Answer 1

Both times when you write the package name : 1. When you create a new project in Android Studio and 2. When you create a Configuration File

YOU should write it with lowercase letters - after changing to lowercase it works. If you don't want to waste time just go to you .json file and replace com.myname.MyAPPlicationnamE with com.myname.myapplicationname (for every match in the json file).
