How to show current location on a google map on Android?
This example demonstrates how do I show current location on a google map on 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"?> <fragment xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/myMap" android:name="com.google.android.gms.maps.SupportMapFragment" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity" />
Step 3 – Add the following dependency in the build.gradle (Module: app)
implementation 'com.google.android.gms:play-services-maps:17.0.0' implementation 'com.google.android.gms:play-services-location:17.0.0'
Step 4 − Add the following code to src/MainActivity.java
import android.Manifest; import android.content.pm.PackageManager; import android.location.Location; import android.os.Bundle; import android.widget.Toast; import com.google.android.gms.maps.CameraUpdateFactory; import com.google.android.gms.maps.SupportMapFragment; import com.google.android.gms.location.FusedLocationProviderClient; import com.google.android.gms.location.LocationServices; import com.google.android.gms.maps.GoogleMap; import com.google.android.gms.maps.OnMapReadyCallback; import com.google.android.gms.maps.model.LatLng; import com.google.android.gms.maps.model.MarkerOptions; import com.google.android.gms.tasks.OnSuccessListener; import com.google.android.gms.tasks.Task; import androidx.annotation.NonNull; import androidx.core.app.ActivityCompat; import androidx.fragment.app.FragmentActivity; public class MainActivity extends FragmentActivity implements OnMapReadyCallback { Location currentLocation; FusedLocationProviderClient fusedLocationProviderClient; private static final int REQUEST_CODE = 101 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this); fetchLocation(); } private void fetchLocation() { if (ActivityCompat.checkSelfPermission( this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission( this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, REQUEST_CODE); return; } Task<Location> task = fusedLocationProviderClient.getLastLocation(); task.addOnSuccessListener(new OnSuccessListener<Location>() { @Override public void onSuccess(Location location) { if (location != null) { currentLocation = location; Toast.makeText(getApplicationContext(), currentLocation.getLatitude() + "" + currentLocation.getLongitude(), Toast.LENGTH_SHORT).show(); SupportMapFragment supportMapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.myMap); assert supportMapFragment != null; supportMapFragment.getMapAsync(MainActivity.this); } } }); } @Override public void onMapReady(GoogleMap googleMap) { LatLng latLng = new LatLng(currentLocation.getLatitude(), currentLocation.getLongitude()); MarkerOptions markerOptions = new MarkerOptions().position(latLng).title("I am here!"); googleMap.animateCamera(CameraUpdateFactory.newLatLng(latLng)); googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(latLng, 5)); googleMap.addMarker(markerOptions); } @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { switch (requestCode) { case REQUEST_CODE: if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { fetchLocation(); } break; } } }
Step 5 – Open strings.xml and add the following code −
<resources> <string name="app_name">Sample</string> <string name="map_key" translatable="false">Enter your google API key here</string> </resources>
Step 6 – To get the google API key (map_key), kindly follow the steps below
Visit the Google Cloud Platform Console.
- Click the project drop-down and select or create the project for which you want to add an API key.
- Click the menu button
and select APIs & Services > Credentials.
- On the Credentials page, click Create credentials > API key. The API key created dialog displays your newly created API key.
- Click Close.
The new API key is listed on the Credentials page under API keys. (Remember to restrict the API key before using it in production.)
Step 7 − 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.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_COARSE_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"> <meta-data android:name="com.google.android.geo.API_KEY" android:value="@string/map_key"/> <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 –
