@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.e("", "onStartCommand di AppWidget");
int[] appWidgetIds = intent.getIntArrayExtra("widgetsids");
final int N = appWidgetIds.length;
AppWidgetManager manager = AppWidgetManager.getInstance(this);
// Perform this loop procedure for each App Widget that belongs to
// this provider
for (int i = 0; i < N; i++) {
int appWidgetId = appWidgetIds[i];
Log.e("",
"i=" + Integer.toString(i) + " di "
+ Integer.toString(N));
RemoteViews view = buildUpdate(getApplicationContext(),
appWidgetIds);
// Tell the AppWidgetManager to perform an update on the current
// app widget
manager.updateAppWidget(appWidgetId, view);
}
return (START_NOT_STICKY);
}
@Override
public IBinder onBind(Intent intent) {
