Call C++ library from Java in Android

Question

Is it possible to call a C++ library from an Android app? If yes, how?

I have zero experience in Android programming (some Java programming experience though) but I would still like to know if this is possible. Given the number of great C++ libraries out there, I would be surprised if it were not possible to call a C++ library from an Android app.

Answer 1

You need to write an Java Native Interface(JNI) to be able to call the native(c/c++) libraries from Android Java code.
The hierarchy is like:

Yes, it's possible. You need to build your C++ library using the Android NDK. The new link https://developer.android.com/ndk/index.html
