AndroidMobile DevelopmentApps/Applications

This example demonstrates how do I complete address from latitude and logitude in android.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:padding="16sp"
   tools:context=".MainActivity">
   <TextView
      android:text=""
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/textView" />
   <Button
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_marginTop="40dp"
      android:text="Show Address"
      android:id="@+id/btnShowAddress"
      android:layout_centerHorizontal="true" />
   <TextView
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:id="@+id/tvAddress"
      android:layout_alignParentBottom="true"
      android:layout_marginBottom="134dp"
      android:layout_alignParentEnd="true" />
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

import android.support.v7.app.AppCompatActivity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.provider.Settings;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
   Button btnShowAddress;
   TextView tvAddress;
   Location location;
   AppLocationService appLocationService;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      tvAddress = findViewById(R.id.tvAddress);
      appLocationService = new
         AppLocationService(MainActivity.this);
      btnShowAddress = findViewById(R.id.btnShowAddress);
      btnShowAddress.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View arg0) {
            location = appLocationService.getLocation(LocationManager.GPS_PROVIDER);
            double latitude = 13.1000727;
            double longitude = 80.2126274;
            LocationAddress locationAddress = new LocationAddress();
            locationAddress.getAddressFromLocation(latitude, longitude,
               getApplicationContext(), new GeoCodeHandler());
            showSettingsAlert();
         }
         public void showSettingsAlert() {
            AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this);
            alertDialog.setTitle("SETTINGS");
            alertDialog.setMessage("Enable Location
               Provider! Go to settings menu?");
            alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int which) {
                  Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                  MainActivity.this.startActivity(intent);
               }
            });
            alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
               public void onClick(DialogInterface dialog, int which) {
                  dialog.cancel();
               }
            });
            alertDialog.show();
         }
         class GeoCodeHandler extends Handler {
            @Override
            public void handleMessage(Message message) {
               String locationAddress;
               switch (message.what) {
                  case 1:
                     Bundle bundle = message.getData();
                     locationAddress = bundle.getString("address");
                  break;
                  default:
                  locationAddress = null;
               }
               tvAddress.setText(locationAddress);
            }
         }
      });
   }
}

Step 4 − Create a java class (ApplicationService.java) and add the following code

import android.annotation.SuppressLint;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
@SuppressLint("Registered")
public class AppLocationService extends Service implements LocationListener {
   protected LocationManager locationManager;
   Location location;
   private static final long MIN_DISTANCE_FOR_UPDATE = 10;
   private static final long MIN_TIME_FOR_UPDATE = 1000 * 60 * 2;
   public AppLocationService(Context context) {
      locationManager = (LocationManager) context.getSystemService(LOCATION_SERVICE);
   }
   @SuppressLint("MissingPermission")
   public Location getLocation(String provider) {
      if (locationManager.isProviderEnabled(provider)) {
         locationManager.requestLocationUpdates(provider,
            MIN_TIME_FOR_UPDATE,
            MIN_DISTANCE_FOR_UPDATE, this);
         if (locationManager != null) {
            location = locationManager.getLastKnownLocation(provider);
            return location;
         }
      }
      return null;
   }
   @Override
   public void onLocationChanged(Location location) {
   }
   @Override
   public void onProviderDisabled(String provider) {
   }
   @Override
   public void onProviderEnabled(String provider) {
   }
   @Override
   public void onStatusChanged(String provider, int status, Bundle extras) {
   }
   @Override
   public IBinder onBind(Intent arg0) {
      return null;
   }
}

Step 5 − Create a java class (LocationAddress.java) and add the following code −

import android.content.Context;
import android.location.Address;
import android.location.Geocoder;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import java.io.IOException;
import java.util.List;
import java.util.Locale;
class LocationAddress {
   private static final String TAG = "LocationAddress";
   static void getAddressFromLocation(final double latitude,
      final double longitude, final Context context, final Handler
      handler) {
      Thread thread = new Thread() {
         @Override
         public void run() {
            Geocoder geocoder = new Geocoder(context,
               Locale.getDefault());
            String result = null;
            try {
               List<Address> addressList =
                  geocoder.getFromLocation(
                  latitude, longitude, 1);
               if (addressList != null &&
                  addressList.size() > 0) {
                  Address address = addressList.get(0);
                  StringBuilder sb = new
                     StringBuilder();
                  for (int i = 0; i < address.getMaxAddressLineIndex(); i++) {
                     sb.append(address.getAddressLine(i)).append("\n");
                  }
                  sb.append(address.getLocality()).append("\n");
                  sb.append(address.getPostalCode()).append("\n");
                  sb.append(address.getCountryName());
                  result = sb.toString();
               }
            } catch (IOException e) {
               Log.e(TAG, "Unable connect to Geocoder", e);
            } finally {
               Message message = Message.obtain();
               message.setTarget(handler);
               if (result != null) {
                  message.what = 1;
                  Bundle bundle = new Bundle();
                  result = "Latitude: " + latitude + " Longitude: " + longitude +
                     "\n\nAddress:\n" + result;
                  bundle.putString("address", result);
                  message.setData(bundle);
               } else {
                  message.what = 1;
                  Bundle bundle = new Bundle();
                  result = "Latitude: " + latitude + " Longitude: " + longitude +
                     "\n Unable to get address for
                     this lat-long.";
                  bundle.putString("address" , result);
                  message.setData(bundle);
               }
               message.sendToTarget();
            }
         }
      };
      thread.start();
   }
}

Step 6 − Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest
   xmlns:android="http://schemas.android.com/apk/res/android"
   package="app.com.sample">
   <uses-permission
      android:name="android.permission.ACCESS_COARSE_LOCATION" />
   <uses-permission
      android:name="android.permission.ACCESS_FINE_LOCATION"/>
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action
               android:name="android.intent.action.MAIN" />
            <category
               android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run Play Icon icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
