How to dismiss DialogFragment from AsyncTask, when the home button is pressed and the device is resumed with changed rotation

Question

I have an AsyncTask which dismisses the DialogFragment. I am facing a problem when the AsyncTask tries to dismiss the dialog after pressing the home button. dismissAllowingStateloss() helps to this case, but one issue still remains. When I press home button and then rotate, the AsyncTask tries to dismiss the activity, but as the orientation is changed, the activity calls onDestroy() and recreates the stuff. As a result the DialogFragment is on the screen again. setRetainInstance is set to true for the DialogFragment. The normal dismiss() raises IllegalStateException by saying do not call after onSavedInstance().

Any idea how to fix this by keeping the DialogFragment independent from the Activity? I mean without putting tracking variables in the Activity. I do not want to do this, because I do not want to write that stuff for each Activity where I would use this dialog.

Hard to say without code, but generally you can use FragmentManager to remove DialogFragment. — Maxim G, May 19 '16 at 16:14
How can I do that, when after the rotation Activity is destroyed a new one is recreated? — X-HuMan, May 19 '16 at 16:28
You can differentiate a new Activity and restored Activity by savedInstanceState. — Maxim G, May 19 '16 at 16:40
