Question

SOLVED!

My Activity Stack looks like this, excuse the rough diagram!

A-->B-->C
    '-->D

If I press back button in activity B I go back to A as expected.
However, if I press back button in Activity C or D I go back to A instead of B.
In my mind this could be caused by two things
1)Activity B quits when it opens the intents for C or D
2)the back button is somehow being called twice?

I have looked closely at the click listeners in activity B that start the intents expecting to find a finish() call in there but there isn’t.
I also check the onBackPressed() methods of activites C and D to see if I was manually opening activity A…but I wasn’t.

here’s the onResume method of activity A

protected void onResume() {
        super.onResume();
        screenOn(SCREEN_ON_DURATION);
        mWakeLock.acquire();

    }

here’s the way I’m starting intents C and D

            Bundle info = new Bundle(); 
            info.putString("classId", ""+classId );


            Intent intent = new Intent(Notebook.this, StudentChooser.class);
            intent.putExtras(info); 

            Notebook.this.startActivity(intent);

Can anyone help?

Edit: I discovered finish() in my onUserLeaveHint() that’s what the problem was!

Answer 1

The reason may be that you are using finish() in your previous activity,For example
A->B->C
            Intent intent = new Intent(B.this, C.class);
            startActivity(intent);
            finish();

finish() is destroying B activity hence the control is going on activity A on back button
