The project have iOS & Android Version , both written by React Native. The Old version （called version 2.7) is live.
I have added new feature ( called Ads. , version 2.8 ) to iOS version ,and the iOS version is live (published at AppStore) . Now I hope you move the new feature (called Ads.) code to Android version. Let the RN code fit & match the android version. Do not affect the original function that on old Android version( called 2.7) and keept it working!
I will provide old android project code and new feature Ads ’s RN Code for you . all API and UI can refer to iOS version. because the iOS Version is live.
If you are goods at ReactNative, You can do this work in half a day or a day.
