My app and activity is in my list of recent apps when I receive a notification. When I click on the notification, I want the intent of the notification to be honored. In my case I want to restart the activity (brute force) and pass in the new intent: so, finish then re-create. I am reading about such tags as FLAG_ACTIVITY_NEW_TASK
and FLAG_ACTIVITY_SINGLE_TOP
but I don't understand them enough to know how to force a "finish then re-create` of my activity. And, oh, the activity in question is MainActivity.
The snippet inside GcmListenerService uses
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
for sending the notification intent
Alternatively
If I go with onNewIntent
things get complicated because there maybe DialogFragments being displayed, etc. And I would have to clear everything. That is why finish then re-create seem like the simplest solution to me.
