Android provides facility to integrate Google map in our application. Google map displays your current location, navigate location direction, latitude ,longitude, search location etc. We can also customize Google map according to our requirement.
- Normal.
- Hybrid.
- Satellite.
- Terrain.
- None.
- googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
- googleMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
- googleMap.setMapType(GoogleMap.MAP_TYPE_SATELLITE);
- googleMap.setMapType(GoogleMap.MAP_TYPE_TERRAIN);
- Copy the URL from google_map_api.xml file to generate Google map key.
- Paste the copied URL at the browser. It will open the following page.
- Click on Create API key to generate API key.
- After clicking on Create API key, it will generate our API key displaying the following screen.
- Copy this generated API key in our google_map_api.xml file
- Now you have to add the map fragment into xml layout file. Its syntax is given below −
<?xml version="1.0" encoding="utf-8"?> <fragment xmlns:android="http://schemas.android.com/apk/res/android" xmlns:map="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/map" android:name="com.google.android.gms.maps.SupportMapFragment" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MapsActivity" />
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.mantra.thecodehubsgooglemaps"> <!-- The ACCESS_COARSE/FINE_LOCATION permissions are not required to use Google Maps Android API v2, but you must specify either coarse or fine location permissions for the "MyLocation" functionality. --> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="com.google.android.providers.gsf.permission.

- Required Permission:-
Add the following user-permission in AndroidManifest.xml file.<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> <uses-permission android:name="android.permission.INTERNET" />
- MapsActivity.java
package com.mantra.thecodehubsgooglemaps; import androidx.fragment.app.FragmentActivity; import android.os.Bundle; import com.google.android.gms.maps.CameraUpdateFactory; import com.google.android.gms.maps.GoogleMap; import com.google.android.gms.maps.OnMapReadyCallback; import com.google.android.gms.maps.SupportMapFragment; import com.google.android.gms.maps.model.LatLng; import com.google.android.gms.maps.model.MarkerOptions; public class MapsActivity extends FragmentActivity implements OnMapReadyCallback { private GoogleMap mMap; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_maps); // Obtain the SupportMapFragment and get notified when the map is ready to be used. SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() .findFragmentById(R.id.map); mapFragment.getMapAsync(this); } /** * Manipulates the map once available. * This callback is triggered when the map is ready to be used. * This is where we can add markers or lines, add listeners or move the camera. In this case, * we just add a marker near Sydney, Australia. * If Google Play services is not installed on the device, the user will be prompted to install * it inside the SupportMapFragment. This method will only be triggered once the user has * installed Google Play services and returned to the app. */ @Override public void onMapReady(GoogleMap googleMap) { mMap = googleMap; // Add a marker in Sydney and move the camera LatLng sydney = new LatLng(21.200896, 72.8236032); mMap.addMarker(new MarkerOptions().position(sydney).title("Vision Infotech")); mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney)); } }
Now you can run your project.
