Android studio ; jni.h not found

sebseb24 :

I'm trying to build a GStreamer app using Android Studio on windows using the tutorials on their website, but, as already mentioned in other questions, the tutorials are not up-to-date nor seems to work on Android Studio. I've followed the tutorial proposed by Eduardo Fernando at : Gstreamer examples in Android Studio, but it won't build since I can't manage to fix the issue of the jni.h file not found.

> Build command failed.

I executed the javah command, but the generated .h cannot find the #include either.

I tried the ndk-build command, but it will stop saying the jni.h file is missing.

Any advices on how I could link the jni.h file to the project?

This is potentially a problem with the r16 changes in the Android NDK which are fixed upstream by the following commit

The problem is that the NDK moved the header files around into a unified structure and thus broke any user expecting headers in the old locations.
