im wondering how does WeChat's Shake works ? not matter of sensor, i mean how does it find people in a circle radius ? is it a modifie version of asmack which sends last known latitude,longitude with each ping? im currently using a modified version of asmack in favour of FileTransfer, i also have maps on my application, am i able to use it without too much effort? thanks alot
Speculation:
They send your latitude & longitude to their server, which queries for other users in a specified radius and returns the results to your device.
