How to get current GPS location programmatically on Android?


This example demonstrates how do I get current GPS location programmatically 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

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:layout_margin="16dp"
   android:gravity="center_horizontal"
   android:orientation="vertical">
   <TextView
      android:id="@+id/location"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="Current GPS Loaction"
      android:textSize="24sp"
      android:textStyle="bold" />
   <Button
      android:id="@+id/getLocation"
      android:text="Get location"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" />
</LinearLayout>

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

import android.content.pm.PackageManager;
import android.location.Location;
import android.os.Bundle;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import com.google.android.gms.location.FusedLocationProviderClient;
import com.google.android.gms.location.LocationServices;
import com.google.android.gms.tasks.OnSuccessListener;
import static android.Manifest.permission.ACCESS_FINE_LOCATION;
public class MainActivity extends AppCompatActivity {
   private FusedLocationProviderClient client;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      requestPermission();
      client = LocationServices.getFusedLocationProviderClient(this);
      Button button = findViewById(R.id.getLocation);
      button.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            if (ActivityCompat.checkSelfPermission(MainActivity.this, ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED ) {
               return;
            }
            client.getLastLocation().addOnSuccessListener(MainActivity.this, new OnSuccessListener() {
               @Override
               public void onSuccess(Location location) {
                  if (location != null) {
                     TextView textView = findViewById(R.id.location);
                     textView.setText(location.toString());
                  }
               }
            });
         }
      });
   }
   private void requestPermission(){
      ActivityCompat.requestPermissions(this, new String[]{ACCESS_FINE_LOCATION}, 1);
   }
}

Step 4 − 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" />
      <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  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
