Migrating from the Azure Maps Android SDK to the Web SDK in a WebView involves transitioning your existing map view from a native implementation to a web-based map using the Azure Maps Web SDK. This guide shows you how to migrate your code and features from the Android SDK to the Web SDK.

Note

Azure Maps Android SDK retirement

The Azure Maps Native SDK for Android is now deprecated and will be retired on 3/31/25. To avoid service disruptions, migrate to the Azure Maps Web SDK by 3/31/25.

Prerequisites

To use the Map Control in a web page, you must have one of the following prerequisites:

An Azure Maps account.
A subscription key or Microsoft Entra credentials. For more information, see authentication options.

Create a WebView

Add a WebView if your Android application doesn't have one. Do so by adding the WebView element to your layout XML or programmatically in your Java code. Be sure it's configured to occupy the desired area of your layout.

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <WebView
        android:id="@+id/webView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</androidx.coordinatorlayout.widget.CoordinatorLayout>

Enable internet access by adding permissions in AndroidManifest.xml.

<uses-permission android:name="android.permission.INTERNET" />

In your activity or fragment, initialize the WebView and enable JavaScript by updating the settings. Load the HTML file that contains the Web SDK code. You can either load it from the assets folder or from a remote URL.

import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import android.webkit.WebSettings;
import android.webkit.WebView;

public class MainActivity extends AppCompatActivity {

    private WebView webView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);
        webView = findViewById(R.id.webView);

        // Enable JavaScript
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);

        // Load local HTML file from /src/main/assets/map.html
        webView.loadUrl("file:///android_asset/map.html");
    }
}

Set up a map with Azure Maps Web SDK

In your HTML file, initialize a map with your subscription key. Replace <YOUR_SUBSCRIPTION_KEY> with your actual key.

<!DOCTYPE html>
<html>
   <head>
       <title>Azure Maps</title>
       <meta charset="utf-8" />
       <meta name="viewport" content="width=device-width, initial-scale=1" />
       <!-- Add references to the Azure Maps Map control JavaScript and CSS files. -->
       <link rel="stylesheet" href="https://atlas.microsoft.com/sdk/javascript/mapcontrol/3/atlas.min.css" type="text/css"/>
       <script src="https://atlas.microsoft.com/sdk/javascript/mapcontrol/3/atlas.min.js"></script>
       <style>
           html,
           body,
           #map {
               margin: 0;
               height: 100%;
               width: 100%;
           }
           body {
               display: flex;
               flex-direction: column;
           }
           main {
               flex: 1 1 auto;
           }
       </style>
       <script type="text/javascript">
           // Create an instance of the map control.
           function InitMap() {
               var map = new atlas.Map("map", {
                   center: [-122.33, 47.6],
                   zoom: 12,
                   authOptions: {
                       authType: "subscriptionKey",
                       subscriptionKey: "<YOUR_SUBSCRIPTION_KEY>"
                   }
               });

               // Wait until the map resources are ready.
               map.events.add("ready", function () {
                   // Resize the map to fill the container.
                   map.resize();
               });
           }
       </script>
   </head>
   <body onload="InitMap()">
       <main>
           <div id="map"></div>
       </main>
   </body>
</html>

Save and run the app. A map will appear within a WebView. Add any required features or functionality from the Web SDK. For more information, see Azure Maps Documentation and Azure Maps Samples.

Communication between native code and WebView (optional)

To enable communication between your Android application and the WebView, you can use the WebView's addJavascriptInterface method to expose a Java object to the JavaScript running in the WebView. It allows you to call Java methods from your JavaScript code. For more information, see WebView in the Android documentation.

Clean Up Native Map Implementation

Remove code related to the native Azure Maps Android SDK, including dependencies and initialization code related to com.azure.android:azure-maps-control.

Testing

Test your application thoroughly to ensure the migration was successful. Check for issues related to map functionality, user interactions, and performance.
