt NDEF Nachrichten auf den Tag zu schreiben. Dies ist aber durch die Benutzung der Open Source <a href="http://ndef.codeplex.com/">NDEF Library</a> möglich, die ich in meinem Beispiel auch verwendet habe <li>Es ist nicht möglich die Daten eines NFC Tags zu empfangen oder zu schreiben, wenn die Windows Phone App im Hintergrund läuft. Man kann aber über Schemata-Zuordnungen und die Auto-Launch Funktion – dazu später mehr - eine im Hintergrund oder noch nicht laufende Applikation starten</li></ul> <h3> </h3> <h3>Der Schüssel zu allem: Windows.Networking.Proximity</h3> <p>Im Namensbereich <font face="Courier New">Windows.Networking.Proximity</font> befindet sich der Einstiegspunkt der <a href="http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj207060(v=vs.105).aspx#BKMK_ProximityAPI">Proximity API</a> von Windows Phone. Die wichtigste Klasse ist hierbei <em>ProximityDevice</em>. <p> <h3>Der Use Case - Check-in mit NFC Tags</h3> <p>Innerhalb der SDX AG nutzen wir eine neue eigenentwickelte Zeiterfassungs-Software mit der Bezeichnung WorkTime. Dieses System basiert auf dem Microsoft CRM System und ist als Client für Windows 8 (Modern UI App), Windows Phone 8 sowie als Web-Anwendung verfügbar. Also warum sich nicht die NFC Tags zu Nutze machen und die lästige Zeiterfassung bei unterschiedlichen Projekten dadurch verkürzen, das ein NFC Tag die projektspezifischen Daten zu einem Zeiterfassungsvorgang bereits enthält und durch das „Tappen“ mit dem Windows Phone ein Zeiterfassungsvorgang automatisiert vorgenommen werden kann. Ich hätte dann für unterschiedliche Kunden und Projekte jeweils einen anderen farblich gekennzeichneten Tag und könnte diese sogar am entsprechenden Arbeitsplatz irgendwo hin kleben. </p> <p>Also Idee in die Tat umsetzen…</p> <h3>Erster Schritt – Speichern der Daten auf dem NFC Tag</h3> <p>Das folgende Code Schnipsel verwende ich, um den serialisierten aktuellen Zeiteintrag auf einem NFC Tag zu speichern. Wichtige Einstiegspunkte sind hierbei die Events <i>DeviceArrived</i> und <i>DeviceDeparted</i>, welche entsprechend geworfen werden, sobald sich ein NFC Tag in der Nähe des Windows Phone befindet oder sich wieder entfernt hat. Im Konstruktor meiner NfcService Klasse ermittele ich mir dazu zunächst das aktuelle Proximity Device über die <i>ProximityDevice.GetDefault()</i> Methode. <p>Zum Zugriff auf den NFC Tag verwende ich in meinem Beispiel, wie gesagt, die <a href="http://ndef.codeplex.com/">NDEF Library</a> welche es auf einfache Art und Weise ermöglicht NDEF Datensätze zu parsen sowie diese zu erstellen. Ein NFC Tag kann dabei immer einen oder mehrere NDEF Datensätze enthalten. Die NDEF Library unterstützt verschiedene Datensatz Typen, wie beispielsweise <i>WpSettings</i> (zum Starten von Windows Phone Einstellungsseiten), <i>Mailto</i> (Datensätze zum automatischen Versenden von E-Mails), <i>DriveTo</i> und <i>WalkTo</i> (Starten der Navigationsfunktionen von Windows Phone 8), <i>Nokia Accessories</i> (Datensatz zum Starten von Nokia Zusatzanwendungen auf Lumia Smartphones) und der wichtige <i>Launch App Record</i> zum automatischen Start einer Windows Phone App. Dieses NDEF Nachrichtenformat wird auch in folgenden Beispiel verwendet. <p> <div id="codeSnippetWrapper"> <div id="codeSnippet" style="border-top-style: none;

<p>Beim Schreiben auf einen NFC Tag sind folgende Punkt besonders zu beachten:
<ul>
<li>Bei Verwendung eines NdefAppLauchRecord muss als Plattform <i>WindowsPhone</i> und die ProductId der App aus dem AppManifest angegeben werden
<li>Ein Aufruf von <i>_device.StopPublishingMessage</i> nach erfolgtem Schreiben ist notwendig
<li>Die Message Größe des NDEF Records darf nicht die Nettokapazität des NFC Tags überschreiten
<li>Um NFC in der App nutzen zu können, muss <i>ID_CAP_PROXIMITY</i> in den Application Capabilities aktiviert werden</li></ul>
<p>Der Umgang mit den anderen NDEF Nachrichtentypen ist analog zu diesem Beispiel, außer dass hier die Nachricht anders aufgebaut werden muss.
<p>So weit so gut - jetzt können wir die Daten auf einen NFC Tag schreiben. Aber wie schaffe ich es, dass meine App nun automatisch beim „Tappen“ mit meinem Lumia gestartet wird?
<p> <h3>Hinzufügen der Auto-Start Funktionalität</h3>
<p>Um eine Windows Phone 8 automatisch starten zu können, ist es notwendig eine URI Zuordnung für die jeweilige App zu erstellen. Was diese URI auszeichnet, ist das diese mit einem festen Schemanamen beginnt, der für diese App registriert wurde. Nachdem diese Registrierung dem Betriebssystem bekannt gemacht wurde, wird durch das „Tappen“ mit einem NFC Tag, welcher einen LaunchApp NDEF Record enthält, über die ProductId im NDEF Record genau eine solche URI von Windows Phone OS aufgebaut und die App mit dieser URI gestartet.
<p>Die Nutzung von Schema-Zuordnungen zu einer Windows Phone App ist übrigens ein allgemeines Feature und kann beispielsweise auch zum Aufruf einer Windows Phone App über eine URI aus einer anderen App genutzt werden.
<p>Beispiel: <i><font face="Courier New">worktime:ShowTimeSheetEntry?UniqueId=89819279-4fe0-4531-9f57-d633f0949a19</font></i>
<p>In diesem Beispiel ist <i>worktime</i> das registrierte App Schema und alles nach dem Doppelpunkt kann durch die App in der UriMapper Klasse – dazu später mehr – interpretiert werden.
<p>Über den folgenden Code kann die WorkTime App aus einer anderen App aufgerufen werden:
<p><font face="Courier New">Windows.System.Launcher.LaunchUriAsync(new System.Uri("<i>worktime:ShowTimeSheetEntry?UniqueId=89819279-4fe0-4531-9f57-d633f0949a19</i>"));</font>
<p>Um eine URI Verknüpfung für eine App zu erstellen, muss die <i>WMAppManifest.xml</i> Datei des Windows Phone Projekts mit dem XML(Text) Editor bearbeitet werden. Im <i>Extensions</i>-Element der Manifest-Datei wird eine URI-Verknüpfung durch das Hinzufügen eines <i>Protocol</i>-Elements definiert. Bitte beachten, dass das Extensions Element <b>sofort nach dem Tokens-</b>Element eingefügt werden muss. Man kann maximal 10 URI-Verknüpfungen in jeder App definieren. Die Schema-Namen einer App müssen dabei eindeutig bei den installierten Apps sein – also genau überlegen was man hier nimmt.<br>

<p>Einige Schemata sind reserviert und würden bei Verwendung ignoriert werden. Für mehr Informationen, siehe <a href="http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj207065(v=vs.105).aspx">Reservierte Datei und URI Verknüpfungen</a> für Windows Phone 8.
<p>Die generierte URI aus dem NFC Tag LaunchApp Record zum automatischen Starten der WorkTime App sieht dann folgendermaßen aus:
<blockquote>
<p>Protocol?encodedLaunchUri=worktime:<xml string of our TimesheetEntry object></p></blockquote>
<p>Hinter dem Doppelpunkt folgt die XML Repräsentanz der Zeiteintrags-Instanz.
<p> <h3>Extrahieren der Aufrufparameter aus der URI</h3>
<p>Um nun die aufrufende URI aufzulösen, ist die Klasse <i>UriMapper</i> zu implementieren, welche von <i>UriMapperBase</i> abgeleitet ist. Die Argumente der LaunchApp NDEF Nachricht auf unserem Tag müssen dann in dem Parameter <i>ms_nfp_launchargs</i> für den Aufruf der gewünschte Einstiegsseite der Windows Phone App übergeben werden, da dieser Mechanismus auch vom Betriebssystem beispielsweise über eine Sekundärkachel (<i>deep linking</i>) verwendet wird. <br><font size="1">(Niemand weiß, ob <i>ms_nfc_launchargs</i> korrekt ist oder <i>ms_nfp_launchargs</i> weil in der MSDN Dokumentation werden beide erwähnt :-( - aber alle Beispiele funktionieren mit <i>ms_nfp_launchargs</i>)</font>
<p>Die folgende UriMapper Klasse dekodiert zunächst die aufrufende Uri und benutzt dann einen regulären Ausdruck um die Payload der NDEF Nachricht zu extrahieren: </p>

<p>Jetzt wird die aufrufende Uri mit dem Schema der App in eine relative Adresse der gewünschten Aufrufseite (in meinem Fall MainPage.xaml) transformiert und die Payload der NDEF Nachricht wird im Parameter <i>ms_nfp_launchargs </i>übergeben<i>.</i>
<p><em></em> <h3>Parsen der Argumente und Zeiteintrag anlegen</h3>
<p>In meiner MainPage.xaml, oder der jeweiligen Zielseite, müssen nur noch die Übergabeargumente extrahiert und einer entsprechenden Funktion übergeben werden. Im <i>OnNavigateTo</i> Event kann hierzu mittels <i>NavigationContext.QueryString["ms_nfp_launchargs"] </i>der Aufrufparameter, also die Payload des NFC Tags, ausgelesen werden. In meinem Fall handelt es sich, wie bereits erwähnt, um die serialisierte Klasseninstanz eines Zeiteintrags. Durch eine Funktion wird nun auf Basis dieses Zeiteintrags ein neuer Eintrag für den aktuellen Tag angelegt, den ich aus Gründen der besseren Usability noch mal zur Betätigung anzeige.
<p> <h3>Das Ergebnis</h3>
<p>Schreiben eines NFC Tags über die Kontextfunktion aus einem bestehenden Zeiteintrag:

So it is good, if you have your own concrete data from the marketplace statistic to measure the Windows Phone 8 App relevance.As an indicator, I've even used my Windows Phone 8 app NFC Tag Manager. The NFC Tag Manager app has reached a download number of around 1200 in the first month. A number, which I never would have expected. For me so a clear indication that the Windows Phone 8 market is growing. </p> <p>So build now your own Windows Phone 8 app.</p> <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhldKBiDPmLy4EYtX9A0T3953JUSelsQniUz_9x9Z74b0wbLN1zEEziYt5wSlTCIA7kJ2BrB14G-cOi2mOn2f1lZyXki7o6XokN_6RS4HqVZT6G_fi6aZF2fcuJb0YrItZHj4x_TNpOOvA/s1600-h/WindowsPhone8_NFC%25255B4%25255D.png"><img title="Windows Phone 8 NFC" style="border-top: 0px;

You can use this, if you have an unknown NFC tag and want to know which content is on it.</p> <p>Some more NFC functions are coming next.</p> <p><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKFWe3GYz8rcG_w_YiqaJIrms0JciBDNs7nvuUcNvH-cH2-08GBirVmredfHLB2gHtC5tlQH0axKllfhs1rP-hn9LeZzqitTwEtXhNV0UtCgJ4R93le6xKqI5AddmWgLQYI10k5Vjh6RI/s1600-h/Screenshot_WVGA%25255B3%25255D.png"><img title="NFC tag manager" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; display: inline; padding-right: 0px" border="0" alt="NFC tag manager" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiPbzSEs9ZWSiktk76T0aOeVKC1rnC4PJaZkp_gt3bPtkZ1877dSkkRTrHLcOz5CcO5AXnPH6VlqeD391P0qgoCQ9gcQJi9hjlsqOAVN_Ufah4Ggd3mSEa6-pCaKtvLRWjrOzRfIuFPKCU/?imgmax=800" width="224" height="383"></a></p> Patric Schoulerhttp://www.blogger.com/profile/05180837550506566896noreply@blogger.com0tag:blogger.com,1999:blog-3122685766060763329.post-86036578729313395462012-12-30T11:54:00.001+01:002013-01-02T17:29:22.346+01:00Windows Phone 8 NFC usage in WorkTime app<p>As I mentioned in one of my last posts I have ordered some NFC tags to try out the new abilities of Near Field Communication (NFC) for Windows Phone 8 using the <a href="http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj207060(v=vs.105).aspx#BKMK_ProximityAPI">Proximity API</a>. </p> <h3>The user story – Check-in by NFC tag</h3> <p>For my timesheet management application I decided that I want to use NFC technology to register new timesheet entries (check-ins) in a quick and short way. Therefore my application should have a new menu item at the timesheet entry detail page which creates a NDEF auto-launch message at a NFC tag with the current timesheet entry data. So you could have a particular NFC tag for each customer and project. If the user now tapping one of these NFC tags the WorkTime app should be started and a new entry as a clone of the data at the NFC tag should be created.</p> <h3>First step – save data to the NFC tag</h3> <p>The following code snippet I use to store the serialized current timesheet entry at the NFC tag:</p> <div id="codeSnippetWrapper" style="overflow: auto;

<p>I am using the <a href="http://ndef.codeplex.com/">NDEF library</a> which helps me easily parse and create NDEF records with the Windows Proximity APIs (NFC). You can install the NDEF library via Nuget with <em>Install-Package NdefLibrary</em>. The NDEF library supports several record types such as WpSettings (for launching Windows Phone 8 settings pages), Mailto (records for sending email messages), DriveTo and WalkTo (URI schemes for starting navigation on WP8), Nokia Accessories (record to easily launch apps on Nokia Lumia WP8 phones) and the Launch App Record for auto-launching a Windows Phone 8 app.</p>
<p>But what to do at your app to support auto-launching?</p>
<h3>Add Auto-Launching ability</h3>
<p>To auto-launch a Windows Phone 8 app we have to add a URI association (a very nice new feature of Windows Phone 8) for the WorkTime app. What makes that URI special is that it begins with a URI scheme name that your app has registered for. After you do this registration, your app will be automatically started by the Windows Phone operating system, if anyone calls a URI with this scheme or the NFC tag contains a URI with the registered scheme.</p>
<blockquote>
<p>Example: <em>worktime:ShowTimeSheetEntry?UniqueId=89819279-4fe0-4531-9f57-d633f0949a19</em></p></blockquote>
<p>In this sample <em>worktime</em> is the registered app scheme and all after the colon could be interpreted by your app in a UriMapper class (see later).</p>
<p>To register for a URI association, you must edit the <em>WMAppManifest.xml</em> file of your project using the XML (Text) Editor. In the Extensions element of the app manifest file, a URI association is specified with a Protocol element. Note that the Extensions element must <strong>immediately follow the Tokens</strong> element. You can register a maximum of 10 URI associations in each app.</p>

<p>Some schemes are reserved and will be ignored. For more information, see <a href="http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj207065(v=vs.105).aspx">Reserved file and URI associations for Windows Phone 8</a>.</p>
<p>The URI of our NFC tag looks like: </p>
<blockquote>
<p>Protocol?encodedLaunchUri=worktime:<xml string of our TimesheetEntry object></p></blockquote>
<h3>Map the URI and add MainPage arguments</h3>
<p>To resolve the incoming URI we have to implement a UriMapper class which is derived from <em>UriMapperBase</em> and use this as new UriMapper in our application. The arguments from the LaunchApp tag are encoded into the query string. The pre-defined key name for the launch arguments which will be used also by the operating system is <tt>ms_nfp_launchargs </tt></p>
<p><tt><font face="Arial"><font size="2">(<em>nobody knows if ms_nfc_launchargs is correct or ms_nfp_launchargs because in the MSDN documentation they have mentioned both :-( - but all samples working with <tt><font face="Arial">ms_nfp_launchargs</font>)</tt></em></font></font></tt></p>
<p>My UriMapper class decodes the Uri and uses a regular expression to parses the payload of my NDEF message: </p>
<p><tt><font face="Arial"><font size="2"><em><tt></tt></em></font></font></tt></p>

<p>Now the UriMapper will match the incoming Uri from the NFC tag to a relative Uri the MainPage.xaml with the NFC tag arguments as query parameter <em>ms_nfp_launchargs.</em></p>
<h3>Parse arguments and add TimesheetEntry</h3>
<p>At my MainPage.xaml I have now to check the arguments (I use also Voice commands, therefore to check this too) and invoke the correct function of my MainViewModel. To use MVVM I have added a new message of the type NavigationMessage and send this in the NavigateTo event of my MainPage to the Messenger component of MVVMLight.</p>

<h3>Supported NFC tags at Windows Phone 8</h3>
<p>My Lumia 920 – but according the documentation also the rest of Windows 8 Phone - supports the following tag types:
<ul>
<li>Type 1: Topaz family
<li>Type 2: Mifare Ultralight family, my-d-move, NTag
<li>Type 3: Felica family
<li>Type 4: Desfire family
<li>Non standardized: Mifare Standard</li></ul>
<p>Regarding NFC tags NDEF formatting:
<ul>
<li>Windows Phone 8 supports only NDEF level access to these tags, that means that the tag needs to be NDEF formatted or have an existing NDEF message on it (empty or not). If you try to use the APIs on a non-formatted NFC tags they won’t work (as Windows Phone 8 has no support for low level Tag Type specific commands/access)
<li>Tip: If you want to NDEF format your tags you can ordering tags which are already NDEF formatted. Alternatively you can use an NFC USB Reader/Writer for PC or use an Android NFC device with an NFC writing app</li></ul>
<h3> </h3>
<h3>The result - How it’s look like</h3>
<p>In my timesheet detail page I have now a menu entry for a NFC Tag page (create NFC Tag- sorry for the German screenshot) </p>
<p>The NFC status page which writes the data to the NFC tag, if this is tapped. I used the <em>DeviceArrived</em> and <em>DeviceDeparted</em> events of the API (see code above) to inform the user if the tag is in writable near.</p>

To get started I found some very good websites which explains the NFC technology and contains several samples for writing and reading NFC tags.</p> <p>If you plan to work with NFC tags consider the following points. Especially if you order NFC tags, check if they support the NDEF standard and the tags <strong>are already formatted</strong>.</p> <ul> <li>You cannot enable the write lock. <li>You cannot format a tag. Your tag must be formatted for NDEF message. <li>Your tag can contain only an NDEF message. <li>You cannot use all tag memory. NDEF formatting data and other private tag data take memory. Because of the fact that a tag has only a few bytes of memory, this data size is important. For example, you can only write 716 bytes on a tag with a memory of 1024 bytes and 454 bytes on a tag with a memory of 512 bytes. <li>Proximity API does not give tools to manipulate directly NDEF messages. To manipulate raw NDEF messages you can use <a href="http://ndef.codeplex.com/">NDEF Library for Proximity APIs (NFC)</a>. <li>You cannot receive or write a tag when your application runs in background. </li></ul> <p>Detail information about NFC on Windows Phone 8 you could found here:</p> <ul> <li><a title="http://www.developer.nokia.com/Community/Wiki/Use_NFC_tags_with_Windows_Phone_8" href="http://www.developer.nokia.com/Community/Wiki/Use_NFC_tags_with_Windows_Phone_8">Entry page for using NFC tags with Windows Phone 8 on Nokia developer Wiki</a></li> <li><a title="Microsoft documentation of the Proximity API" href="http://msdn.microsoft.com/library/windowsphone/develop/windows.networking.proximity.aspx">Microsoft documentation about the Proximity API</a></li> <li>C<a title="Common page of the Nokia developer Wiki about NFC technology" href="http://www.developer.nokia.com/Community/Wiki/Category:Near_Field_Communication_(NFC)">ommon page of the Nokia developer Wiki about NFC technology</a></li> <li><a href="http://www.nfcinteractor.com/developers/nfc-developer-comparison/">Comparison about supported NFC technologies on the different platforms</a> – NFC support on Windows Phone 8</li> <li><a title="https://ndef.codeplex.com/" href="https://ndef.codeplex.com/">NDEF Open source library to read and write NDEF formatted NFC messages on Windows Phone 8</a></li></ul> Patric Schoulerhttp://www.blogger.com/profile/05180837550506566896noreply@blogger.com2tag:blogger.com,1999:blog-3122685766060763329.post-41740763931717931672012-12-22T12:18:00.001+01:002012-12-22T12:18:58.481+01:00Windows Phone 8 Why no official calendar control?<p>Last night I have tried several calendar controls for my Windows Phone 8 time sheet app, but no one matches my requirements and looks like the core calendar of Windows Phone 8.

Therefore I searched for my current project – a Windows Phone 8 app to manage time sheets - a good solution to implement validation rules for my entities at a central point in my models. I found a nice implementation of a <em>BindingModel</em> from <a href="http://www.codeproject.com/Members/outcoldman">outcoldman</a> at <a href="http://www.codeproject.com/Articles/134937/Silverlight-basics-Validation">Codeproject</a>. He looks at several validation technologies we have with Silverlight and describes them in the mentioned article in detail. Most of my classes based on this article which I have expanded by some new behaviors and properties. <p>My resulting validation code in the constructor of my models looks like this: <p> <div id="codeSnippetWrapper"> <div id="codeSnippet" style="border-top-style: none;

<h3> </h3>
<h3><br>The basics</h3>
<p>The <a href="http://msdn.microsoft.com/en-us/library/system.componentmodel.inotifydataerrorinfo(VS.95).aspx"><code>INotifyDataErrorInfo</code></a> interface came with Silverlight 4 which can be used for synchronous and asynchronous validation. Microsoft suggestion is, that new entity classes should implement INotifyDataErrorInfo for the added flexibility instead of implementing <a href="http://msdn.microsoft.com/en-us/library/system.componentmodel.idataerrorinfo(v=vs.95).aspx">IDataErrorInfo</a>. The <a href="http://msdn.microsoft.com/en-us/library/system.componentmodel.idataerrorinfo(v=vs.95).aspx">IDataErrorInfo</a> support enables you to use many existing entity classes that are written for the full .NET Framework.
<p> <h3>Let’s start</h3>
<p>The first step of the validation rule implementation is to expand our properties for storing validation rules and manage error messages.This is done by the <em>PropertyValidation</em> class:</p>

<p>But how to show a list of the error messages for the corresponding fields?</p>
<p>To achieve this, I made a converter (our swiss knife :-) which extracts the error messages from the ErrorMessages property and populate that to a user control which shows the error list for one property (the parameter of the converter contains the bounded property name for which I want to display the error messages).</p>

Therefore the sharing of the data access classes is for example possible via linking the same code classes in separates data layer libraries:</p> <p> <a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiLBI06oQ7Znjt_CAhn8LB8YZi5vh9F4cT7UfPrIvrazYVClVNWQVPuiXnp1tCgORXOSDSt_9Qkv2M1l4gWAJvFjcBgny9JtgFQ6pf8aiBEkII4iIKYWj1kyzEa7T0FxesOaZYvN_xLqaI/s1600-h/image%25255B3%25255D.png"><img title="image" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; display: inline; padding-right: 0px" border="0" alt="image" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgyuNj_S8QgkxpjXN2rS-bpTDs_YWIvt4U4nQQrkU0UOP-Re3cZ4ZhyaEtcfOJ6Kx8-WO4wxOJtxkcBWlBr3vavJMKfgMN1vSTrjmsWiGpqEiy-0ErTcKtXlwYUgPWUCrB3wG9EHJkBO8k/?imgmax=800" width="348" height="361"></a></p> <p>To capsulate the data classes, which is possible by using the new portable library type in Visual Studio, you have to use a little “dirty” trick. If you install <strong>sqlite-net</strong> via Nuget you got two classes <em>SQLite.cs</em> and <em>SQLiteAsync.cs</em> for asynchronous database access. In the class <em>SQLite.cs</em> you will find the property attributes for your data classes. If you want to put them in a reusable library, you have to comment the necessary attribute definitions and copy them to your data classes library. Really dirty – but it works .-)</p> <p>So in my portable library I have also a SQLite.cs file with only the primary attribute definition (I need no more) in the SQLite namespace:</p> <div id="codeSnippetWrapper"> <div id="codeSnippet" style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; line-height: 12pt; padding-right: 0px; width: 100%; background-color: #f4f4f4"><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: white"><span style="color: #0000ff">using</span> System;</pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: #f4f4f4"> </pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: white"><span style="color: #0000ff">namespace</span> SQLite</pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: #f4f4f4">{</pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: white"> [AttributeUsage(AttributeTargets.Property)]</pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: #f4f4f4"> <span style="color: #0000ff">public</span> <span style="color: #0000ff">class</span> PrimaryKeyAttribute : Attribute</pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: white"> {</pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: #f4f4f4"> }</pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: white">}</pre><!--CRLF--></div></div>

SQL CE as database engine and LINQ to SQL to manipulate and define tables using classes.</p> <p>(2) At the Build Microsoft introduces a new solution for Windows Phone 8: <strong>SQLite.</strong> That the right decision, because with SQLite you have the chance to share your local application data across several platforms Windows Phone 8, Windows 8, Android and iOS. Microsoft has worked with the SQLite team to provide an easy way to add SQLite to our Windows 8 and Windows Phone 8 projects. The result are two extensions in the <a href="http://visualstudiogallery.msdn.microsoft.com/">Visual Studio Gallery</a>. One to support Windows 8 projects and an other one to use with Windows Phone 8. </p> <h3><strong>Writing native code for Windows Phone 8?</strong></h3> <p>But what his? These extensions are only the SQLite database engine and written <strong>in native code</strong>.To use them you have to write native code to interact with the SQLite database engine and perform operations with the database. So what to do: Searching a library which supports a wrapper that you can use C# to use the SQLite database engine.</p> <p>Peter Torr – who introduces SQLite at the Build - actual posts about the current development process for such an wrapper from Microsoft: <a title="http://blogs.msdn.com/b/ptorr/archive/2012/11/27/update-on-sample-code.aspx" href="http://blogs.msdn.com/b/ptorr/archive/2012/11/27/update-on-sample-code.aspx">http://blogs.msdn.com/b/ptorr/archive/2012/11/27/update-on-sample-code.aspx</a> – so we have to wait for the demoed solution from Microsoft.</p> <p>So Microsoft gives us a new SQLite database engine but <strong>unfortunately </strong>no wrapper library to access this by C#.</p> <h3>What’s about csharp-sqlite?</h3> <p><strong>csharp-sqlite</strong> is published on <a href="http://code.google.com/p/csharp-sqlite/">Google Code</a> that allows to use the native SQLite engine directly in a C# application. I have worked with this library already on Windows Phone 7 and the library works fine with Windows Phone 8 and can be used as it is. </p> <p>But if you want to use the same data access layer within Windows Phone 8 and Windows 8 (which should be the main goal for developing apps for these platforms)? The solution: Usage of a additional library <strong>sqlite-net</strong> which could be found and installed via Nuget:</p> <p id="codeSnippetWrapper"></p> <div id="codeSnippet" style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; line-height: 12pt; padding-right: 0px; width: 100%; background-color: #f4f4f4"><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: white"><span style="color: #0000ff"><?</span><span style="color: #800000">xml</span> <span style="color: #ff0000">version</span><span style="color: #0000ff">="1.0"</span> <span style="color: #ff0000">encoding</span><span style="color: #0000ff">="utf-8"</span>?<span style="color: #0000ff">></span></pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: #f4f4f4"><span style="color: #0000ff"><</span><span style="color: #800000">packages</span><span style="color: #0000ff">></span></pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: white"> <span style="color: #0000ff"><</span><span style="color: #800000">package</span> <span style="color: #ff0000">id</span><span style="color: #0000ff">="sqlite-net"</span> <span style="color: #ff0000">version</span><span style="color: #0000ff">="1.0.5"</span> <span style="color: #ff0000">targetFramework</span><span style="color: #0000ff">="wp80"</span> <span style="color: #0000ff">/></span></pre><!--CRLF--><pre style="border-top-style: none; overflow: visible; font-size: 8pt; border-left-style: none; font-family: 'Courier New', courier, monospace; border-bottom-style: none; color: black; padding-bottom: 0px; direction: ltr; text-align: left; padding-top: 0px; border-right-style: none; padding-left: 0px; margin: 0em; line-height: 12pt; padding-right: 0px; width: 100%; background-color: #f4f4f4"><span style="color: #0000ff"></</span><span style="color: #800000">packages</span><span style="color: #0000ff">></span></pre><!--CRLF--></div><strong></strong>

<p> <p>So in case you are developing a Windows Phone application and you need to use a database, which are the possible solutions?
<p> <h3>What database solutions for Windows Phone 8?</h3>
<p>The first one I mentioned above: still keep using the old SQL CE which works just fine in Windows Phone 8. But then your database could not be used by other apps from different platforms.
<p>A alternative approach is to use SQLIte and the <strong>csharp-sqlite</strong> library. Together with <strong>sqlite-net</strong> you can implement the same data access layer for Windows 8 and Windows Phone 8 by changing the underlying SQLite database engine for both platforms.

With Windows Phone 7 you have to handle with the Bing translation services, but now you have a capsulated API in the <em>Windows.Phone.Speech.Recognition</em> namespace. Here is a sample code which uses the default Dictation grammar for Recognition. It is also possible to define your own grammar (expected words) by code or using a SRGS grammar file.</p> <p>W3C Standard definition: <a title="http://www.w3.org/TR/speech-grammar/" href="http://www.w3.org/TR/speech-grammar/">http://www.w3.org/TR/speech-grammar/</a></p> <p>Microsoft MSDN documentation: <a title="http://msdn.microsoft.com/en-us/library/hh361633(v=office.14).aspx" href="http://msdn.microsoft.com/en-us/library/hh361633(v=office.14).aspx">http://msdn.microsoft.com/en-us/library/hh361633(v=office.14).aspx</a></p> <div id="codeSnippetWrapper" style="overflow: auto;

<p><strong>But there is an issue with the Speech recognition API, if you localize the app title with a C++ resource-only DLL.</strong></p>

<p>If you use this way of localization for your app title you get an error message from the Speech Recognition API “We're sorry, but we can't access the network right now” ?!? (costs me several hours to find out this correlation)</p>
<p>But if you remove the reference to the AppResLib.dll it works properly.</p> Patric Schoulerhttp://www.blogger.com/profile/05180837550506566896noreply@blogger.com0tag:blogger.com,1999:blog-3122685766060763329.post-69550565772358463692012-12-16T16:30:00.001+01:002012-12-16T16:30:39.654+01:00Windows Phone 8: Voice command support<p>I really love it, if the implementation of rich user functions is easy – and the addition of voice command support for a Windows Phone 8 app is very easy.</p> <p>With Windows Phone 8 you can add additional startup commands for your app which can be used to deep link in your app functions (see details here: <a title="http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj206959(v=vs.105).aspx" href="http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj206959(v=vs.105).aspx">http://msdn.microsoft.com/en-us/library/windowsphone/develop/jj206959(v=vs.105).aspx</a>)</p> <p>In my WorkTime app I want to have a new voice command “WorkTime add entry”. </p> <h3>What are the necessary steps?</h3> <p>Adding a new <em>Voice Command Definition</em> file to the project.

<p>The result is that your app will now support a command “NewEntry” which will be executed if the user presses the Windows button for a few seconds and speaks:</p>
<p>“WorkTime add new entry” or “WorkTime new” or “WorkTime add a new entry”</p>

Windows Phone 8 development with all the fun and pains, if you want to implement pattern like MVVM straight forward. Especially this week I fight with a general validation mechanism. I will post some of my approaches to implement a very smart solution at the next days:</p> <p>Validation code is than looking in the view model constructor like this:</p><pre class="csharpcode"> AddValidationFor(() => CustomerName)
.When(x => <span class="kwrd">string</span>.IsNullOrEmpty(x._customerName))
.Show(AppResources.InvalidNotNullOrEmpty);
AddValidationFor(() => OrderName)
.When(x => <span class="kwrd">string</span>.IsNullOrEmpty(x._orderName))
.Show(AppResources.InvalidNotNullOrEmpty);
AddValidationFor(() => ProjectHoursMax)
.When(x => x._projectHoursMax<=0)
.Show(AppResources.InvalidZeroNotAllowed);
AddValidationFor(() => Start)
.When(x => x._end <= x._start)
.Show(AppResources.InvalidStartIsGreaterThanEnd);</pre>
<p>Here are some screenshots of the WorkTime app (sorry in German, but English will be also supported. Besides multi language support with sharing Resources among assemblies will be another next post – I need more time :-():</p><pre class="csharpcode"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgcxIU9aAtjWFN1uim8e128upJdLE2_tpnUei5_qGiojHZ07CNbGbwpWr8KAKirz5xoEcBlGHBOcbCTE1cFfrYcYOB-nuc0f6NIgnkz80MSYCghrHqDRyclqTOfnejCdV4AZTriEqNLWrY/s1600-h/wp_ss_20121202_0016%25255B2%25255D.png"><img title="wp_ss_20121202_0016" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; display: inline; padding-right: 0px" border="0" alt="wp_ss_20121202_0016" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh-B2s-kCSg3UJuh3zrKfELPna5KvzDz-ccZDWhAH7NI3eOmA8PD3q5Q5H98mJYazVA9cfAB5a8KvZwfKMY9IRYtycYo4racKUVcQIBkNxSvwYhqbOC7QqW0LczxffXd33YFCJ_6KYiY2M/?imgmax=800" width="148" height="244"></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgBX-OMjsxf-UAEjD03NpTlNvMlFYlyPeTdqCJpdbgwY0qIn6WIKQIlA9LSaL2q2NKgXiKEoseoKmkHcC2E1lyaVn5TsfDdd-vdIjDuuWcuQmaiVfbaQxL2kZE0aNsf-ZDZpFA_N8VbQ3I/s1600-h/wp_ss_20121202_0007%25255B2%25255D.png"><img title="wp_ss_20121202_0007" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; display: inline; padding-right: 0px" border="0" alt="wp_ss_20121202_0007" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhkiwB_qqRaGhFXj8O4mI3pajv-W-5hgxtFeUW__IJS6HxgcV0cOvLNDsmRpBA7XV89JLNEzCfzHtU_bhK4dtq1nJZs5_bVgWXf4zlm69B3TcEoxN9D4lEM_T_NWL8U2ttSYIqe5LQit8U/?imgmax=800" width="148" height="244"></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiLAFxpgtSR7n7or-zKfc5TV3xIv8k0FnprIelF4BlqW2gTt6yVIo7ac4mnj2ZzQJ5unGJ68pG9ykmB_0fm7yPvj-n3Ltibk_sdtGAGK8OLvCcOprULRIoPe1Bb9knCVGVopP4FhMNx4UU/s1600-h/wp_ss_20121202_0008%25255B2%25255D.png"><img title="wp_ss_20121202_0008" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; display: inline; padding-right: 0px" border="0" alt="wp_ss_20121202_0008" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg7lnkrEIfvPBgjKH-mkZpjheVXXk1jHfGDlUrDjKgpxKGEOHC4Z92lWV0xOps5RfYupmpoT5hju2gpy0Ii3TTdm848MqMPpSdqsAuGkLJ_3f3DvAQFoSuDP8aZ6NEEMmpqDTidQJe4vSs/?imgmax=800" width="148" height="244"></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhzHha1DQcpdAUw9npsDheu9mqXXuKQ2G0PdaQvL51RborM0TLYSyKMAJKQSQWzfYK_DsQUPdUmFVmjGTQdcs-6ST5hesHQnKR5pWN_9y1YLbVzBCUgP6F9fE7W6cszxaurZr3xg7rgTmQ/s1600-h/wp_ss_20121202_0009%25255B2%25255D.png"><img title="wp_ss_20121202_0009" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; display: inline; padding-right: 0px" border="0" alt="wp_ss_20121202_0009" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhCSuDB4cZ9LSnSi9XydPSoAATuf5JXj-jdYDMVZdOt22Y_5c4xCFDjZ31wudfKNHgLAC3VBiMTDFCGAis_BQnpLcaKwDriKjPoQwpQ8BxKHr-_KGJRifDz9vE47gvKp9gHMKtqIxeBSQs/?imgmax=800" width="148" height="244"></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi8MKJ5iRAoFLraGmXaiWguoA1tdp851F6X7zrxwaZ_X4nUeG4tehIAWY7pD61teMemyivd9VUtveD4A4YhtwuL5Je1sW5z0AFvppGOUzOZbs38uEyQhnTQF193KBBYh39sP-DYCF0pDJA/s1600-h/wp_ss_20121202_0010%25255B2%25255D.png"><img title="wp_ss_20121202_0010" style="border-top: 0px; border-right: 0px; background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; display: inline; padding-right: 0px" border="0" alt="wp_ss_20121202_0010" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgF58YlTY-NE07mrqyTZn0sAqASegSAMz2O2ib93Q7ZaEQhSpUOjNPRqUQjvL3q9SwM1LMvPk4z2Q1SUODliAPDsUkdiIkWmQ968nW9WHn4xM1Ph61MwBEytCXmSbv-p_7AW4-GtJt_mVE/?imgmax=800" width="148" height="244"></a></pre>

At this time I tried a second problem solution and made the <em>SelectedIndex</em> my binding property. In my Viewmodel I have to define therefore a method which maps my <em>SelectedIndex</em> to the instance in my list which is populated in the ListPicker (the WorkTasks ObservableCollection):</p><pre class="csharpcode"><span class="kwrd">private</span> <span class="kwrd">int</span> GetWorkTaskIndexFromId(<span class="kwrd">string</span> id)
{
<span class="kwrd">for</span> (<span class="kwrd">int</span> index = 0; index < <span class="kwrd">this</span>.WorkTasks.Count; index++)
{
<span class="kwrd">if</span> (<span class="kwrd">this</span>.WorkTasks[index].UniqueId == id)
{
<span class="kwrd">return</span> index;
}
}
<span class="kwrd">return</span> 0;

<p>My property for the SelectedIndex in the ViewModel looks like this:</p><pre class="csharpcode"> <span class="kwrd">public</span> <span class="kwrd">int</span> SelectedWorkTaskIndex
{
get
{
<span class="kwrd">return</span> _selectedWorkTaskIndex;
}
set
{
_selectedWorkTaskIndex = <span class="kwrd">value</span>;
<span class="kwrd">if</span> (_allowedToChangeValue && _selectedWorkTaskIndex >= 0)
{
<span class="kwrd">this</span>.SelectedEntry.WorkTask = WorkTasks[<span class="kwrd">value</span>];
}
<span class="kwrd">this</span>.RaisePropertyChanged(<span class="str">"SelectedWorkTaskIndex"</span>);
}
}
</pre>

The last step was to set the SelectedWorkTaskIndex corerctly after loading the instance of my ViewModel connected model. This is done in my implementation of the LoadWorkTask RelayCommand:</p><pre class="csharpcode"> <span class="kwrd">private</span> <span class="kwrd">void</span> LoadWorkTaskList()
{
<span class="kwrd">try</span>
{
....
_allowedToChangeValue = <span class="kwrd">true</span>;
SetWorkTask();
}
<span class="kwrd">catch</span> (Exception error)
{
.....
}
}
</pre>

They have forgotten to declare a DependencyObject for the <em>SelectedItem</em> property so you can not bind the <em>SelectedItem</em> property. Or maybe they want to be compatible with this bug :-)</p> <p>To resolve this I decided in my current project to define a new class <em>LongListSelector</em> in my project namespace which is derived from the <em>LongListSelector</em> control. Here I can define a dependency property and a LongListSelector_SelectionChanged method to handle the binding. It is is important to declare the property in the new class as New, because we want to override the <em>SelectedItem</em> property in the Microsoft control.</p> <p>Here is my code to do this:</p><pre class="csharpcode"><span class="kwrd">public</span> <span class="kwrd">class</span> LongListSelector : Microsoft.Phone.Controls.LongListSelector
{
<span class="kwrd">public</span> LongListSelector()
{
SelectionChanged += LongListSelector_SelectionChanged;
}
<span class="kwrd">void</span> LongListSelector_SelectionChanged(<span class="kwrd">object</span> sender, SelectionChangedEventArgs e)
{
SelectedItem = <span class="kwrd">base</span>.SelectedItem;
}
<span class="kwrd">public</span> <span class="kwrd">static</span> <span class="kwrd">readonly</span> DependencyProperty SelectedItemProperty =
DependencyProperty.Register(
<span class="str">"SelectedItem"</span>,

<span class="kwrd">typeof</span>(LongListSelector),
<span class="kwrd">new</span> PropertyMetadata(<span class="kwrd">null</span>, OnSelectedItemChanged)
);

var selector = (LongListSelector)d;
selector.SelectedItem = e.NewValue;
}
