Start the Emulator
Start a command prompt
Then, type, o localhost 5554
This connects the telnet client to the android emulator (assuming emulator is running locally listening on port 5554. Else this connection fails)
geo fix 79.000000 13.000000 (or your latitude and longitude)
This sends the location change signal to the emulator.
NOTE: This is useful for applications built using Location APIs in Android and need to work with changes in location
