Question

Background

I have an app with Admob SDK used in it, to show Interstitial ads (full screen ads).

Reccently Google has updated the SDK, along with many other

Answer 1

please do not use any properties in Android Manifest files AdActivity.

please remove this line from AdActivity in Manifest file

android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"

Just simply add this following line to Android Manifest file.

If you want to set your desired activity as portrait mode please add this following line to your activities onCreate method:

if (android.os.Build.VERSION.SDK_INT != Build.VERSION_CODES.O) {
   activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

For firebase ADS 17.0.0 and upper versions use this line to manifest file.

You can get app id from Admob -> Apps -> your app -> App Settings -> App Id. Please copy and paste this App_Id into your project.
