Android activity recreate itself

Question

My app normally works just fine, until I face a strange problem on specific device. There are 2 activities in App. After I start ActivityB inside of ActivityA, ActivityA starts

Answer 1

Activity A uses layout R.layout.mesajlar_list

Activity B uses layout R.layout.mesajdetaylari

But both have the following line of code:

kapatButton = (ImageView) findViewById(R.id.kapat_button);

Which layout is R.id.kapat_button in? Using the same id in different layouts is a very risky thing to do. I can't guarantee it's causing what you're seeing, but it is the sort of thing that may cause weird behaviour.
