compiling opencore-amr codecs for android projects

[GoogleCodeExporter]

I am developing an android app which would use AMR Codecs for Speech, as have 
found suitable for the app. I have downloaded 1) opencore-amr 2) fdk-aac s 
latest source files from here --- 
https://sourceforge.net/projects/opencore-amr/files/

I am wondering how to make use of them having few doubts in compiling them for 
use in android app for speech output to mob speakers.

Firstly I am wondering whether I need to download all 4 provided sub-items 
under the link as required for each other, or only "fdk-aac" / "opencore-amr" 
are sufficient to implement AMR Codecs to android project? As on looking I am 
not finding amr packages in "fdk....

It would be great help for me if someone guides me the way to compile them to 
lib*.so library for Android Jni use?

Moreover Whether the initializing, coding and decoding wrappers were already 
written in downloaded packages or I need to write up a fresh? If so any 
guidance writing would be of great help for me.

Currently I am using G711 / Speex but the speech quality is not as required to 
us. Thus we planned to use AMR Codecs.
