How to see if the next time I press the back (hardware) button, will take me on the screen. My question is basically: Is there a way to see the size of the Activity Stack (API level 7).
boolean Activity.isTaskRoot(); Since: API Level 1
Return whether this activity is the root of a task.
The root is the first activity in a task.
Just don’t do it in onCreate() as the calling activity may not have finish()ed itself yet.
