Thank you for the reply. Is the FriendFinder your contest entry? Looks very good, man. If you posted it as a tutorial and not as your contest entry, I really wonder how you come up with such wonderful tutorials. You must have spent a lot of time experimenting because I find the documentation for Android very insufficient.

tv_sathish wrote:2. When I start the FriendFinder, and debug the program, my GPS location is not set, but it still shows a distance of 2.xxx km, how is this possible and later it increases - strangely when I switch the window and come back, the distance starts decreasing, and then again increases if I do not switch for a minute or two. How do I verify if the GPS values of my location are indeed retrieved. Does the LocationManager retrieve GPS of your current geographical co-ordinates? Then it must have shown a lot of distance as I entered US co-ordinates for the contact and I am in India, but it was just exponentially growing in units of 1. I hope Internet connection is required for GPS to work right, but then how do I ensure that "myLocationManager.getCurrentLocation("gps")" returns correct GPS value?

FOTA_UPDATE_ACTION Broadcast Action: Trigger the download and eventual installation of an over-the-air (OTA) operating system update.

tv_sathish wrote:5. Does the Android Maps package use Google Map API inturn? I opened the class files inside the JAR, but could not find any reference to any external class? Is there some tutorial on Google Map API? Can we use it in conjuction with Android SDK? (As an aside, which package helps you to connect to Internet and browse in Android SDK?)
