By default there is no location (latitude and longitude) set in the Android Emulator, so you have to set this – before you are able to work with GPS location coordinates. Here is how you do it:

1. Start your Android Emulator
2. Open your Terminal or Command Prompt (CMD)
3. Connect to the Emulator:

   telnet localhost <port>
   

   Note: You can see the port number in the title bar of the running Android Emulator

4. Enter the location coordinates you wish to test with:

   geo fix <longitude> <latitude>
