Default Chapter 8 Where Am I

When I run the project "Chapter 8 Where Am I" (downloaded code from www.wrox.com) on Eclipse, it says "No Location found". When I tried sending the co-ordinates from the Emulator console -> Location Controls -> Manual, the button "Send" is not responsive. I also loaded a KML file, but it didn't work either. The application says "No location found". How do I see the Lat and Long co-ordinates on the emulator?

Interesting. The first 'Where Am I?' project example only checks for the current location once. In order for the location controls to work, you need to have at least one application that has requested regular updates.

I'd suggest trying one of the later 'Where Am I?' examples from further into the chapter that requests updates (pp 253) and see if that helps.

Hi Reto,
Thanks for your quick reply. The final version of the application "Where am I" finally worked, when tried on an actual device instead of emulator. Emulators are working very strange for this particular application. Now the emulator says "The application has stopped unexpectedly. Please try again." I will keep testing on the actual device.

Default Chapter 8 Where Am I not returning Address

I ran the Where Am I 2 version in Chapter 8. It was supposed to reverse Geocode the address from the lat/log coordinate location, however it is not returning the address. The DDMS indicated the following message:

07-29 08:05:31.131: DEBUG/SntpClient(83): request time failed: java.net.SocketException: Address family not supported by protocol

What can I do to get this to run and return the address as indicated in the example?

I also had the Send button problem and the "No location found" problem. It finally worked with these steps:

1. Add the following code before updateWithNewLocation() call.

   locationManager.requestLocationUpdates(provider, 2000, 10,
         new LocationListener() {
            public void onLocationChanged(Location location) {
            public void onProviderDisabled(String provider) {
            public void onProviderEnabled(String provider) {
            public void onStatusChanged(String provider, int status, Bundle extras) {
2. In DDMS, click the emulator-#### row inside of Devices window. This allowed me to click Send.
3. Scroll down inside of Emulator Control window, and click Send.
4. Start the WhereAmI app to see the Latitude and Longitude!
