UI flickering while back pressed in android studio

Question

I have an android app with a number of activities. While switching between activities and then press back button a very short flickering occurs. I test adding this line in both onBackPressed and onResume :

overridePendingTransition(0,0);

also I add this line to my theme style:

<item name="android:windowAnimationStyle">@null</item>

I did not find any solution. here is a short video:
Thanks for any help

Answer 1

You can add this line to your theme style. It will delay a little bit the presentation by removing the flickering.

<item name="android:windowDisablePreview">true</item>
