How to implement Admob using cocos2dx - C ++

I do not have programmers around me so I can not talk to them and I am in trouble. please help me. I tried various studies alone, Firebase, SDKBOX etc, but I tried to look at it, but I could not do it. I think that you can understand how to organize in a primitive way without using the SDK, so please let me know. The iOS is successfully implemented. I am aiming for success in Android Studio. What I’d like to do is write the interface and ID of admob banner advertisement in Activity.JAVA of Android Studio, create a JNI that connects it, and display / hide the banner ad from Xcode’s .cpp. Please tell me the flow of the details in detail. Also, please show me if you have samples.

You can use our Cocos Helper which we designed specifically for this purpose.
