 ## Building
 
+Since there are some [issues](https://stackoverflow.com/questions/61410231/android-studio-cannot-resolve-symbols-for-composite-includebuild-dependency-in-j)
+with Android Studio and [composite builds](https://docs.gradle.org/current/userguide/composite_builds.html),

+or by using Android Studio 3.5.3.
