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

I faced this problem only in SDK 26 (8.0.0) if using windowIsTranslucent 'true' and forcefully setting orientation:

Here's the solution:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);   

        // fixing portrait mode problem for SDK 26 if using windowIsTranslucent = true
        if (Build.VERSION.SDK_INT == 26) {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);
        } else {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }        
    }
