  1. POAndroid Widget - Weird "loading Widget" error
    text
    copied!<p>I am having a weird problem with my configurable clock widget I´m not being able to debug :( This is my first Widget an it´s an easy one ;), It´s a background configurable clock widget. When the user selects the widget the configuration activity is launched. In this activity the user may choose the clock´s widget background. When the user finishes the configuration a "standard clock widget" with the user´s background appears on the launcher´s screen and that´s all. I tested it thoroughly and it seems to works right till... The problem I´ve got it´s that from time to time when I turn on and unlock the screen, my widget it´s "gone" and I´ve got a grey box with the dreaded "Problem loading Widget" error on it :( So, I´ve got an error that I can´t get a reproducible scenario for it, maybe a life-cycle widget method error related? When the error appears I see no problem in the logcat so I´m completely lost.</p> <p>This is the easy code for this widget: (GB 2.3.3). I´ve taken out not important bits.</p> <p>1.- Widget Provider xml</p> <pre><code>&lt;appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android" android:minHeight="190dp" android:minWidth="170dp" android:configure="......" android:initialLayout="@drawable/......" android:updatePeriodMillis="30000" &gt; &lt;/appwidget-provider&gt; </code></pre> <p>2.- AndroidManifest.xml</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="........" android:versionCode="1" android:versionName="1.0" &gt; &lt;uses-sdk android:minSdkVersion="10" android:targetSdkVersion="10" /&gt; &lt;application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" &gt; &lt;activity android:name="........" android:label="@string/app_name" android:screenOrientation="portrait" &gt; &lt;intent-filter&gt; &lt;action android:name="android.appwidget.action.APPWIDGET_CONFIGURE" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;receiver android:name="........." &gt; &lt;intent-filter&gt; &lt;action android:name="android.appwidget.action.APPWIDGET_UPDATE" /&gt; &lt;/intent-filter&gt; &lt;meta-data android:name="android.appwidget.provider" android:resource="@xml/........" /&gt; &lt;/receiver&gt; &lt;/application&gt; &lt;/manifest&gt; </code></pre> <p>3.- Widget Layout I´ve got several widget layouts.The user selects one from the configuration activity All the layouts are almost identical with minor changes (ImageView drawable):</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/LinearLayout01" android:layout_width="160dp" android:layout_height="200dp" android:orientation="vertical" &gt; &lt;ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:adjustViewBounds="true" android:scaleType="fitXY" android:src="@drawable/...." /&gt; &lt;AnalogClock android:layout_width="wrap_content" android:layout_height="138dp" android:layout_gravity="bottom" android:dial="@drawable/...." android:hand_hour="@drawable/...." android:hand_minute="@drawable/...." /&gt; &lt;/FrameLayout&gt; </code></pre> <p>4.- Widget Provider (Java)</p> <pre><code>public class ClockProvider extends AppWidgetProvider { public static int anoEscudo; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { super.onUpdate(context, appWidgetManager, appWidgetIds); RemoteViews remoteView = null; for (int appWidgetId : appWidgetIds) { // Actualizamos la variable para luego poder modificar el fondo switch (anoEscudo) { case (...): remoteView = new RemoteViews(context.getPackageName(), R.layout....); break; ... } appWidgetManager.updateAppWidget(appWidgetId, remoteView); } } } </code></pre> <p>5.- Configuration Activity (Java)</p> <pre><code>package ...; public class ConfigurationActivity extends Activity { private int appWidgetId; ImageView escudo; TextView descripcion; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // get the appWidgetId of the appWidget being configured Intent launchIntent = getIntent(); Bundle extras = launchIntent.getExtras(); appWidgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); // set the result for cancel first // if the user cancels, then the appWidget // should not appear Intent cancelResultValue = new Intent(); cancelResultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId); setResult(RESULT_CANCELED, cancelResultValue); // show the user interface of configuration setContentView(R.layout.activity_configuration); // Setting configuration Activity graphical elements // .. } //Changing the Widget configuration private void ... (View view) { switch (escudoSeleccionado) { case 1: ClockProvider.anoEscudo = ...; break; ... } } // Finish the configuration Activity public void ... (View view) { Intent resultValue = new Intent(); resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId); setResult(RESULT_OK, resultValue); new ClockProvider().onUpdate(this, AppWidgetManager.getInstance(this), new int[] { appWidgetId }); finish(); } } </code></pre>
