Google released a new version of its Compatibility Definition Document for Android earlier this week, and while most of the changes are very, very minor, one did stand out to me in the section on notifications. Specifically, Google has singled out manufacturers who in any way obstruct or remove Android's native notification actions, replies, settings access, and the bundling of notifications. The latest document forbids such practices, stating that OEMs must comply with Google's implementations of the features in AOSP. Here is the relevant section:
Handheld device implementations MUST support the behaviors of updating, removing, replying to, and bundling notifications as described in this section.
