Not sure if unexpected (or just refreshing?), but Microsoft has released an open source Office 365 SDK for Android. What does this mean? Well, now developers can start building Android apps using the SDK to pull data from Offiice 365. Everything from Exchange contacts, emails and calendar entries, to SharePoint lists, folders, and files, will be accessible from other apps, should the developer bake Office 365 compatibility into their apps.
Right now, the SDK is available in developer preview, but interested devs can get a jump by heading over to github to learn more. Cheers.
