Microsoft Graph SDK for Java

Get started with the Microsoft Graph SDK for Java by integrating the Microsoft Graph API into your Java application!

1. Installation

1.1 Install via Gradle

Add the repository and a compile dependency for microsoft-graph to your project's build.gradle:

repository {
    jcenter()
}

dependency {
    // Include the sdk as a dependency
    compile('com.microsoft.graph:microsoft-graph:1.5.+')
}

1.2 Install via Maven

Add the dependency in dependencies in pom.xml

<dependency>
	<groupId>com.microsoft.graph</groupId>
	<artifactId>microsoft-graph</artifactId>
	<version>1.5.0</version>
</dependency>

1.3 Enable ProGuard (Android)

The nature of the Graph API is such that the SDK needs quite a large set of classes to describe its functionality. You need to ensure that ProGuard is enabled on your project. Otherwise, you will incur long build times for functionality that is not necessarily relevant to your particular application. If you are still hitting the 64K method limit, you can also enable multidexing.

2. Getting started

2.1 Register your application

2.2 Create an IAuthenticationProvider object

An instance of the GraphServiceClient class handles building requests, sending them to the Microsoft Graph API, and processing the responses. To create a new instance of this class, you need to provide an instance of IAuthenticationProvider, which can authenticate requests to Microsoft Graph.

For an example of authentication in a client application, see the MSGraph SDK Android MSA Auth for Android Adapter.

2.3 Get a GraphServiceClient object

After you have set the correct application ID and URL, you must get a GraphServiceClient object to make requests against the service. The SDK stores the account information for you, but when a user signs in for the first time, it invokes the UI to get the user's account information.

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

3. Make requests against the service

After you have a GraphServiceClient that is authenticated, you can begin making calls against the service. The requests against the service look like our REST API.

3.1 Get the user's drive

To retrieve the user's drive:

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
  });
