Android getting best location

I want the exact location of user. So I created two listeners as:

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, mGPSListener);
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, mNetworkListener);

I am listening for location updates from both the network and gps providers and wanted to check the accurary of locations obtained by both so that I can pick the accurate location. I just want to ask am I using the right way of acheiving that...??? if not, please provide some guideline how to do this...???

My example code is:

if(MyGPSListener.currentLocation != null) {
        if(MyNetworkListener.currentLocation != null) {
            if(MyGPSListener.currentLocation.getAccuracy() <= MyNetworkListener.currentLocation.getAccuracy()) {
                useGPSLocation();

            }
            else if(MyGPSListener.currentLocation.getAccuracy() > MyNetworkListener.currentLocation.getAccuracy()) {
                useNetworkLocation();

            }
        }
        else {
            useGPSLocation();

        }

    }
    else if(MyNetworkListener.currentLocation != null){
        useNetworkLocation();

    }
Solution

  • You should take a look at: http://developer.android.com/guide/topics/location/obtaining-user-location.html Especially the function: isBetterLocation

    I would probably use something like the isBetterLocation. Since it's actually quite important to see how old the location updates are. At least if you really want to know where the user is know and not where the user were.

    But you can surely implement a time check in your own function which you described.
