How to find the latitude and longitude from address in Android?

AndroidMobile DevelopmentApps/Applications

This example demonstrates how do I find the latitude and longitude from address 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:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Enter Address"
      android:id="@+id/textViewAddress"
      android:textAppearance="?android:attr/textAppearanceMedium"
      android:layout_alignParentStart="true" />
   <EditText
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:id="@+id/editTextAddress"
      android:layout_alignParentTop="true"
      android:layout_toEndOf="@+id/textViewAddress"
      android:singleLine="true"
      android:text="" />
   <Button
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Show Lat/Long"
      android:id="@+id/addressButton"
      android:layout_below="@+id/textViewAddress"
      android:layout_toEndOf="@+id/textViewAddress"
      android:layout_marginTop="50dp" />
   <TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textAppearance="?android:attr/textAppearanceLarge"
      android:text=""
      android:id="@+id/latLongTV"
      android:layout_centerVertical="true"
      android:layout_toEndOf="@+id/textViewAddress" />
</RelativeLayout>

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

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
   Button addressButton;
   TextView textViewAddress;
   TextView textViewLatLong;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      textViewAddress = findViewById(R.id.textViewAddress);
      textViewLatLong = findViewById(R.id.latLongTV);
      addressButton = findViewById(R.id.addressButton);
      addressButton.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View arg0) {
            EditText editText = findViewById(R.id.editTextAddress);
            String address = editText.getText().toString();
            GeoCodingLocation locationAddress = new GeoCodingLocation();
            locationAddress.getAddressFromLocation(address, getApplicationContext(), new
               GeoCoderHandler());
         }
      });
   }
   private class GeoCoderHandler 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;
         }
         textViewLatLong.setText(locationAddress);
      }
   }
}

Step 4 − Create a java class (GeoCodeLocation.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 GeoCodeLocation {
   private static final String TAG = "GeoCodeLocation";
   public static void getAddressFromLocation(final String
   locationAddress,
   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 addressList = geocoder.getFromLocationName(locationAddress, 1);
               if (addressList != null && addressList.size() > 0) {
                  Address address = (Address)
                     addressList.get(0);
                  StringBuilder sb = new StringBuilder();
                  sb.append(address.getLatitude()).append("\n");
                  sb.append(address.getLongitude()).append("\n");
                  result = sb.toString();
               }
            } catch (IOException e) {
               Log.e(TAG, "Unable to connect to Geocoder", e);
            } finally {
               Message message = Message.obtain();
               message.setTarget(handler);
               if (result != null) {
                  message.what = 1;
                  Bundle bundle = new Bundle();
                  result = "Address: " + locationAddress +
                     "\n\nLatitude and Longitude
                     :\n" + result;
                  bundle.putString("address", result);
                  message.setData(bundle);
               } else {
                  message.what = 1;
                  Bundle bundle = new Bundle();
                  result = "Address: " + locationAddress +
                     "\n Unable to get Latitude and
                     Longitude for this address location.";
                  bundle.putString("address", result);
                  message.setData(bundle);
               }
               message.sendToTarget();
            }
         }
      };
      thread.start();
   }
}

Step 5 − 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_FINE_LOCATION" />
   <uses-permission
      android:name="android.permission.INTERNET" />
   <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 −
