Android AppWidgetProvider onReceive not called by button click

Question

I have a widget running under android, and I would like it to be updated when a user clicks a button on widgets.

For some reason, the onReceive method is never called when a button is pressed after the widget is installed.

I have an onUpdate method similar to this in the AppWidgetProvider class:

@Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { super.onUpdate(context, appWidgetManager, appWidgetIds); for (int i = 0; i < appWidgetIds.length; ++i) { final RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.appwidget_provider); final Intent nextIntent = new Intent(context, TestAppWidgetProvider.class); nextIntent.setAction(TestAppWidgetProvider.NEXT_ACTION); nextIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]); final PendingIntent refreshPendingIntent = PendingIntent.getBroadcast(context, 0, nextIntent, PendingIntent.FLAG_UPDATE_CURRENT); rv.setOnClickPendingIntent(R.id.next, refreshPendingIntent); appWidgetManager.updateAppWidget(appWidgetIds[i], rv); } } 

And then in my on receive I have a method that looks like this:

 @Override public void onReceive(Context ctx, Intent intent) { super.onReceive(ctx, intent); final String action = intent.getAction(); if (action.equals(PREV_ACTION)) { Toast.makeText(ctx, "Previous clicked..", Toast.LENGTH_SHORT).show(); } else if (action.equals(NEXT_ACTION)) { Toast.makeText(ctx, "Next was clicked..", Toast.LENGTH_SHORT) .show(); } else { Toast.makeText(ctx, "Other action..", Toast.LENGTH_SHORT).show(); } } 

I have in my manifest file:

 <receiver android:name="com.test.android.widget.TestAppWidgetProvider" > <intent-filter > <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> </intent-filter> <intent-filter > <action android:name="com.test.android.widget.PREV" /> </intent-filter> <intent-filter > <action android:name="com.test.android.widget.NEXT" /> </intent-filter> <meta-data android:name="android.appwidget.provider" android:resource="@xml/appwidget_info" /> </receiver> 

After installing the widget and clicking on the next button, the onReceive method is never called for some reason ...

Answer 1

Fixed, it turned out to be trivial.

This happened because onReceive was not even called when the widget was created, so the event listener was not configured.

Added some code that was in onReceive (setting setOnClickPendingIntent, etc.) for a function that is called when the widget's customization activity is ready to update the widget.
