Tutorial: Create an Android app that uses the Microsoft identity platform for authentication - Microsoft identity platform

आलेख
02/24/2024

In this tutorial, you build an Android app that integrates with the Microsoft Entra ID to sign in users and get an access token to call the Microsoft Graph API.

When you've completed this tutorial, your application accepts sign-ins of personal Microsoft accounts (including outlook.com, live.com, and others) and work or school accounts from any company or organization that uses Microsoft Entra ID.

In this tutorial:

Create an Android app project in Android Studio
Register the app in the Microsoft Entra admin center
Add code to support user sign-in and sign-out
Add code to call the Microsoft Graph API
Test the app

Prerequisites

How this tutorial works

Screenshot of how the sample app generated by this tutorial works.

The app in this tutorial signs in users and get data on their behalf. This data is accessed through a protected API (Microsoft Graph API) that requires authorization and is protected by the Microsoft identity platform.

This sample uses the Microsoft Authentication Library (MSAL) for Android to implement Authentication: com.microsoft.identity.client.

Create a project

Follow these steps to create a new project if you don't already have an Android application.

Open Android Studio, and select Start a new Android Studio project.
Select Basic Activity and select Next.
Enter a name for the application, such as MSALAndroidapp.
Record the package name to be used in later steps.
Change the language from Kotlin to Java.
Set the Minimum SDK API level to API 16 or higher, and select Finish.

Register your application with Microsoft Entra ID

Tip

Steps in this article might vary slightly based on the portal you start from.

Sign in to the Microsoft Entra admin center as at least an Application Developer.
If you have access to multiple tenants, use the Settings icon in the top menu to switch to the tenant in which you want to register the application from the Directories + subscriptions menu.
Browse to Identity > Applications > App registrations.
Select New registration.
Enter a Name for your application. Users of your app might see this name, and you can change it later.
For Supported account types, select Accounts in any organizational directory (Any Microsoft Entra directory - Multitenant) and personal Microsoft accounts (e.g. Skype, Xbox). For information on different account types, select the Help me choose option.
Select Register.
Under Manage, select Authentication > Add a platform > Android.
Enter your project's Package Name. If you downloaded the sample code, this value is com.azuresamples.msalandroidapp.
In the Signature hash section of the Configure your Android app pane, select Generating a development Signature Hash. and copy the KeyTool command to your command line.
- KeyTool.exe is installed as part of the Java Development Kit (JDK). You must also install the OpenSSL tool to execute the KeyTool command. For more information, see Android documentation on generating a key for more information.
Enter the Signature hash generated by KeyTool.
Select Configure and save the MSAL Configuration that appears in the Android configuration pane so you can enter it when you configure your app later.
Select Done.

Configure your application

In Android Studio's project pane, navigate to app\src\main\res.
Right-click res and choose New > Directory. Enter raw as the new directory name and select OK.

In app > src > main > res > raw, create a new JSON file called auth_config_single_account.json and paste the MSAL Configuration that you saved earlier.

Below the redirect URI, paste:

  "account_mode" : "SINGLE",

Your config file should resemble this example:

{
  "client_id": "00001111-aaaa-bbbb-3333-cccc4444",
  "authorization_user_agent": "WEBVIEW",
  "redirect_uri": "msauth://com.azuresamples.msalandroidapp/00001111%cccc4444%3D",
  "broker_redirect_uri_registered": true,
  "account_mode": "SINGLE",
  "authorities": [
    {
      "type": "AAD",
      "audience": {
        "type": "AzureADandPersonalMicrosoftAccount",
        "tenant_id": "common"
      }
    }
  ]
}

As this tutorial only demonstrates how to configure an app in Single Account mode, see single vs. multiple account mode and configuring your app for more information

We recommend using 'WEBVIEW'. In case you want to configure "authorization_user_agent" as 'BROWSER' in your app, you need make the following updates. a) Update auth_config_single_account.json with "authorization_user_agent": "Browser". b) Update AndroidManifest.xml. In the app go to app > src > main > AndroidManifest.xml, add the BrowserTabActivity activity as a child of the <application> element. This entry allows Microsoft Entra ID to call back to your application after it completes the authentication:
```

<activity
    android:name="com.microsoft.identity.client.BrowserTabActivity"
    android:exported="true">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="msauth"
            android:host="Enter_the_Package_Name"
            android:path="/Enter_the_Signature_Hash" />
    </intent-filter>
</activity>
```
- Use the Package name to replace android:host=. value. It should look like com.azuresamples.msalandroidapp.
- Use the Signature Hash to replace android:path= value. Ensure that there's a leading / at the beginning of your Signature Hash. It should look like /aB1cD2eF3gH4+iJ5kL6-mN7oP8q=.
You can find these values in the Authentication blade of your app registration as well.

Add MSAL and relevant libraries to your project

In the Android Studio project window, navigate to app > build.gradle and add the following libraries in the dependencies section:
```
 implementation 'com.microsoft.identity.client:msal:5.0.0'
 implementation 'com.android.volley:volley:1.2.1'
```
In the Android Studio project window, open settings.gradle and declare the following maven repository in dependencyResolutionManagement > repositories section:
```
 maven {
      url 'https://pkgs.dev.azure.com/MicrosoftDeviceSDK/DuoSDK-Public/_packaging/Duo-SDK-Feed/maven/v1'
 }
```
Select Sync Now in the notification bar.

Create and update required fragment

In app > src > main> java > com.example(your app name). Create the following Android fragments:
- MSGraphRequestWrapper
- OnFragmentInteractionListener
- SingleAccountModeFragment

Open MSGraphRequestWrapper.java and replace the code with following code snippet to call the Microsoft Graph API using the token provided by MSAL:

 package com.azuresamples.msalandroidapp;

     // See: https://docs.microsoft.com/en-us/graph/deployments#microsoft-graph-and-graph-explorer-service-root-endpoints
     public static final String MS_GRAPH_ROOT_ENDPOINT = "https://graph.microsoft.com/";

     /**

     public static void callGraphAPIUsingVolley(@NonNull final Context context,
                                                @NonNull final String graphResourceUrl,
                                                @NonNull final String accessToken,
                                                @NonNull final Response.Listener<JSONObject> responseListener,
                                                @NonNull final Response.ErrorListener errorListener) {
         Log.d(TAG, "Starting volley request to graph");

         /* Make sure we have a token to send to graph */
         if (accessToken == null || accessToken.length() == 0) {
             return;
         }

         RequestQueue queue = Volley.newRequestQueue(context);
         JSONObject parameters = new JSONObject();

         try {
             parameters.put("key", "value");
         } catch (Exception e) {
             Log.d(TAG, "Failed to put parameters: " + e.toString());
         }

         JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, graphResourceUrl,
                 parameters, responseListener, errorListener) {
             @Override
             public Map<String, String> getHeaders() {
                 Map<String, String> headers = new HashMap<>();
                 headers.put("Authorization", "Bearer " + accessToken);
                 return headers;
             }
         };

         Log.d(TAG, "Adding HTTP GET to Queue, Request: " + request.toString());

         request.setRetryPolicy(new DefaultRetryPolicy(
                 3000,
                 DefaultRetryPolicy.DEFAULT_MAX_RETRIES,
                 DefaultRetryPolicy.DEFAULT_BACKOFF_MULT));
         queue.add(request);
     }
 }

Open OnFragmentInteractionListener.java and replace the code with following code snippet to allow communication between different fragments:

 package com.azuresamples.msalandroidapp;

 /**
  * This interface must be implemented by activities that contain this
  * fragment to allow an interaction in this fragment to be communicated
  * to the activity and potentially other fragments contained in that

  * "http://developer.android.com/training/basics/fragments/communicating.html"
  * >Communicating with Other Fragments</a> for more information.
  */
 public interface OnFragmentInteractionListener {
 }

Open SingleAccountModeFragment.java and replace the code with following code snippet to initialize a single-account application, loads a user account, and gets a token to call the Microsoft Graph API:

Layout

A layout is a file that defines the visual structure and appearance of a user interface, specifying the arrangement of UI components. It's written in XML. The following XML samples are provided if you would like to model your UI off this tutorial:

In app > src > main> res > layout > activity_main.xml. Replace the content of activity_main.xml with the following code snippet to display buttons and text boxes:

 <?xml version="1.0" encoding="utf-8"?>
 <androidx.drawerlayout.widget.DrawerLayout 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:id="@+id/drawer_layout"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:fitsSystemWindows="true"
     tools:openDrawer="start">

     <include
         layout="@layout/app_bar_main"
         android:layout_width="match_parent"
         android:layout_height="match_parent" />

     <com.google.android.material.navigation.NavigationView
         android:id="@+id/nav_view"
         android:layout_width="wrap_content"
         android:layout_height="match_parent"
         android:layout_gravity="start"
         android:fitsSystemWindows="true"
         app:headerLayout="@layout/nav_header_main"
         app:menu="@menu/activity_main_drawer" />

 </androidx.drawerlayout.widget.DrawerLayout>

In app > src > main> res > layout > app_bar_main.xml. If you don't have app_bar_main.xml in your folder, create and add the following code snippet:

<?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"

            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </com.google.android.material.appbar.AppBarLayout>

    <include layout="@layout/content_main" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>

In app > src > main> res > layout > content_main.xml. If you don't have content_main.xml in your folder, create and add the following code snippet:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/content_main"

    tools:context=".MainActivity"
    tools:showIn="@layout/app_bar_main">

</androidx.constraintlayout.widget.ConstraintLayout>

In app > src > main> res > layout > fragment_m_s_graph_request_wrapper.xml. If you don't have fragment_m_s_graph_request_wrapper.xml in your folder, create and add the following code snippet:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"

        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@string/hello_blank_fragment" />

</FrameLayout>

In app > src > main> res > layout > fragment_on_interaction_listener.xml. If you don't have fragment_on_interaction_listener.xml in your folder, create and add the following code snippet:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

Declaring your UI in XML allows you to separate the presentation of your app from the code that controls its behavior. To learn more about Android layout, see Layouts

Test your app

Run locally

Build and deploy the app to a test device or emulator. You should be able to sign in and get tokens for Microsoft Entra ID or personal Microsoft accounts.

After you sign in, the app will display the data returned from the Microsoft Graph /me endpoint.

The first time any user signs into your app, they'll be prompted by Microsoft identity to consent to the permissions requested. Some Microsoft Entra tenants have disabled user consent, which requires admins to consent on behalf of all users. To support this scenario, you'll either need to create your own tenant or receive admin consent.

Clean up resources

When no longer needed, delete the app object that you created in the Register your application step.
