Android - Get Location Only One Time

Question

i need to get the current user location on an android app, so i've read some tutorials and samples on the web, but i see that in all the examples, the location is retrived from a "onLocationChange" that mean that every time the location change, the code in the "onLocationChange" is executed.

i need only to get the user location at the moment the app is started.

Thanks for your help!

Answer 1

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
