How to implement stable work for android widget?

Answer 1

I solved my issue. It turned out that process of widget doesn't stop when user pushing "Force Stop" in system menu or pushing "Clear All" in Xiaomi MIUI. Main thread stay alive and continue to receive system messages. But static fields of AppWidgetProvider which references to AppWidgetManager, RemoteViews и ComponentName becames NULL. I just do recreate new objects.

    public class AppWidget extends AppWidgetProvider {
    public static RemoteViews remoteViews;
    public static AppWidgetManager appWidgetManager;
    public static ComponentName watchWidget;
    @Override
    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent);

        if(remoteViews == null)
            remoteViews = new RemoteViews(context.getPackageName(), R.layout.app_widget);
        if(appWidgetManager == null)
            appWidgetManager = AppWidgetManager.getInstance(context);
        if(watchWidget == null)
            watchWidget = new ComponentName(context, AppWidget.class);
    }
}
