I've been looking for a while now for any java library that allows me to encode and decode a PCM-AMR audio stream that is sent through a TCP socket connection. Without having to use Android's JNI.
Is there anything that can help me?
In the worst case scenario. How can I do it using any C++ library with JNI? (any reference of how to use ffmpeg with JNI will be appreciated)
Hope you can help me.
Note that pcm usually means RAW and note encoded downstream of the microphone (hardware ) that generated the signal. amr-nb, amr-wb are encoded. So, i suggest that you resolve exactly what type of bytestream that you have on the socket..
Then, IMO , on android, ffmpeg libs provide robust , wide choice of TO/FROM Codecs and the way to convert.
See any of the main github [android-ffmpeg] projects, acouple of which are below:

Its a bit of learn curve to sort thru all the JNI/Android stuff. IMO if you are doing low-level media stuff like this , you have little alternate to mastering JNI.
