If you are getting an error like the one in the picture while producing APK even though you have created your mobile app,
First of all, you need to check your in-app images, app icon, or menu background images that you add to your app.
Furthermore, if you have added a Music & SoundCloud module to your app and defined your SoundCloud account here, you need to check this area as well. If there is an error in your SoundCloud account name, you will receive an error during APK generation.
If you are getting an error in APK generation despite making these arrangements, you can contact the Mobiroller support team at email@example.com.
