Create my own disk for Android emulator

I need to work on the internals of android, e开发者_开发知识库specially create and test new kernel modules, native libraries and native application. Thus I need to create my own android disk image to use on android emulator. I'm looking for the source code for this operation, with all the tools and build programs to have a fully complete image with all standard applications. Does anyone know where I can found this (most of the source distribution are without build files, or dedicated to one platform) ?

Just get the source and build it
