android gps current location

Question

I want to display my current location, but it shows me the latitude and longitude that I set on the command line! If I don't set the parameters on the command line, it shows me the latitude and longitude included in Eclipse!

Is there any one who has an idea about that? I'm testing with AVD.

I made a test to see if my location is enabled, but it isn't. I'm not sure why that is the case.

This is my code:

Open your Virtual Devices manager and klick Edit. At the section Hardware click New and add GPS support and change the value to true. Now start the emulator and open a console. If the emulator is boot up complete type in the console telnet localhost 5554. When the telnet connection is established you can put in locations like this: geo fix 21.42 42
