This android tutorial is to help learn location based service in android platform. Knowing the current location in an android mobile will pave the way for developing many innovative Android apps to solve peoples daily problem. For developing location aware application in android, it needs location providers. There are two types of location providers,
Any one of the above providers is enough to get current location of the user or user’s device. But, it is recommended to use both providers as they both have different advantages. Because, GPS provider will take time to get location at indoor area. And, the Network Location Provider will not get location when the network connectivity is poor.
To access current location information through location providers, we need to set permissions with android manifest file.
<manifest ... >
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission. ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
</manifest>
ACCESS_COARSE_LOCATION is used when we use network location provider for our Android app. But, ACCESS_FINE_LOCATION is providing permission for both providers. INTERNET permission is must for the use of network provider.
For any background Android Service, we need to get reference for using it. Similarly, location service reference will be created using getSystemService() method. This reference will be added with the newly created LocationManager instance as follows.
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
After creating the location service reference, location updates are requested using requestLocationUpdates() method of LocationManager. For this function, we need to send the type of location provider, number of seconds, distance and the LocationListener object over which the location to be updated.
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
LocationListener will be notified based on the distance interval specified or the number seconds.
This example provides current location update using GPS provider. Entire Android app code is as follows,
package com.javapapers.android.geolocationfinder;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.widget.TextView;
import android.util.Log;
public class MainActivity extends Activity implements LocationListener{
protected LocationManager locationManager;
protected LocationListener locationListener;
protected Context context;
TextView txtLat;
String lat;
String provider;
protected String latitude,longitude;
protected boolean gps_enabled,network_enabled;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtLat = (TextView) findViewById(R.id.textview1);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
}
@Override
public void onLocationChanged(Location location) {
txtLat = (TextView) findViewById(R.id.textview1);
txtLat.setText("Latitude:" + location.getLatitude() + ", Longitude:" + location.getLongitude());
}
@Override
public void onProviderDisabled(String provider) {
Log.d("Latitude","disable");
}
@Override
public void onProviderEnabled(String provider) {
Log.d("Latitude","enable");
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d("Latitude","status");
}
}
XML files for layout and android manifest are as shown below
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:text="@string/hello_world" />
</RelativeLayout>
<?xml version="1.0" encoding="utf-8"?>

android:theme="@style/AppBaseTheme" >
<activity

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
Note: If you are running this Android app with emulator, you need to send the latitude and longitude explicitly for the emulator.

Hi,
How can i scan barcodes in android application!
yes u can use barcode scan u will find source code for barcode scan check it in github repository once i used zxing(a barcode scanner Engine)
[…] we studied about how to get current geographic location using an android application. That Android app will return latitude and longitude pair to represent current location. Instead of […]
Does this app need any type of internet ???
I run the above code.but only hello world is displayed.no location data.Please specify the code for activity main.xml to display the location
Simple and Efficient..
nice tutorial….
i am new to android ,i tried the same but when i run it shows me “unfortunately app has stopped working” please help me fix this.
Very helpful!
Very nice tutorial.Please tell me how can we use these coordinates to locate this position in the map .thank you
First you need to display the map fragment (https://javapapers.com/android/show-map-in-android/), then you need to tile these coordinates on top of it by using location service / activity.
I will post a tutorial for this exact topic very soon.
hi..!!!
its working fine when im using emulator,but it is showing nothing when im uing it in my phone..!!
just hello world is outputed on the screen..!!
Hi,
How can i get output in phone instead of emulator because it works in emulator.
i am new to android ,i tried the same but when i run it shows me “unfortunately app has stopped working” please help me fix this
thanks alot for helping by this tutorial..
can u tell me hopw to find the direction and KMS using android google maps
I’m new to android as well and was getting the same error. What solved it was that I tried it on device and not the emulator. The emulator kept giving me error even after sending values through DDMS.
second mistake i made was i changed the name of the package and forgot to change the names in manifest. Just make sure you are not doing the same.
Worked instantly.. Thanks for the tutorial..
how to get date and time from internet in android

its working fine in emulator kindly intimate how to display in tab
Have you posted any tutorial for network based on network location service yet?
Please give URL,
Thank You
very simple dear
1-install eclipse.
2-After debug the program u will the .apk file

3-Copy the .apk file and put inside ur mobile and run it…
dear Joe when i install apk file in Phone only
hello world message is display not lat n long find
i an new in android apps please help and suggest how to call .NET web service in this with post and get method
I think you are testing code by emulator. If yes, you need to set lattitude and longtitude manually. Its also said by author at the end of this tutorial. Please look at that and then try. Its running good for me.
great job amazing work simple easy yet effective
Nice one.
But This one is not working inside the room.we need the display the current location using network provider.
Thanks, great tutorial, best i found and works like a charm.
Can you publish one explaning GoogleMaps ?
Regards

hi , i manually added langitute and logitute .but nothing showing on my emulator..
it says only
latitute=Location not available
longitude=Location not available
This code is not working inside the room.we need the display the current location using network provider.
Great tutorial. I keep having the same problem with certain apps I write – in that they work on the emulator, but give an error on my cell phone.
App starts up then suddenly gives the message “Unfortunately, GPSapp has stopped”
Any ideas would be greatly appreciated

Apologies – I see this question has been raised a few times before. I have tried the suggestions above (eg make sure package name is same in program and manifest etc) but still no joy. Thanks Bryn
Bryn,
There can be numerous reasons to a crash. Best way to find the reason is to get the LogCat logs when it crashes. Plug the phone in USB and set it as target device. Then launch the app in phone and you can get the logs on this error.
all are incredible !
For anyone who shows “Hello World” on the mobile phone instead current location change MainActivity.java to following:
package com.javapapers.android.geolocationfinder;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.widget.TextView;
import android.util.Log;
public class MainActivity extends Activity implements LocationListener {
// The minimum distance to change Updates in meters
private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 10; // 10 meters
// The minimum time between updates in milliseconds
private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute
protected LocationManager locationManager;
protected Context context;
protected boolean gps_enabled, network_enabled;
TextView txtLat;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
txtLat = (TextView) findViewById(R.id.textview1);
locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// getting GPS status
gps_enabled = locationManager
.isProviderEnabled(LocationManager.GPS_PROVIDER);
// getting network status
network_enabled = locationManager
.isProviderEnabled(LocationManager.NETWORK_PROVIDER);
if (gps_enabled) {
locationManager.requestLocationUpdates(
LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
} else if (network_enabled) {
locationManager.requestLocationUpdates(
LocationManager.NETWORK_PROVIDER, MIN_TIME_BW_UPDATES,
MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
};
}
@Override
public void onLocationChanged(Location location) {
txtLat = (TextView) findViewById(R.id.textview1);
txtLat.setText(“Latitude:” + location.getLatitude() + “, Longitude:”
+ location.getLongitude());
}
@Override
public void onProviderDisabled(String provider) {
Log.d(“Latitude”, “disable”);
}
@Override
public void onProviderEnabled(String provider) {
Log.d(“Latitude”, “enable”);
}
@Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d(“Latitude”, “status”);
}
}
In my code, onLocationChanged() method is not getting called while I am running my app on mobile. What may be the reason behind it?
How to send latitude and longitude to android emulator
Open DDMS perspective in Eclipse (Window -> Open Perspective)
Select your emulator device
Select the tab named emulator control
In ‘Location Controls’ panel, ‘Manual’ tab, give the Longitude and Latitude as input and ‘Send’.
For this steps we simple load a .kml file to emulator that will take a automatically from the LOCATION CONTOLS…
Thanks for a nice tutorial.Kindly help me on how to serve the obtained coordinates(latitudes&longitudes) to MySQL database.
Thank you sir…
this is very important to me. Pleas carry on your tutorials ahead.
I have seen some applications being able to retrieve the VLR Global title , something like the Node Number you are latched on , for example in Jordan it will be something like 96279123456 , but from the API i am not able to get to that level , any idea how could that have been done ?
Can anyone please help me on automatic storage of the obtained coordinates (latitude &longitude…from this tutorial)in mySQL database, this should be done without requiring the phone user to press a send button.
May God bless you for your kind assistance.
Happy coding!!
Friends,is there no one who can give a hint on this??? Plz your assistance or some links/books to refer to will help me a lot.

Its working fine,but we need only city list within 100km from current location. So how to get that. Can u help me????
the application is stopped its not even opening
nice tutorial sir
it will help me lot
I could not get the 2 parameters (time and distance) used in requestLocationUpdates method. What I could understand is that after x time or x meters request for the user location but why both?
And if we are giving both parameter then, which would be used(time interval or distance)?
Also OnLocationChanged method would be called only when we requestLocation or will it be triggered every time user changes his location without even calling requestLocation method?
Please clarify my doubts.
on launching application helloworld only displaying
onlocation changed method is nt calling when i run this application i kept debug statements to confirm that pls give solution
Helpful man and thx
I am install the app on my phone, but only it only displaying –hello word– no latitude, no longetutide
