Sometimes, although the MediationAdaptersDependencies.xml is populated, the mainTemplate.gradle file’s dependency section may still be empty even after resolution or forcing resolution:
implementation fileTree(dir: 'libs', include: ['*.jar']) // Android Resolver Dependencies Start // Android Resolver Dependencies End **DEPS** }
This Play Services Resolver issue can occur if the Custom Main Manifest is currently added.
To resolve this issue with the Custom Main Manifest, remove it, resolve it, then add it back.
