That means two things: not every Android phone has assistance data support and that you can do this as part of the porting efforts which is a completely different scale of task. If you have an external A-GPS receiver (USB, Bluetooth) you can use so called "mock" location provider - create your own provider, utilize TCP/IP to exchange data with your server, use Android's location providers, etc. Looks like a perfect approach for any experimental thing.
