Google Announces Android M Developer Preview

Google on Thursday announced the Android M Developer Preview.
Like last year, Google is introducing a version of the next version of its Android operating system to developers first. This is similar to what Apple does with iOS.
Android M Developer Edition will add a few features users will be really happy to have, including:
Better control over user permissions. For apps created using the new Android M SDK, applications will now have a better way of controlling exactly what permissions an application has access to. Users will also be able to revoke permissions for applications, after they are granted.
