Hi Chris, I think I will not use the ported Android for any application, my target is just to able to show that Android can run on top of NiosII processor (i.e. get the display), to get into a fully usable Android that would run many applications, I will need another research.
Therefore, what books/literature that I need to read to be able to, as you said, use android as a set of patches for the board's linux? My experience with embedded linux was with linux in Xilinx ML403, so I hope it is not that steep in learning curve for Android. You mentioned "stock android emulator", I am not getting "stock" in your Android emulator, care to explain? Well, actually, there are several that I don't understand, please excuse my ignorant for the time being, such as "kernel's early serial driver", "stock userspace", "constructing an android userspace" and "ADB"?
