Screen orientation - Android

On Android, make sure that the android:screenOrientation attribute is not used anywhere.

Open Android Studio and press the Shift key twice to open the search dialog. Search for android:screenOrientation. In case there are search results, remove the attribute.

You probably need to make additional code adjustments to make sure the all orientations are working as intended.

To listen to orientation changes, add android:configChanges="orientation" to your manifest. Then, override the onConfigurationChanged to receive configuration notifications. Use the orientation property of the Configuration object to check the new orientation.

<activity
    android:name=".ApptActivity"
    android:screenOrientation="portrait" <!-- Remove -->
    android:configChanges="orientation" <!-- Add -->
</activity>

override fun onConfigurationChanged(newConfig: Configuration) {
    super.onConfigurationChanged(newConfig)

    when (newConfig.orientation) {
        Configuration.ORIENTATION_PORTRAIT -> {
            // Portrait logic
        }
        Configuration.ORIENTATION_LANDSCAPE -> {
            // Landscape logic
        }
        else -> {
            // Ignored
        }
    }
}
