Download the Android NDK (latest release as of now is r5). Follow the instructions on the website. To make things easier, add the directory where you unpacked the NDK to your path:
`export PATH="$PATH:<path to your ndk directory"
You use the ndk-build script provided there to compile everything needed.
From the project root, use these steps:
$ cd jni
$ ndk-build
Generated headers for the dependent libraries have been checked in so you should not need to reconfigure them. If you do for some reason, you may follow these instructions.
WARNING: This will likely break things as sources have been customized to work on Android.
Setup some environment variables to make this easier:
export JDK_HOME=<path your JDK directory>
