Apps How to get current location of user without using gps or internet in android?

[Samitha Chathuranga]

This question is directly related to the same prevailing stackoverflow question at "Android: get current location of user without using gps or internet" where the accepted answer is actually not answering the question. I should be able to get the location of the device via network provider but not with GPS or internet. Following is the accepted answer in that question. (The following code parts should be included in the onCreate() method)

// Acquire a reference to the system Location Manager
LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

// Define a listener that responds to location updates
LocationListener locationListener = new LocationListener() {
    public void onLocationChanged(Location location) {
      // Called when a new location is found by the network location provider.
      makeUseOfNewLocation(location);
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {}

    public void onProviderEnabled(String provider) {}

    public void onProviderDisabled(String provider) {}
  };

// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

I changed the above code given in the linked answer as following but no success.

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final TextView txtView = (TextView) findViewById(R.id.tv1);
    txtView.setText("ayyo samitha");
    ////

    // Acquire a reference to the system Location Manager
    LocationManager locationManager;
   locationManager= (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);

    // Define a listener that responds to location updates
    LocationListener locationListener = new LocationListener() {
        public void onLocationChanged(Location location) {
            // Called when a new location is found by the network location provider.
            makeUseOfNewLocation(location);

        }

        private void makeUseOfNewLocation(Location location) {
            txtView.setText("sam came in");
            txtView.append(location.toString());
        }

        public void onStatusChanged(String provider, int status, Bundle extras) {}

        public void onProviderEnabled(String provider) {
           // makeUseOfNewLocation(location);
        }

        public void onProviderDisabled(String provider) {}
    };

  // Register the listener with the Location Manager to receive location updates
    if (locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
        locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);
    }

}

How to accomplish what I want by correcting above code or any other method? Can somebody please help me.

Do you have this in manifest?

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

You are trying to instantiate a new locationlistener which is not allowed because it is not a class. LocationListener is an interface and has to be implemented by the activity. Add "implements LocationListener" to your activity declaration and eclipse (or Studio) will then ask you to add the unimplemented methods.
