I use MoPub under AdMob mediation.
To reduce APK size, I’d like to use MoPub modular dependencies, as I only use banner ads.
But there seems to be a bug: some “Native ads” code is called (apparently by the AdMob adapter) when a banner is shown, leading to a NoClassDefFoundError exception and app crash.
Please advise how to fix this issue.
build.gradle:
implementation('com.mopub:mopub-sdk-banner:5.3.0@aar') {
transitive = true
}
implementation('com.google.ads.mediation:mopub:5.3.0.1')
