Android Widget Collection View: how to get appWidgetId of calling widget from RemoteViewsFactory?

Question

Is there any way to access the calling appwidgetId inside RemoteViewsFactory's getViewAt method? I have data persisted by appWidgetId and without access to appWidgetId it doesn't work.

Or, is there a pattern for multiple widgets backed by collection views?

Answer 1

I was getting the same id for every widget, because I was missing the Intent.setData() line:

Intent remoteViewsServiceIntent = new Intent(context, RemoteViewsService.class);
remoteViewsServiceIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId);
remoteViewsServiceIntent.setData(Uri.parse(remoteViewsServiceIntent.toUri(Intent.URI_INTENT_SCHEME)));
views.setRemoteAdapter(R.id.widget_listview, remoteViewsServiceIntent);
