event…….example when application is double clicked ,dialer gets opened
and when same application is single clicked , should get open...is it
possible…if yes….kindly help me with the code of the same…..
Other problems….

I have done coding to retrieve the latitude and longitude using gps
but its not working....location is showing null value and finally it
do not have any values of latitude and longitude.
I have tried passing the values from Emulator control and also through
command line using "telnet local host 5554(device name)".....

Also same is the case with Google maps ,I have tried to access Google
maps but its not working via coding….i do have registered for Maps
key…..but I am able to access Google maps application from emulator
which is default present on emulator…I think so there is problem with
the code….

public class gps extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LocationManager locationManager;
locationManager =
(LocationManager)getSystemService(Context.LOCATION_SERVICE);
Location location =
locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

updateWithNewLocation(location);
}
/** Update UI with a new location */
private void updateWithNewLocation(Location location) {
TextView myLocationText =
(TextView)findViewById(R.id.myLocationText);

String latLongString;

if (location != null) {
double lat = location.getLatitude();
double lng = location.getLongitude();
latLongString = "Lat:" + lat + "\nLong:" + lng;
