When you call/start a activity using startActivityForResult function (In my case it is for Facebook login with LoginManager.getInstance().logInWithReadPermissions(this, PERMISSIONS); is there any way to cancel the intent so parent activity onActivityResult will not be called. I want to add a timeout mechanism to my parent activity to prevent long waiting times for the child activity. (When Facebook is blocked/slowed down it takes minutes until onActivityResult is called , so i want to inform the user about the situation on possible timeout)
No, you can't cancel it. However, you could keep track of the fact that you aren't waiting for the onActivityResult() callback any more so that when the method does get called, you remember that you don't care and just ignore it.
