Microsoft Graph Android Preview Authentication Library

Use MS Graph Android Authentication library to authenticate to use Microsoft Graph API in your Android application! Use this authentication library along with msgraph-sdk-java or msgraph-sdk-java-core to make requests to Microsoft Graph APIs

Important Note about the Microsoft Graph Android Preview Authentication Library

During the preview we may make changes to the API, and other mechanisms of this library, which you will be required to take along with bug fixes or feature improvements. This may impact your application. An API change may require you to update your code. When we provide the General Availability release we will require you to update to the General Availability version within six months, as applications written using a preview version of library may no longer work.

1. Installation

1.1 Install via Gradle

Step 1 : Add this repository in project level build.gradle

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://oss.sonatype.org/content/repositories/snapshots' }
    }
}

Step 2 : Add dependency for microsoft-graph-android-auth to your app's build.gradle:

dependency {
    // Include the auth library as a dependency in app level build.gradle
    implementation 'com.microsoft.graph:microsoft-graph-android-auth:0.1.0-SNAPSHOT'
}

Step 3 : Configure your app's AndroidManifest.xml to give Internet permissions

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

Step 4 : Add BrowserTabActivity activity in AndroidManifest.xml. Make sure to put your App/Client ID at <YOUR_CLIENT_ID>.

<!--Intent filter to capture System Browser calling back to our app after Sign In-->
<activity
    android:name="com.microsoft.identity.client.BrowserTabActivity">
    <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="msal<YOUR_CLIENT_ID>"
            android:host="auth" />
        </intent-filter>
</activity>

2. Getting started

2.1 Registering your android application

Register your application by following the steps at Register your app with the Azure AD v2.0 endpoint. Once registered you will get CLIENT_ID of your application.

2.2 Create an instance of MSALAuthenticationProvider

PublicClientApplication publicClientApplication = new PublicClientApplication(getApplicationContext(), "CLIENT_ID_OF_YOUR_APPLICATION");
MSALAuthenticationProvider msalAuthenticationProvider = new MSALAuthenticationProvider(
    getActivity(),
    getApplication(),
    publicClientApplication,
    scopes);

2.3 Add auth helper in your Activity

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    msalAuthenticationProvider.handleInteractiveRequestRedirect(requestCode, resultCode, data);
}

2.4 Make requests against the Microsoft Graph REST API

Get your info

Usage in msgraph-sdk-java

IGraphServiceClient graphClient =
  GraphServiceClient
    .builder()
    .authenticationProvider(msalAuthenticationProvider)
    .buildClient();
    
User user = graphClient
  .me()
  .buildRequest()
  .get();
System.out.println(user.displayName);

Usage in msgraph-sdk-java-core

OkHttpClient graphClient = HttpClients.createDefault(msalAuthenticationProvider);
Request request = new Request.Builder().url("https://graph.microsoft.com/v1.0/me").build();
Response response = client.newCall(request).execute();
System.out.println(response.body().string());

To retrieve the user's drive

Usage in msgraph-sdk-java

IGraphServiceClient graphClient =
  GraphServiceClient
    .builder()
    .authenticationProvider(msalAuthenticationProvider)
    .buildClient();

graphClient
  .me()
  .drive()
  .buildRequest()
  .get(new ICallback<Drive>() {
     @Override
     public void success(final Drive result) {
        System.out.println("Found Drive " + result.id);
     }
     ...
     // Handle failure case
  });

Usage in msgraph-sdk-java-core

OkHttpClient graphClient = HttpClients.createDefault(msalAuthenticationProvider);
Request request = new Request.Builder().url("https://graph.microsoft.com/v1.0/me/drive").build();
Response response = client.newCall(request).execute();
System.out.println(response.body().string());
