Microsoft has released a public preview of its Graph Java/Android SDK, and the company is looking for feedback on the release.

Redmond defines the Microsoft Graph as "the gateway to data and intelligence in Microsoft 365." It's designed to provide a unified programmability model that developers can use to access the data in Microsoft 365, Windows 10, and Enterprise Mobility + Security. The Graph API provides a single endpoint (  https://graph.microsoft.com) for accessing "rich, people-centric data and insights exposed as resources of Microsoft 365 services," the company says.
