Very simple code, but got error “Activity has been destroyed” when use Fragment

Question

I made a very simple Activity which shows a simple ListFragment like below:

My Activity:

public class MyActivity ex         


        

Answer 1

Still bad, because got error “Activity has been destroyed”

ava.lang.IllegalStateException: Activity has been destroyed fragmentTransaction.commitAllowingStateLoss();

So my solution is add check if (!isFinishing()&&!isDestroyed())

 if (!isFinishing()&&!isDestroyed()) {
                        fragmentTransaction.commitAllowingStateLoss();
                    }
                }
