In my experience, Android won't acquire a location just because your Wi-Fi will inherit that to the Emulator.

You need to follow some steps:

  1. Be sure to have the following permissions in your Android Manifest:

    android.permission.INTERNET

    android.permission.ACCESS_NETWORK_STATE

    android.permission.ACCESS_COARSE_LOCATION

    android.permission.ACCESS_FINE_LOCATION

    android.permission.ACCESS_LOCATION_EXTRA_COMMANDS

    android.permission.ACCESS_MOCK_LOCATION

    android.permission.CHANGE_WIFI_STATE

    android.permission.ACCESS_WIFI_STATE

  2. Be sure to have the maps library in your Application tag:

    <application android:icon="@drawable/ic_launcher" >
        <uses-library android:name="com.google.android.maps" />
</application>

  3. Be sure to have a valid Maps API Key in your MapView in your /layout/map.xml file.

  4. Because you are not running your App on an actual device, the only way to send different locations to your App is to push a MOCK LOCATION. To do so, simply Launch your App in the Emulator, go to the DDMS perspective in Eclipse IDE, and look for the options on the left (reset the DDMS perspective if you can't find them). It should look like this:

enter image description here

Select the Emulator Name under the "Devices" Tab, then you can send Latitude and Longitude coordinates using the "Location Controls".

When you are done developing and testing, be sure to remove the ACCESS_MOCK_LOCATION permission and to test the location detection on an actual phone or tablet with either GPS, aGPS chip or Cellular/Wifi Network.

When you run a mobile application on desktop simulator, which doesn't have GPS in it, you will get some fixed location every time. To get real GPS coordinates you need to install it in a android device and test it.

** Update **

If you are having the same problem on your phone too, then your phone GPS is probably switched off, which you need to turn on, or phone is using Wifi to get a fix on its location.

Just a thought, is the phone getting the GPS location through your home wifi network rather than the phone's GPS? Might explain why they both give the same wrong value.
