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, this will show me the latitude and longitude included in Eclipse!

Does anyone have an idea? I am testing AVD.

I did a test to find out if my location is turned on, but it’s not. I do not know why this is so.

This is my code:

lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 10000, 0, this); mc = mapView.getController(); mc.setZoom(10); myLocation = new MyLocationOverlay(getApplicationContext(), mapView); myLocation.runOnFirstFix(new Runnable() { public void run() { mc.animateTo(myLocation.getMyLocation()); mc.setZoom(10); } }); LocationManager locationManager; String context = Context.LOCATION_SERVICE; locationManager = (LocationManager)getSystemService(context); String provider = LocationManager.GPS_PROVIDER; lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 0, this); Location location = locationManager.getLastKnownLocation(provider); locationManager.getProvider(provider); if(!locationManager.isProviderEnabled(provider)){ locationManager.setTestProviderEnabled(provider, true); } boolean enabled = locationManager.isProviderEnabled(provider); if(enabled){ Toast.makeText(getBaseContext(), "provide enabled : Latitude = " + lat + " Longitude = " + lng+" Altitude = " + alt, Toast.LENGTH_SHORT).show(); } else{ Toast.makeText(getBaseContext(), "provider disabled : Latitude = " + lat + " Longitude = " + lng+" Altitude = " + alt, Toast.LENGTH_SHORT).show(); } if(location!=null){ lat = location.getLatitude();

Thanks!

Answer 1

If your PC / Mac does not have GPS, AVD is not able to detect your location. Test your program on a real device or manually enter values.

Answer 2

Open Virtual Device Manager and click Edit. In the "Hardware" section, click "Create" and add GPS support and change the value to "true". Now run the emulator and open the console. If the emulator boots up to the full type in the telnet localhost 5554 console. When the telnet connection is established, you can insert the following places: geo fix 21.42 42

Answer 3

To add to the existing answers, if you really need to test the functionality of your emulator, you can use the location layout. You can find more details here http://developer.android.com/guide/topics/location/obtaining-user-location.html#MockData .

Keep in mind that for this you must add the necessary permissions (ACCESS_MOCK_LOCATION).

Hope this helps!
