AGPS doesn't use WiFi. It uses precomputed Almanac/Ephemeris data so the GPS receiver has a better idea which satellites to expect, and where. That data needs to be refreshed every x days (usually 3 to 7), and is injected into the GPS receiver management software. I don't think that software is exposed to Android.
