I wrote a program to show my current location, Address etc in android phone. The API used is Android 2.2. Previously it worked fine in a MTS CDMA phone. It had an API of Android 2.3. It also works fine in emulator. Now. I have bought a Sony Ericsson Xperia Minipro and it also has Android 2.3. But the program will run on it. But the edit texts will not show anything. I use edit texts to display the values. They are not updated by the program at all. What can be the problem? Same program works fine in emulator and it shows location! Please help. I can paste the code below
public class TravelGuide extends Activity {
private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES=1;
private static final long MINIMUM_TIME_BETWEEN_UPDATES=1000;
StringBuilder strReturnedAddress;
List<Address> addresses;
protected LocationManager locationManager;
static String videoId;
Double lat;
Double longd;
Address returnedAddress;
private final LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
//Double latitude = location.getLatitude();
//Double longitude = location.getLongitude();
}
