2 nd App Name: LocateFriendMap
Function:
1) show your current location in map;
2) calculate distance between your friends and yourself;
3) select your friend’s location and show in map;
4) display google map navigation to lead you to meet friend.
Operation Manual:
1)Setup your own username and password in the first time, then use it to logon next time; if you forget your password, simply setup another one.
2)There is a switch button to allow you to select "MyLocation" or "FindFriend" to show your location on map or show the distance between you and your friends.
3)As you select "MyLocation", it will show your map and you can press "Show Me To Friend" or "Cancel to Show Me" button.
4)As you select "FindFriend", it will show a list of your friends; as you select a friend, it will show a map between you and your friend, and you can also use "Navigation" button to call the google map navigation function.
5)To remind to use back arrow button "<" to go back to previous screen.
6)If you get trouble on map location display, you should check whether your phone GPS location function is active (maybe display your last location, but not current location), or go to out-door to get good GPS signal.
