In this blog post, we will delve into the essential steps and best practices on how to integrate Google Maps into app, unlocking the doors to a world of location-based possibilities. So, let's learn how to integrate Google Maps into an app! Enhance your app's spatial awareness and user engagement through efficient Google Maps app integration, delivering interactive mapping solutions with precision and ease.

Back-end Development for Google Maps Integration

Google Maps integrations go beyond basic navigation. Whether you're building a location-based app, a delivery service, or a real estate platform, incorporating Google Maps into your application can significantly enhance user experience. Integrating Google Maps into app isn't overly complex, but it does require a solid understanding of back-end programming, specifically in Java. Let's break down the step-by-step process.

Before delving into the programming specifics, you'll need to get a Google Maps API key. This key is unique to your application and allows Google to authenticate your app's requests.

  • Visit the Google Cloud Platform Console (
  • Create a new project or select an existing one.
  • Navigate to "APIs & Services" -> "Credentials".
  • Click "Create credentials" -> "API key".
  • After creating, copy the API key for later use.

To integrate Google Maps into app on the backend, you need the Java client library for Google Maps API Web Services. Here's how to set it up.

Add the following Maven dependency in your pom.xml:

  <version>(latest version)</version>

Now, initialize the GeoApiContext:

GeoApiContext context = new GeoApiContext.Builder()

Replace "YOUR_API_KEY" with your actual API key. This context enables you to access various Google Maps services such as Geocoding, Directions, and Places.

Let's assume you want to add geocoding to your application. Use the GeocodingApi class:

 GeocodingResult[] results =  GeocodingApi.geocode(context, "1600 Amphitheatre Parkway Mountain View, CA 94043").await();

This code will convert the address to its latitude and longitude. You can use the .lat and .lng properties on results[0].geometry.location to get these values.

How to integrate Google Maps correctly? With a clear understanding of your requirements and careful implementation, you can add useful features to your app that can greatly improve user experience. Remember to adhere to Google's usage policies and secure your API keys appropriately to prevent misuse.

Front-end Development for Google Maps Integration

Google Maps adds significant value to your web application by providing a map view of a specific area. How to integrate Google Maps into an app in terms of the front end? This integration offers several benefits regarding the front end:

  • Better user experience: The familiar and intuitive interface of Google Maps enhances website navigation and interaction for users who have already used this tool.
  • Easy location identification: Businesses with physical locations can show their addresses to potential customers, enabling them to observe the nearby area.
  • Responsiveness: Google Maps is accessible and responsive on mobile devices, catering to the growing number of mobile users and increasing the website's reach and usability.

Since many modern web projects are built using the React framework, let’s follow the instructions on integrate Google Maps into app based on React:

Step 1. Generate a Google Maps API Key

A starting point in Google Maps integration is to create a project in Google Cloud Console. The platform generates an API Key associated with that project, which serves as a form of authentication and access control when using Google Maps services within an application. To generate an API Key, follow these steps:

  1. Create a new project or select an existing one.
  2. Go to the “Credentials” section and click the “Create Credentials” button.
  3. Select the “API key” option.
  4. Copy the generated API key.

Additionally, you should enable the Maps JavaScript API service by following these steps.

  1. Navigate to the “APIs & Services” Section and click on “Enable APIs & Services”.
  2. Click the “Enable APIs and Services” button.
  3. Find the “Maps JavaScript API” service.
  4. Click the “Enable” button.

Step 2. Set up your project

Let’s start by creating a new React application using Create React App or your preferred method.

npx create-react-app project-name
cd project-name

There are several good libraries to work with Google Maps in React. In this guideline, we will use the @react-google-maps/api library. Let's install this dependency using npm or yarn.

npm i @react-google-maps/api

The @react-google-maps/api library is a React wrapper for the Google Maps JavaScript API. This library abstracts much of the boilerplate code and complexities associated with working directly with the Google Maps JavaScript API, allowing you to focus on building interactive and feature-rich map-based applications using the familiar React paradigm.

Step 3. Add Google Maps to your project

Create a file named .env in the root folder and add the following line to it, replacing YOUR_API_KEY with your actual API key.


Let’s proceed to a component where you want to display the map. In the example below, we will add this logic to the App component. The @react-google-maps/api library provides a set of components and hooks that allow you to interact with Google Maps. The core ones are:

  • LoadScript: It loads the Google Maps API script and should wrap the GoogleMap component.
  • GoogleMap: It is the main map component that accepts many props to configure the view and behavior of your map. The default ones are zoom, center, and mapContainerStyle (or mapContainerClassName).
  • Marker: It identifies a location on a map. By default, a marker uses a standard image, but it can be customized. However, Marker is a class component and may not work properly for React version 17+. There is an alternative called MarkerF - this is a functional component and it works fine for the latest versions of React.

Now let’s gather these components in the App.js file to create a map view.

import React from 'react';
import { GoogleMap, LoadScript, MarkerF } from '@react-google-maps/api';

// Coordinates of Acropolis in Athens, Greece
const center = {
  lat: 37.970833,
  lng: 23.726110,

function App() {
  return (
    <div className="App">
      <LoadScript googleMapsApiKey={process.env.REACT_APP_GOOGLE_MAPS_API_KEY}>
        <span>Acropolis, Athens</span>
          <MarkerF position={center} />

export default App;

We also need to add some styles in the index.css file to prettify our layout.

.App {
margin: 20px;

.map-container {
  margin-top: 20px;
  height: 300px;
  width: 300px;

And that’s it - we can already see the result of integrating Google Maps.

You can now customize the map, add more features, or integrate additional components like info windows, polygons, or directions depending on your specific application.

By following the steps above, you can seamlessly integrate Google Maps into your React application, enhancing its functionality and providing users with valuable location-based services. Whether you're building a business application, a travel app, or anything in between, the power of Google Maps can greatly enrich your user experience.

Mobile Development for Google Maps Integration

How to integrate Google Maps in Android app? This part will show how to set up Google Map SDK for Android and its basic usage in an Android app.

Elevate your Android app's location-based functionalities by learning how to integrate Google Maps seamlessly, enhancing user experience and providing accurate and interactive mapping services with a step-by-step guide on how to integrate Google Maps in an Android app.

The Google Maps SDK for Android is a set of tools and APIs that allows the integration of interactive maps and location-based services into Android applications. It enables users to display maps, add markers, obtain user location, calculate routes, and access various mapping and location-related features within Android apps. To use Google Maps in Android app, follow these steps:

Step 1. Obtain the API key

So how to integrate Google Maps in the Android app? To start using Google Maps API, first of all, you must obtain the API key from the Google Cloud Console (

Open the GCC and create new or select an existing project.

Then, enable the "Maps SDK for Android" API and generate an API key for the selected project.

Step 2. Set up project and dependencies

When developing the Android app, you add some external libraries, modules, or components that your app module relies on to provide additional functionality or features.

To add maps functionality into the app you need to create a new or open existing project in Android Studio.

Next, in your app-level build.gradle file, add the following dependencies under the dependencies section:

implementation '<latest_stable_verison>'
Implementation ‘’ (optional)

If you are using Jetpack Compose in your app, you will need to add ‘maps-compose’ dependency, in other cases, it’s not necessary.

Step 3. Configure API key in AndroidManifest.xml

By adding the API key to the <meta-data> element in the AndroidManifest.xml, your Android app will be able to access the Google Maps API or any other Google services that require the API key. Make sure to keep your API key secure and avoid hardcoding it if you plan to publish your app, as this could make it vulnerable to unauthorized access. Instead, consider using build flavors, build config files, or a secure backend server to manage API keys in production-ready apps.

Add the following element as a child of the <application> element:


Replace "MAPS_API_KEY" with the API key obtained in the previous step.

Step 4. Set up permissions

To use the Google Maps SDK for Android, you need to add appropriate permissions to your app's AndroidManifest.xml file. The required permissions depend on the features you want to use within the Google Maps SDK. Here are the most common permissions needed:

<uses-permission android:name="android.permission.INTERNET" /> - maps sdk requires internet access to load map tiles and other data.
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

If your app needs to display the user's current location on the map or use location-based services, you need to declare ACCESS_FINE_LOCATION. But if you only need approximate location information, you can use the ACCESS_COARSE_LOCATION permission, which requires less precision than the fine location permission.

Handling runtime permission checks is essential to ensure the user grants the necessary permissions during app runtime.

Step 5. Show GoogleMap

This step depends on which kind of UI layout you use: XML and Jetpack Compose.

Using  layout XML

If you use layout XML-based UI, you need to add MapFragment or MapView into the layout. For example, using a MapView, you need to add this code into xml layout:


Next, you need to initialize the GoogleMap object in your Activity or Fragment. In your Activity or Fragment, initialize the GoogleMap object by calling getMapAsync() on the MapView or MapFragment. For example, in onCreate() method:

 mapView.getMapAsync(object : OnMapReadyCallback {
   override fun onMapReady(googleMap: GoogleMap) {
        // Customize and interact with the GoogleMap object here

Using Jetpack Compose

If you use Jetpack Compose, then you just need to add GoogleMap composable into the composable hierarchy. This example shows adding GoogleMap, which fills available space inside the container. By just calling GoogleMap(), you can show a map in the app. Quite simple because GoogleMap is a compose container for MapView.

Inside a composable container GoogleMap can be added as an example:

modifier = Modifier
) {
		GoogleMap( params… )

Step 6. Customize the map

Inside the onMapReady() callback or when initializing the GoogleMap Composable, you can customize the map per your requirements. For example, you can add markers, set the map type, enable user gestures, etc.

Some parameters can be set in GoogleMap Composable:

  • cameraPositionState: CameraPositionState — used to control or observe the map’s camera state.
  • googleMapOptionsFactory: () -> GoogleMapOptions — the block for creating the GoogleMapOptions provided when the map is created.
  • properties: MapProperties — properties of the map like isBuildingEnabled, isIndoorEnabled, etc.
  • uiSettings: MapUiSettings— UI-specific settings on the map like compassEnabled, scrollGesturesEnabled, rotationGesturesEnabled, etc.
  • various lambdas like onMapClicked, onMapLoaded, onMyLocationButtonClick.

Using XML-based MapView, these settings can be configured inside onMapReady callback:

mapView.getMapAsync { googleMap ->
    	googleMap.uiSettings.isZoomControlsEnabled = true
googleMap.uiSettings.isMyLocationButtonEnabled = true
googleMap.uiSettings.isCompassEnabled = true
googleMap.setOnMapClickListener { latLng -> 
       // Handle map click event here
googleMap.setOnMapLoadedCallback {
       	      // Handle map loaded event here
    	googleMap.setOnMyLocationButtonClickListener {
      // Handle My Location button click event here

The Google Maps SDK for Android allows to integrate powerful mapping and location-based services into Android applications. Adding the SDK to the projects allows you to display interactive maps, add markers, draw routes, and access geospatial data.

The SDK provides a range of features, such as customizing map styles, enabling user location tracking, and implementing map gestures.

Now, use Google Maps in Android app to leverage powerful mapping and location-based services, enhancing the user experience with dynamic and interactive map functionalities.

The steps that we provided above will help to get started with maps integration and use Google Maps in Android app. Still, for more information about your business requirements, you will also need to check the official documentation from Google.
