@nite I was able to fix the android studio project and now I can compile and run the app.
I'm using AdColony, InMoby, UnityAds, AdMob and Vungle for mediation but I can't make them work.
Interstitials are not loading, the video reward is working but I think it's loading from Fyber only, and not from mediation networks.
Gradle file Config:
name "Fyber's maven repo"
compile fileTree(dir: 'libs', include: ['*.jar'])
Do I need to add anything else? In iOS, the Fyber mediation configurations are pulled from the Dashboard, not sure if in Android it works same way.
