Android Tutorial AdMob mediation - UnityAds (not tested)

This tutorial assumes that you already have FirebaseAdMob2 implemented in your app.

Implementation is NOT tested in B4A. You can test it if you want.
If any of you have tested the implementation, please share your observations, as I don't have any project written with B4A.

If you have problem compiling app please check THIS post.

1. Follow Step 1 and Step 2 in this tutorial: https://developers.google.com/admob/android/mediation/unity
2. Download UnityAds library from HERE and unzip it in additional libraries folder. You also can test example app from post #1 to check is everything is OK with UnityAds, you can have problem with compiling. If you have problem compiling app, please check THIS post.
3. Download UnityAds adapter for mediation from HERE and copy unity-4.14.1.0.aar to additional libraries folder.
4. minSdkVersion must be set to 23.
5. Include UnityAds and OkHttp library in your project. You don't need to initialize libraries, just include them by checking library in Libraries Manager tab inside B4A.
