I'm creating a notification from a service with the following code:
NotificationManager notificationManager = (NotificationManager) ctx
.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence tickerText = "bla ...";
long when = System.currentTimeMillis();
Notification notification = new Notification(R.drawable.icon,
tickerText, when);
Intent notificationIntent = new Intent(ctx, SearchActivity.class).
putExtra(SearchActivity.INTENT_SOURCE,
MyNotificationService.class.getSimpleName());
PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0,
notificationIntent, 0);
notification.setLatestEventInfo(ctx, ctx.getString(R.string.app_name),
tickerText, contentIntent);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notificationManager.notify(1, notification);
The logs clearly says that the the method startActivity is called twice times:
04-02 23:48:06.923: INFO/ActivityManager(2466): Starting activity: Intent { act=android.intent.action.SEARCH cmp=com.xy/.SearchActivity bnds=[0,520][480,616] (has extras) }

Why are they started twice?
There are two identical questions on stackoverflow: here and here.
But they do not explain what the initial issue could be and they do not work for me. E.g. changing to launchMode singleTop is not appropriated for me and it should work without changing launchMode according to the official docs (see Invoking the search dialog).
Nevertheless I also tried to add the following flags to notificationIntent
Intent.FLAG_ACTIVITY_CLEAR_TOP | PendingIntent.FLAG_UPDATE_CURRENT
but the problem remains the same.
