I have found a lot of similar questions on the stackoverflow but their solutions don't work in my case. They are connected with onSaveInstanceState
method and the Support Library especially.
I have Activity
which runs on one event this code:
MyDialogFragment.showMyDialog(name, this, this);
name
parameter is the String object. Second parameter (this
) is the just Activity
class object and the third one (also this
) is the simple interface. This my Activity
implements this interface. showMyDialog()
is of course static method. This is it body:
MyDialogFragment fragment = new MyDialogFragment(listener, "Hello " + name);
fragment.show(activity.getFragmentManager(), "myDialog");
This is working good at the first try. But at the second I am getting this exception:
E/AndroidRuntime﹕ FATAL EXCEPTION: main
Process: com.example.myapp, PID: 20759
java.lang.IllegalStateException: Activity has been destroyed

In general this is the steps to reproduce my exception:
Activity
- event is received so MyDialogFragment
is shown.Activity
once more time - MyDialogFragment
is shown again.MyDialogFragment
once more. But at this moment I am getting exception.However, when I skip the second point and start to typing wrong code for validation, MyDialogFragment
will be shown without any issue. Strange behaviour.
I have tried with non-static method, setRetainInstance(true)
and also commitAllowingStateLoss
. But there was no difference.
It is a bit odd - or maybe just a bug in this Android functionality. I have added block try catch
to catch throwing exception in this way:
MyDialogFragment fragment = new MyDialogFragment(listener, "Hello " + name);
try {
fragment.show(activity.getFragmentManager(), "myDialog");
} catch (Exception e) {
e.printStackTrace();
}
And of course exception is still throwing (and catching at this moment) and what is interesting my dialog fragment is recreating in correct way and user can interact with it.
