Amazon Device Messaging, a free service that allows you to send cloud-based push notifications to Kindle Fire customers, is now out of Beta and is in general availability.

You can use ADM to send encrypted real-time notification to update users on breaking news or let them know that a new game task is available for them to complete. You can also use ADM for instant messaging functionality or social networking notifications within your app.

Messaging Overview

• Deployment. We have documentation, sample code, tools, and FAQs to help you integrate ADM. Adding ADM to your app is easy. You obtain your ADM credentials and key (remember, this is an encrypted message), include the ADM library as an external JAR file, update your manifest, store your key as an asset, and implement your broadcast receiver. (we have sample code that shows this). To send a message, your server needs the app registration ID and a security token. You can find more implementation details here.
• Simple. ADM delivers message data to your app on the device, and your app can decide what to do on receipt of that data like download content or display a notice. Your message should be no greater than 6KB in size and sent in the form of JSONObject key:value pairs.
• Delivery. Messages expiration is one week by default, but can be configured to persist for one month if required. ADM will wake up the device to deliver messages, so messages can be sent and received during off-peak hours when the device is likely to be asleep. We use Amazon Web Services as a backend for this service, so we can scale up quickly and reliably.
• Compatibility. ADM is supported on Kindle Fire HD 8.9" 4G, Kindle Fire HD 8.9", Kindle Fire HD 7", and Kindle Fire (2nd Generation) devices.
• Free. Enough said.

Feedback from the Beta

During the ADM beta, we had big and small companies try the service, and we got international developer feedback as well. Here is some of the feedback we received:

From Wooga, a social game developer based in Berlin:

“The decision to integrate Amazon Device Messaging into Diamond Dash was a cinch – it is a clear win”, said Soenke Bullerdiek, Senior Manager Strategic Platform Partnerships, from Wooga, “Even better, it was easy to enable and only took a few days of work to start sending push notifications to our users.”

From Gameloft, a world-wide game developer based in the U.S.:

“We decided to use Amazon Device Messaging as a new way to engage our Oregon Trail American Settlers customers on Kindle Fire.  The documentation and sample code was easy to understand for our studios.” Baudouin Corman, VP Americas Gameloft.
