This library can be used to create animated 3D User Interfaces. This library is currently under heavy development, so it's not part of the build by default. In order to build this library, you must define BUILD_RENDERSCRIPT=true in your build environment. You will also have to manually edit build/core/prelink-linux-arm.map And add libRS and libRS_jni at the end like this (exact address may change.) libRS.so 0x9A100000 libRS_jni.so 0x9A000000
