In node-modules/react-native-admob/android/build.gradle

replace ====> implementation ‘com.google.android.gms:play-services-ads:+.’

With ====> implementation ‘com.google.android.gms:play-services-ads:19.8.0’

Hope this will solve your issue

Install the beta version instead…

yarn add [email protected]

Don’t forget to delete your node-modules folder, and clean your build folder as a precaution

I’m trying to add admob to my project, but when installed, my project can’t install on my phone, does anyone know what it might be?

error bellow

Configure project :react-native-admob
WARNING: Configuration ‘compile’ is obsolete and has been replaced with ‘implementation’ and ‘api’.
It will be removed soon. For more information see: http://d.android.com/r/tools/update-dependency-configurations.html

To suppress this warning, remove “buildToolsVersion ‘23.0.1’” from your build.gradle file, as each version of the Android Gradle
