Hi All,
I am trying to get location update and followed some good tutorial.
Initially, onLocationChanged was called frequently. But after I made
certain simple modification, it started not working today. I am
copying my code below. Can anyone let me know the problem? The GPS
service is running all the time. I am working on an Atrix phone.
Thanks!
