Android : How to dismiss a DialogFragment on orientation change?

Question

I would like dismiss a DialogFragment on orientation change.

The problem is that the OnConfigurationChanged() is never called.

And call :

this.dismiss();

from the OnDetach() method, returns a null pointer exception. What could I do?

Overriding :

public void onPause() {
    super.onPause();

    this.dismiss();
}

instead of OnConfigurationChanged(), did the trick.

Note that this also causes the DialogFragment to be dismissed whenever it goes into pause state for any reason, such as for example another Activity coming into the foreground. – Trevor Oct 07 '17 at 19:50

Add this to your manifest

android:configChanges="orientation|screenSize"

I added it, but OnConfigurationChanged() is still not called. I think it is because it is a Fragment, not an Activity. – Greelings Mar 20 '16 at 19:21
Yes, I already saw this link. My problem is specific to the DialogFragment class. – Greelings Mar 20 '16 at 19:29

perhaps you could tie into the onConfigurationChanged() method of the activity that opens the dialog. When you show the Dialog you set a TAG, you can use this tag to find the dialog and dismiss it from the calling activity – Terry W Mar 20 '16 at 19:52
