Hi guys,
I've just finished to migrate the andoid (non-native) demo project to Gradle / Android Studio.
basically, everything is in app/src/main and C/C++ files are in app/src/jni
you can either build the project from command-line.
1) build jni stuff (goto app/src folder and call ndk-build)
2) install apk (goto root project folder and call ./gradlew installRelease)
or you can import the project in Android Studio (don't directly Open the project, select Import)
If you need help to migrate your existing projects, don't hesitate to ask here or in the forum.
