Prevent MediatorLiveData event emit on config change

Question

In architecture samples , There is an extension of MutableLiveData named SingleLiveEvent which helps us prevent a LiveData from firing on phone rotation or config change.

This (SingleLiveEvent) avoids a common problem with events: on configuration change (like rotation) an update can be emitted if the observer is active.

But we can't cast MediatorLiveData to SingleLiveEvent. How can we avoid MediatorLiveData emitting on config change?

Answer 1

   <activity android:name=".appActivity.video.playVideo.PlayVideoFromUri"
        android:configChanges="keyboardHidden|orientation|screenSize"></activity>

issue is Activity recrate on orientation change just add above lines in mainfest file.
