With the cloud-based service, developers can finally allow their apps to send updates and other information to individual Kindle devices. While this sort of centralized notification system is already built into Android (and iOS), it’s so far been noticeably absent from Amazon’s custom fork of Google’s operating system.
One of the most significant components of the service is that it doesn’t have to ping servers constantly in order to get updates. Not only is this much better for a device’s battery life, but it cuts down on data transmission as well. These are both pivotal features in mobile devices, which is why the service will be an indispensable component of any future Kindle smartphone. (And it’s good news for the current Kindle tablets, too.)
Developers should be happy with Amazon Device Messaging as well, because it can help make their Kindle apps as robust as those on other platforms.
