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:

Answer 1

To add to the existing answers, if you really need to test the functionality on your emulator you can use mock locations. More you can find here http://developer.android.com/guide/topics/location/obtaining-user-location.html#MockData.

Keep in mind that you have to add the required permission for this (ACCESS_MOCK_LOCATION).

Hope this helps!

Answer 2

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

Answer 3

Unless your PC/Mac has GPS, AVD doesn't have ability to detect your location. Test your program with real device or by entering values manually.
