This is the same question, as How to add a shared library to my APK? but i want to know how to do the same with Android Studio, not Eclipse.
There is very obscure documentation on this topic: https://developer.android.com/ndk/guides/prebuilts.html It says roughly "Give the module a name, change Android.mk" but there is no info on what is a module, how to find it or add it, and where is the Android.mk.
