Allow inclusion as Android app module

[gxcare]

With those two files the library can be used as a module in Android apps.

The only requirement for the user is to add the following declaration in the app build.gradle file: ext { compileSdkVersion = 31 }

correct me if im wrong but wont this make it impossible for jvm only projects to use it since it always applies the android framework plugin? 🤔

Yes, the provided gradle file is able to build only for Android, but you are not providing one for jvm only as I guess in that case the build environment is maven.
