You might look at android/ffmpeg/x264 project as an example. x264 is not ogg/vorbis, but it is a clear example of linking ffmpeg with adjunct libs in android build and link scenario.
Note: this will take quite a bit of time to work thru.
If you understand the example of building with x264, then you should be able to swap in obb/vorbis libs in place of x264 and get it all to link on an android build.
This assumes you are good with the NDK and cross toolchains and with git projects and sub-modules (x264 , ogg, vorbis)
