Answer 1

you can use getInstalledProviders for getting list of all installed app widgets.as:

AppWidgetManager mAppWidgetManager= AppWidgetManager.getInstance(context);
List<AppWidgetProviderInfo> installed = mAppWidgetManager.getInstalledProviders();
//YOUR APP WIDGET INFO HERE
AppWidgetProviderInfo appWidgetInfo = mAppWidgetManager.getAppWidgetInfo(appWidgetId);
