Android's Compatibility Definition Document Update Requires OEMs To Adhere To More Compilances

Android's Compatibility Definition Document (CDD) lays down the various conditions which the device manufacturers must meet in order to ship their devices with Android, bundled with Google's array of apps such as the Play Store.

With each and every new version update of Android, the CCD is updated with the required software and hardware norms, so that the Android experience across various devices keeps up with the minimum benchmark set by Google. For example, with the introduction of Nougat 7.1, app shortcuts, round icon support and keyboard image insertion were introduced. Each and every Original Equipment Manufacturer (OEM) needs to ensure that they include the support for the above features since they are a part of the API 25 listed in Nougat 7.1's CCD. If an OEM fails to meet the CCD guidelines, they won't be able to obtain a license from Google for shipping their devices with Google's roster of applications.

A recent update to Android 7.1's CCD has introduced a few more compilances on the software front which OEMs must adhere to. Android Police spotted that OEMs must retain Nougat's bundled notifications as well as the features of quick reply, muting the notification and accessing the application settings from the notification itself. 

XDA-Developers pointed out that this CDD update also makes sure that no applications running on Nougat 7.1 can be uninstalled without the user's permission. It is now compulsory for every device running on Android 7.1 to display a prompt-up when an app needs to be uninstalled. Following the user's response (OK or CANCEL) on the prompt-up, the desired action has to be taken. 

Google has also made the inclusion of seamless installation of updates optional. With the introduction of Nougat 7.1 in the Pixel devices, Google had introduced seamless updates, a feature which aims at installing any available OTA updates silently in the background. And then the next time the device reboots, those updates will be applied automatically. However, as per 7.1's updated CDD, it is up to OEMs whether they wish to include this feature or not.
