java.lang.IllegalStateException: Only fullscreen opaque activities can request orientation

Question

I am facing the problem while retrieving the contacts from the contact book in Android 8.0 Oreo java.lang.IllegalStateException: Only fullscreen opaque activities can reques

Answer 1

If you use a fullscreen transparent activity, there is no need to specify the orientation lock on the activity. It will take the configuration settings of the parent activity. So if the parent activity has in the manifest:

android:screenOrientation="portrait"

your translucent activity will have the same orientation lock: portrait.
