Android - Get Location Only One Time

You can get the last know location using the code below. It gets the location providers and loops over the array backwards. i.e starts with GPS, if no GPS then gets network location. You can call this method whenever you need to get the location.

private double[] getGPS() {
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);  
List<String> providers = lm.getProviders(true);

/* Loop over the array backwards, and if you get an accurate location, then break                 out the loop*/
Location l = null;

for (int i=providers.size()-1; i>=0; i--) {
l = lm.getLastKnownLocation(providers.get(i));
if (l != null) break;
}

double[] gps = new double[2];
if (l != null) {
gps[0] = l.getLatitude();
gps[1] = l.getLongitude();
}
return gps;
}

You can do this with LocationManager.getLastKnownLocation

use LocationManager.requestSingleUpdate()
