    copied!<p>I tried to get a resizeable widget working, but it won't. I've got a database which I use with greenDAO. So my app should work on Android 2.3+. That's why I want to have got the following widgets:</p> <ul> <li>4x2 with 2 items</li> <li>4x3 with 3 items</li> <li>4x4 with 4 items</li> <li>4x5 with 5 items</li> </ul> <p>In preHoneycomb these <code>Widgets</code> should just show the first items and opens the app on click.</p> <p>In Android 3+ these <code>widgets</code> should be realizable and scrollable. My problem is that my Widget Service class is never called. So nothing inside the widget will be filled :-</p> <p>Here is my code:</p> <pre><code>public class WidgetProvider extends AppWidgetProvider { private static final String TAG = "WidgetProvider"; @TargetApi(14) @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { Log.i(TAG, "Update!!"); for (int i = 0; i &lt; appWidgetIds.length; ++i) { int appWidgetId = appWidgetIds[i]; Intent intent = new Intent(context, TimetableActivity_.class); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); Intent svcIntent = new Intent(context, WidgetService.class); svcIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]); svcIntent.setData(Uri.parse(svcIntent .toUri(Intent.URI_INTENT_SCHEME))); RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget); views.setOnClickPendingIntent(R.id.img_widget_home, pendingIntent); views.setRemoteAdapter(R.id.btn_widget_refresh, svcIntent); Intent update = new Intent(context, WidgetProvider.class); intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE); intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, appWidgetIds); PendingIntent pend = PendingIntent.getBroadcast(context, 0, update, PendingIntent.FLAG_UPDATE_CURRENT); views.setOnClickPendingIntent(R.id.btn_widget_refresh, pend); appWidgetManager.updateAppWidget(appWidgetId, views); } super.onUpdate(context, appWidgetManager, appWidgetIds); } @TargetApi(11) public class WidgetService extends RemoteViewsService { private static final String TAG = "WidgetService"; @Override public RemoteViewsFactory onGetViewFactory(Intent intent) { Log.i(TAG, "WidgetService called"); return new ListRemoteViewsFactory(this.getApplicationContext(), (TimetableApplication_) this.getApplication(), intent); } } class ListRemoteViewsFactory implements RemoteViewsService.RemoteViewsFactory { private static final String TAG = "ListRemoteViewsFactory"; private Context mContext; private TimetableApplication_ application; private List&lt;Events&gt; events = new ArrayList&lt;Events&gt;(); public ListRemoteViewsFactory(Context context, TimetableApplication_ application, Intent intent) { this.mContext = context; this.application = application; } public int getCount() { return events.size(); } public RemoteViews getViewAt(int position) { Log.i(TAG, ""+getCount()); String title = ""; String description = ""; Events e; if ((e = events.get(position)) != null) { title = e.getSubjects().getTitle(); description = e.getStart().toGMTString(); } RemoteViews rv = new RemoteViews(mContext.getPackageName(), R.layout.widget_item); rv.setTextViewText(R.id.txt_widget_item_title, title); rv.setTextViewText(R.id.txt_widget_item_description, description); return rv; } public RemoteViews getLoadingView() { return null; } public int getViewTypeCount() { return 1; } public long getItemId(int position) { return position; } public boolean hasStableIds() { return true; } public void onDataSetChanged() { if (events != null) { events.clear(); } events = application.getEvents(); } @Override public void onCreate() { } @Override public void onDestroy() { } } </code></pre> <p>And here is my Manifest file:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
