Accessing GPS is not working. Application uses network to getting location

My app doesnt want to use GPS and using network to get location instead. I checked that by analysing latitude and longtitude, they're a little bit random (like network location).

If I use another app using GPS (e.g Endomondo Sports tracker) I see characteristic mark, which means, that GPS is currently working:

enter image description here

When I launch my application, there's no mark at all.

I'm using following code (code by Lars Vogella, Source:

import android.content.Context;
import android.location.Criteria;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.Toast;

public class ShowLocationActivity extends Activity implements LocationListener {
private TextView latituteField;
private TextView longitudeField;
private LocationManager locationManager;
private String provider;

/** Called when the activity is first created. */

public void onCreate(Bundle savedInstanceState) {
latituteField = (TextView) findViewById(;
longitudeField = (TextView) findViewById(;

// Get the location manager
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// Define the criteria how to select the locatioin provider -> use
// default
Criteria criteria = new Criteria();
provider = locationManager.getBestProvider(criteria, false);
Location location = locationManager.getLastKnownLocation(provider);

// Initialize the location fields
if (location != null) {
System.out.println("Provider " + provider + " has been selected.");
} else {
latituteField.setText("Location not available");
longitudeField.setText("Location not available");

/* Request updates at startup */
protected void onResume() {
locationManager.requestLocationUpdates(provider, 400, 1, this);

/* Remove the locationlistener updates when Activity is paused */
protected void onPause() {

public void onLocationChanged(Location location) {
int lat = (int) (location.getLatitude());
int lng = (int) (location.getLongitude());

public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub


public void onProviderEnabled(String provider) {
Toast.makeText(this, "Enabled new provider " + provider,


public void onProviderDisabled(String provider) {
Toast.makeText(this, "Disabled provider " + provider,

Of course I added permissions in

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

Any ideas?

Solution: you can use GPS instead of selecting best provider by deciding criteria.

Example, Replace:

locationManager.requestLocationUpdates(provider, 400, 1, this);


locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 400, 1, this);


Depending on your application's use case, you have to choose a specific location provider i.e. LocationManager.GPS_PROVIDER or LocationManager.NETWORK_PROVIDER

Alternatively, you can provide some input criteria such as accuracy, power requirement, monetary cost, and so on, and let Android decide a closest match location provider

    // Retrieve a list of location providers that have fine accuracy, no monetary cost, etc
Criteria criteria = new Criteria();
String providerName = locManager.getBestProvider(criteria, true);
//and then you can make location update request with selected best provider
locationManager.requestLocationUpdates(provider, 400, 1, this); 

Have a look at how to use locationmanager , how to specify Criteria and how getBestProvider method works for reference
