configure/customize an AVD

In the AVD manager for Android in ubuntu I can specify the size of the SD card storage, the "skin", the screen resolution, and certain hardware specs.

But what if I wanted to make something like a new android ROM image or build to use rahter than the given or coming options in target, is that possible.

Is there a step-by-step document describing how to configu开发者_运维知识库re/customize an AVD to that level of detail?

Thanks in advance. kash

Download the source code. Make you customizations. Build it. Run the custom OS on your emulator.
