1. access points


I have some code that uses a network connection .. I create a
connection by calling openConnection() on a URL object.

Is there any documentation that explains how this process works? Which
access point is being used? When that access point becomes invalid,
will it automatically switch to another accespoint? etc.

I would like to use only WIFI access points and otherwise fail even
tho 3G or GPRS could be available, is that possible?
