@bayonmbayo this problem happens because you are calling show before prepare.

Please check the documentation. There are other several issues with this explanation.

I solved by adding some line in the file "BannerExecutor.java", it is about to handle the "NullException" coming from Android-Layout Elements

I upload here the updated file BannerExecutor.java.txt

• The extension of the file finish with ".txt", delete it after uploading -> It has to end with ".java" like this "BannerExecutor.java"

• Then replace the old one with the new file

After updating the file "BannerExecutor.java", ANR and Crash was reduced drastically in the new version of the App 😎

PS : I use only a banner in the App, if you are using an interstitial (AdInterstitialExecutor.java) or a reward interstitial (AdRewardExecutor.java), just handle the "NullException" coming from Android-Layout Elements
