According to The Verge who was on hand for the announcement, Xbox Live for Android will offer developers the ability to build party systems, messaging, Xbox achievements, Microsoft sign-in, as well as cloud saves into mobile games.
"Over the past 16 years, Xbox Live has become one of the most vibrant and engaged gaming communities in the world". The goal is that by using Xbox Live services, the mobile developer will be able to easily tap into the already established Xbox community to drive more adoption of the new application. The new SDK makes Xbox Live support available for all.
By opening up Xbox Live to other platforms, Microsoft is accelerating the slow pivot from the online service being tied explicitly to a console and instead positioning it as a fabric for online gaming.
Microsoft is bringing Xbox Live to mobile games on iOS and Android
"We believe so strongly in community, and Xbox Live really being at the heart of our gaming community", explains Kareem Choudhry, Microsoft's gaming cloud chief in a media briefing this week. Today we got the official announcement. but Nintendo Switch support is mysteriously missing.
Microsoft is making this move as a part of its overall Game Stack initiative with which it is bringing all its various game development tools into a single platform.
As of now, I am not too optimistic of game developers rushing to integrate Xbox Live in their iOS games.
