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

In android Oreo (API 26) you can not change orientation for Activity that have below line(s) in style

 true

or

 true

You have several way to solving this :

1) You can simply remove above line(s) (or turn it to false) and your app works fine.

2) Or you can first remove below line from manifest for that activity

android:screenOrientation="portrait"

Then you must add this line to your activity (in onCreate())

    //android O fix bug orientation
    if (android.os.Build.VERSION.SDK_INT != Build.VERSION_CODES.O) {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }

3) You can create new styles.xml in values-v26 folder and add this to your style.xml. (Thanks to AbdelHady comment)
