as abhijit said, easier logcat error, because error gave 1 displayed android, exception raised in code.
if had guess, maybe userstatus activity not declared in manifest.
edit: way, make sure gps enabled on device test on. might want verify programatically in way on android developers website, , open location settings if not enabled. check out here.
