Need help in GPS location on android

Question

I need a simple code snippet which can do the following. I need a function which can do the following.

1. check if GPS is enabled. If not enabled, then enable it.
2. check for the current location, i.e get longitude and latitude
3. Disable the GPS.

I don't need the continuous location update like LocationListener. Just once in 15 mins is ok. can anybody provide me working code snippet for this?

Answer 1

For enabling GPS:

private void turnGPSOn(){
        String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

        if(!provider.contains("gps")){ //if gps is disabled
            final Intent poke = new Intent();
            poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider"); 
            poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
            poke.setData(Uri.parse("3")); 
            sendBroadcast(poke);
        }
    }

For disabling GPS

 private void turnGPSOff(){
        String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);

        if(provider.contains("gps")){ //if gps is enabled
            final Intent poke = new Intent();
            poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
            poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
            poke.setData(Uri.parse("3")); 
            sendBroadcast(poke);
        }
    }

To check GPS is on or not.

if ( !manager.isProviderEnabled( LocationManager.GPS_PROVIDER ) ) {
        buildAlertMessageNoGps();
    }

For getting current location.

public void getCurrentLocation() {
        LocationManager locationManager;
        String context = Context.LOCATION_SERVICE;
        locationManager = (LocationManager) getSystemService(context);
        Criteria crta = new Criteria();
        crta.setAccuracy(Criteria.ACCURACY_FINE);
        crta.setAltitudeRequired(false);
        crta.setBearingRequired(false);
        crta.setCostAllowed(true);
        crta.setPowerRequirement(Criteria.POWER_LOW);
        String provider = locationManager.getBestProvider(crta, true);

        locationManager.requestLocationUpdates(provider, 1000, 0,
                new LocationListener() {
                    @Override
                    public void onStatusChanged(String provider, int status,
                            Bundle extras) {
                    }

                    @Override
                    public void onProviderEnabled(String provider) {
                    }

                    @Override
                    public void onProviderDisabled(String provider) {
                    }

                    @Override
                    public void onLocationChanged(Location location) {
                        if (location != null) {
                            double lat = location.getLatitude();
                            double lng = location.getLongitude();
                            if (lat != 0.0 && lng != 0.0) {
                                System.out.println("WE GOT THE LOCATION");
                                System.out.println(lat);
                                System.out.println(lng);
                                getAddress();                           
                            }
                        }

                    }

                });
    }
