Location Based Services Application

With this example we are going to create a location based services application for Android. Location Based Services are quite popular on mobiles nowadays.

To create a location based services application one should perform the following steps:

These are demonstrated in the code snippet(s) below:

package com.javacodegeeks.android.lbs;

import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class LbsGeocodingActivity extends Activity {

    private static final long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1; // in Meters
    private static final long MINIMUM_TIME_BETWEEN_UPDATES = 1000; // in Milliseconds

    protected LocationManager locationManager;

    protected Button retrieveLocationButton;

    public void onCreate(Bundle savedInstanceState) {



  retrieveLocationButton = (Button) findViewById(R.id.retrieve_location_button);

  locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);





    new MyLocationListener()


    retrieveLocationButton.setOnClickListener(new OnClickListener() {


public void onClick(View v) {




    protected void showCurrentLocation() {

  Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

  if (location != null) {

String message = String.format(

  "Current Location n Longitude: %1$s n Latitude: %2$s",

  location.getLongitude(), location.getLatitude()


Toast.makeText(LbsGeocodingActivity.this, message,




    private class MyLocationListener implements LocationListener {

  public void onLocationChanged(Location location) {

String message = String.format(

  "New Location n Longitude: %1$s n Latitude: %2$s",

  location.getLongitude(), location.getLatitude()


Toast.makeText(LbsGeocodingActivity.this, message, Toast.LENGTH_LONG).show();


  public void onStatusChanged(String s, int i, Bundle b) {

Toast.makeText(LbsGeocodingActivity.this, "Provider status changed",



  public void onProviderDisabled(String s) {


  "Provider disabled by the user. GPS turned off",



  public void onProviderEnabled(String s) {


  "Provider enabled by the user. GPS turned on",





This was an example of an Android location based services application.
