Android Notification Opens On Existing Activity

I am in trouble with notification intents. I have a service(Service checks for messages and creates notification) which creates notifications. And application has an action bar and via slide menu users can navigate between activities.

https://i.sstatic.net/YJXe6.png

When user clicks notification it opens a new activity on the current activity.(Like an independent new instance). I want to open them in the same instance as if user navigating manually(Like clicking A when on B activity ie)

My current activity launchMode is standard(Although I tried singleTop and singleTask and flags)

Current Notification code :

Intent i = null;
i = new Intent(this, MessagesListActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,i, 0);
Builder notificationBuilder  = new NotificationCompat.Builder(this);
notificationBuilder.setContentTitle(title);
notificationBuilder.setContentText(msg);
notificationBuilder.setSmallIcon(R.drawable.speech_bubble_orange);
notificationBuilder.setContentIntent(contentIntent);
notificationBuilder.setAutoCancel(true);
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Notification notification = notificationBuilder.build();
notificationManager.notify(Constants.UNREADMESSAGESNOTIFICATIONID,notification);

Thanks for your help.

I solved the problem. With this combination new launched activity clears stackback. I also did not change the launchmodes (still standard)

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

If I understood correctly, I think what you are looking for is the TaskStackBuilder. It allows you to create a backstack to provide proper navigation to the Activity being launched by the PendingIntent.

See the docs here for more information.

In your manifest, you have to tag your activity as single instance, and keep the singleTask

android:launchMode= "singleTask" | "singleInstance"

in addition, you may have to remove the single top flag from your intent.
