I'm currently trying to add a ListView to my widget. Sadly, my RemoteViewsService does not get called.

Here's my widget refresh code :

RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_today_layout);

Intent intent = new Intent(context, TodayWidgetService.class);
intent.putExtra("package", context.getPackageName());
intent.putExtra("items", items.toArray(new String[items.size()])); // items is just a List<String>

views.setRemoteAdapter(R.id.widget_today_content, intent);
manager.notifyAppWidgetViewDataChanged(ids, R.id.widget_today_content);

And the service code (in TodayWidgetService) :

@Override
public RemoteViewsFactory onGetViewFactory(final Intent intent) {
    System.out.println("Called");
    return new TodayWidgetReceiver.WidgetFactory(intent.getStringExtra("package"), intent.getStringArrayExtra("items"));
}

As you can see, I print a Called message each time the service is executing. That's why I'm here : the message isn't in my console (therefore, the service is not called).

I added it in my AndroidManifest.xml :

<application
...
    <service
        android:name="services.TodayWidgetService"
        android:permission="android.permission.BIND_REMOTEVIEWS">
    </service>
</application>

Thanks for any help !


Your onUpdate methods needs to be like this one:

public void onUpdate(Context context, AppWidgetManager appWidgetManager,
int[] appWidgetIds) {
    // update each of the app widgets with the remote adapter
    for (int i = 0; i < appWidgetIds.length; ++i) {

        // Set up the intent that starts the StackViewService, which will
        // provide the views for this collection.
        Intent intent = new Intent(context, StackWidgetService.class);
        // Add the app widget ID to the intent extras.
        intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]);
        intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
        // Instantiate the RemoteViews object for the app widget layout.
        RemoteViews rv = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
        // Set up the RemoteViews object to use a RemoteViews adapter.
        // This adapter connects
        // to a RemoteViewsService  through the specified intent.
        // This is how you populate the data.
        rv.setRemoteAdapter(R.id.stack_view, intent);

        // The empty view is displayed when the collection has no items.
        // It should be in the same layout used to instantiate the RemoteViews
        // object above.
        rv.setEmptyView(R.id.stack_view, R.id.empty_view);

        //
        // Do additional processing specific to this app widget...
        //

        appWidgetManager.updateAppWidget(appWidgetIds[i], rv);
    }
    super.onUpdate(context, appWidgetManager, appWidgetIds);
}

So check these things:

  1. are you calling the appWidgetManager.updateAppWidget(appWidgetIds[i], rv); in your refresh code?

  2. You need to set appWidgetId and data to the Service intent, like so:

    intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetIds[i]); intent.setData(Uri.parse(intent.toUri(Intent.URI_INTENT_SCHEME)));
