I developed an android app to receive a location and then send a message to collect at a MySQL server via XMPP protocol.
I want to know a differences between using WiFi and 3G/GPRS/EDGE.
If I use WiFi, it can connect to server directly, right? But if I use 3G/GPRS/EDGE, is it possible to send msg to server? If possible, am I set up or need to do something to check the differences mobile connection?
