In this blog I explaining to get current location as well as find update location. In android have two types to get location

1.   GPS Location Provider

2.   Network Location Provider

Network Provider is fast is compare than GPS. GPS is very slow and its drain more battery. Network Provider depend on cell tower and it does not return accurate address but GPS provider give us accurate address.

Here I am creating a sample which give us accurate current address as well as whenever location updates it also provide updates location accurately.

1.   First of all we have need to allow permission in manifest file to access GPS. Add following permission in manifest.xml file

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

2.   Add Textview Control in activity.xml file 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">
    <TextView
        android:id="@+id/tvFullLocation"
        android:layout_gravity="center"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</LinearLayout>

3. Add below code in MainActivity.class 

packag com.example.msclient009.androidlocation; 
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.location.Address;
import android.location.Geocoder;
import android.location.Location;

import android.location.LocationManager;

import java.util.List;
import java.util.Locale;
public class MainActivity extends Activity implements LocationListener {
    LocationManager locationManager;
    //Geocoding is the process of transforming a street address or other description of a location into a // (latitude, longitude) coordinate.
    Geocoder geocoder;
    TextView textView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = (TextView) findViewById(R.id.tvFullLocation);
        //  GeoCoder and Location Manager
        geocoder = new Geocoder(getApplicationContext(), Locale.getDefault());
        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        // check GPS is enable or not
        boolean statusOfGPS = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
        if (statusOfGPS) {
            try {
                // apply for get current address
                locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
             // We can get address according to  minimum requirement such as on update distance 50 meters
                // or after duration 10 minute 
            // locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100000, 50, this);
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
    }
 
    public void updateCurrentLocation(final String text) {
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                textView.setText("Location -: " + text);
            }
        });
    }
    @Override
    public void onLocationChanged(final Location location) {
        try {
            // When location change return Location reference and we can get latitude and longitude                                // of  current address
            // GeoCoder return all address of location
   List<Address> addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 10);
            if (addresses != null) {
                if (addresses.size() > 0) {
                    Address address = addresses.get(0);
                    String addressText = String.format(
                            "%s, %s, %s",
                            // If there's a street address, add it
                            address.getMaxAddressLineIndex() > 0 ? address
                                    .getAddressLine(0) : "",
                            // Locality is usually a city
                            address.getLocality(),
                            // The country of the address
                            address.getCountryName());
                    updateCurrentLocation(addressText); 
                }
            } 
        } catch (Exception ex) {
        }
    }
 
    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) { 
    } 
    @Override
    public void onProviderEnabled(String provider) {
    }
    @Override
    public void onProviderDisabled(String provider) {
    }
}

4.   Now run your application. See Output of your current address
