Starting today, developers have the opportunity to participate in a Developer Preview of Fire OS 5, the next generation Android-based operating system that powers Fire tablets, Amazon Fire TV and Fire TV Stick. And because Fire OS 5 is based on Android Lollipop, we can make this update while preserving even more compatibility with existing Android apps than ever before. This means that even more of your apps should work on Fire devices with no additional engineering effort. There are several ways you can participate in the Fire OS 5 Developer Preview.
To ensure your app is available to millions of customers on the next generation of Amazon devices, you can now participate in the Fire OS 5 Developer Preview. As an Amazon Developer, we’re offering you early access to Fire OS 5. You can now see your app running on a Fire HD 6 or Fire HD 7 tablet, and identify any app compatibility issues well in advance of our new Fire OS launch later this year.
To participate in the Fire OS 5 Developer Preview, click here.
Amazon Testing Service is a free tool that allows you to test your app for compatibility on Fire and Android devices. We’ve updated Amazon Testing Service to provide feedback on your apps compatibility with Fire OS 5 and Android Lollipop. To test your app, simply drag and drop your Android APK into the App Testing Service on the Amazon Developer Portal homepage page. In about 90 seconds, you will get compatibility results for Fire OS 5 and Android Lollipop.
Now is the time to get started. Check out the resources below to learn more about Fire OS5 and the Amazon Appstore

Today we are pleased to release new Android and iOS SDKs for mobile developers interested in supporting Amazon Cloud Drive. These new additions are a part of the existing Amazon Mobile App SDK and can be downloaded directly from the Developer Portal. The updates will allow you to provide Unlimited Storage benefits for your customers using your apps more quickly and efficiently.
You can now quickly write new apps or make your existing apps interact with Amazon Cloud Drive using both the Android and iOS SDKs. With these updates you no longer need to understand and implement a separate instance of Login with Amazon. We’ve even taken care of the best practices of implementing a back-off strategy. Best of all, you can communicate with the Amazon Cloud Drive API without ever needing to worry about networking code.
Additional benefits include the ability to work exclusively with native Java and Objective-C object types, removing the need to ever parse JSON, as well as eliminating the need to refer back to the REST API documentation online. You also no longer need to explicitly use the Amazon Cloud Drive API to get Account endpoints, removing an entire step from your development workflow.
With the launch of the Amazon Cloud Drive mobile developer SDKs, we are also excited to announce new third-party apps supporting Cloud Drive through the Android and iOS SDKs.

Cross Platform Engines have become critical tools for developers to build applications once and deploy their apps across the Google, Apple, and Amazon ecosystems to reach the greatest number of consumers. Amazon has developed a number of plugins for cross platform tools to allow developers to utilize Amazon Services without the need to write boilerplate code to bridge cross platform code with native language Amazon APIs. Amazon has released new plugins for Apache Cordova, Unity, Adobe Air, and Xamarin to allow developers to monetize their cross platform apps using Amazon In-App Purchasing. The In-App Purchasing (IAP) API makes it easy to offer digital content and subscriptions for purchase within your app. The newly released plugins enable cross platform developers to quickly get up and running, and give millions of Amazon customers the ability to purchase engaging digital content using Amazon 1-Click settings. To learn more about IAP and pick up the latest plugin, check out the Amazon In-App Purchasing site.
Before you can use a plugin in an app, you need to include the plugin in the cross platform tool for use. Each tool has its own specific set of steps, and we have created a page to guide you through this process for Unity, Xamarin, Cordova, and Adobe Air.
If you have never monetized an app or are new to Amazon IAP, it would be good to familiarize yourself with what In-App purchasing is here. There were plugins built for Unity and Adobe Air for IAP v1. If you are migrating your current app to the new IAP v2 plugin, now would be a good time to review what is new and the IAP v1 to IAP v2 migration guide. And finally, if your current app uses Google Play In-App Billing (IAB), review the Amazon migration guide for Google Play developers for guidance on migrating your app to Amazon IAP.
During development, it’s a good idea to verify purchasing works in your app and you are able to handle successful purchases and error scenarios. To test your app, you should download and install the Amazon App Tester. The Amazon App Tester is a mobile app that is available in the Amazon Appstore. You will need to download the Amazon Appstore to purchase and download the tester app to your test device. Review the IAP Testing guide to unit test IAP purchases in your app.
The IAP cross platform plugins are part of a single Amazon In-App Purchasing SDK (which you can download here) that also provides access to other Amazon mobile services and additional free plugins such as the plugin for GameCircle.
To use the IAP plugins in your cross platform tool, first download the SDK and extract the zip file to the appropriate location on your development machine. Here’s what the Unity plugin part of the SDK folder looks like on my machine. The plugins can be found off the root directory inside the zip file by their respective cross-platform tool name, AIR, Unity, Cordova, or Xamarin.
Each plugin makes similar sets of calls to the native IAP Java SDK, but making calls through the plugin differs based on the cross platform tool and language semantics. There are code samples for each plugin type and I would suggest playing with the code samples in a test app. Check out the code samples in your cross platform user’s guide below.
Plugins make it easier than ever to integrate Amazon IAP, and other Amazon services into your mobile app. You can now monetize your cross platform app without the need to write your own plugin or boilerplate code to integrate the native Java SDK and focus instead on building great apps and reach millions of Amazon Appstore customers. Once you have used the plugin to integrate the Amazon IAP API, you will get paid for any In-App purchases your customers make in your app.
Here are some additional useful links to Amazon’s Cross Platform Engine support and Amazon In-App purchasing:

We are excited to announce that developers can now monetize their Amazon apps with TrialPay, a leader in cross-platform monetization and reward-based advertising. By integrating the TrialPay Evergreen SDK or native ads API, developers can dynamically surface any type of ad format including native ads, offer walls, or videos. This enables Amazon developers to monetize users who don’t typically buy IAP items by offering them ads they can interact with in exchange for in-app currency.
For example, users can watch a movie trailer or buy flowers for Mother’s Day to earn in-app currency. Giving users a way to enjoy IAP items for free makes TrialPay an attractive tool for increasing the number of paying users. Industry leaders such as Glu, Zynga, and Kik use TrialPay to enhance their ad offerings.
“TrialPay is a great partner with deep experience in mobile advertising. They are strong technologists who continue to create unique opportunities for advertisers to connect with users through Kik Points.”
Jairaj Sethi, Head of Platform, Kik
As of late, TrialPay is also helping developers tap into the online-to-offline opportunity by rewarding users for everyday purchases at retailers such as Peet’s Coffee and Sephora.
Image caption: TrialPay Peet’s offline offer - buy coffee and earn in-app currency
Their event-based Evergreen SDK lets developers show offers that are contextually relevant to events in their apps. Developers have easy dashboard controls to toggle dynamically between ad formats.
In addition, TrialPay’s Native Offers API provides access to a wide variety of ad types, supporting app installs, video, and seasonal promotions. Developers have complete control over the UI to match the look and feel of their app and integrate more deeply with the app experience.
Developers have a choice on the integration method. TrialPay offers both a lightweight SDK and a Native Offers API option. Visit the TrialPay Mobile Development Center to get implementation details. You can also email email@example.com for more information. Mention this Amazon blog post in the subject line to be paired with a dedicated account manager today.
In April, Amazon introduced Amazon Fire TV, and it quickly became the most wished for item by Prime members in 2014. Amazon Fire TV, made it easier for customers to watch Netflix, Prime Instant Video, Hulu Plus, WatchESPN, and more on their big-screen TV, and brought photos, music, and games to the living room. In October, we brought the same experience customers love about Amazon Fire TV—ease of use, great performance, and vast selection—to a smaller and even more affordable device - Fire TV Stick, which is the fastest-selling Amazon device ever.
This week, we announced that Amazon Fire TV has the fastest growing selection of any streaming media device. In just the last 3 months, Amazon has added over 600 channels, apps and games to the Amazon Fire TV platform—more than Roku and Apple TV in the same timeframe. Popular new titles include Popcornflix, Funny Or Die, GameFly, Candy Crush Saga, and Fox News.
For developers, one of the most exciting prospects of publishing your game on Amazon Fire TV is that you can run Android games directly on the TV. If you are already building games for Android, you can use the same codebase you currently have, and make that game playable on Amazon Fire TV.
While you may be familiar with targeting Android tablets and phones, there are a few things you need to consider for your app to run correctly on Amazon Fire TV. Below is a quick round-up of some of the great content we’ve created since the device launched to help make the transition easy.
Gone are the days where you can make a game and publish it to a single platform and expect to be successful. Like any business that sells consumer products, you need to go where the people are. That means the games you make should run on a multitude of different platforms and accept any number of different input types. With that in mind I have outlined what I call “responsive game design,” which is modeled loosely after some of the core concepts of responsive web design. It’s also a framework that will help you think about enabling your games to scale across multiple platforms. Click here to learn more.
If you’re porting an existing Android app to Fire TV, you have to add support for user input from the Amazon Fire TV remote and maybe the Amazon Fire game controller. Luckily, basic controller support is already built into Android. You can leverage the Android input device APIs and the game controller API from the Amazon Fire TV SDK to get your game ready to publish in no time. Here are the top ten things you should do in order to get your game ready for Amazon Fire TV customers.
While you may be familiar with targeting Android tablets and phones, there are a few things you need to consider for your app to run correctly on Amazon Fire TV. This includes understanding the layout, dimensions and orientation of Amazon Fire TV views, changes to the user experience when interacting with a TV (10’ away on average), UI and navigation patterns, as well as some other TV-specific gotchas such as overscan and color reproduction. Here are some practical tips to help you get your Android apps looking good on Fire TV.
Fire TV Stick is one of the most affordable devices on the market for creating apps and casual games intended for the big screen. The best part is if you are already building for Android, Fire TV stick is another great platform to help grow your audience. In this post we cover how to get started, optimizing for Fire TV Stick as well as the hardware/software differences between the Fire TV Stick and Fire TV to help make your apps and games run great on both devices.
Xamarin is a cross platform development environment that leverages the power of the C# programming language and takes full advantage of native hardware acceleration. Xamarin includes a suite of tools that allow you to test, build, and analyze your apps across all of the major mobile platforms. Utilizing Xamarin you can now publish your own apps and games to all Amazon Fire devices. This includes Amazon Fire tablets, Amazon Fire phone, Amazon Fire TV and the recently announced Amazon Fire TV Stick. Click here to learn how to get your app or game running on Fire TV using Xamarin.
Fire TV and Fire TV Stick both support HTML5 web apps. The Web App Starter Kit for Fire TV is a new open source project intended to help developers get up to speed quickly creating a simple media-oriented app for this exciting new web platform. Features of the project include an example user interface designed for the 10-foot user experience, support for the Fire TV remote control, and sample components to create and customize a media app. You can learn more about the Web App Starter Kit for Fire TV here.
Today, we announced a new Amazon Fire TV web app kit for Brightcove, a company that offers cloud services for delivering and monetizing video across connected devices. Brightcove has over 5,500 customers in over 70 countries. Read the full press release here.
The Brightcove-specific web app kit for Amazon Fire TV is a new HTML5 template available to Brightcove Video Cloud customers that optimizes the delivery of Brightcove Video Cloud customers' content directly to Amazon Fire TV. The kit enables content owners to leverage their existing Brightcove-based workflows for Amazon Fire TV. For Brightcove customers, the template provides a way to seamlessly pull in content that’s hosted and organized in Video Cloud and use the Brightcove Player. Because of the integration with the Brightcove Player, customers can run ads against their content on Amazon Fire TV using the Google IMA3 advertising plugin and also capture analytics about video consumption on Amazon Fire TV in Video Cloud. Learn more about Brightcove and Amazon Fire TV.
RLJ Entertainment is an example of a Brightcove customer that is eager to leverage the new template across its multiple properties. Titus Bicknell, Chief Digital Officer at RLJ Entertainment said:
"We're excited about the reach and high-quality experience we'll be able to provide our audience on Amazon Fire TV. As we look to launch our Acorn TV (British TV), UMC (Urban Movie Channel), and AcaciaTV (Fitness) apps, the new template will greatly simplify the release of our current and future niche channels.”
It’s easy for Brightcove customers to get started using the sample project on GitHub. The Brightcove example is in the src/projects/brightcove directory. You can quickly get this project up and running on Fire TV by creating a zip package with the sample Brightcove app that can be found in out/brightcove/ directory. This is just a standard zip, but the index.html must be at the top level of the zip directory - so that there if you unzip the package there is no folder.
Once you’re up and running, you can test your app on Fire TV or in a browser, customize your project, and add additional features. Read the Brightcove documentation on GitHub here.

Today, Amazon is happy to announce that Appstore developers can now integrate the AppLovin SDK and start monetizing their Amazon apps with ads from Applovin. According to Applovin, they process over 30 billion advertisement requests a day and use real-time feedback to make effective marketing decisions across 1 billion mobile consumers worldwide - delivering results for publishers like Disney, Uber, Groupon, CBS, Hotels.com, Yelp, Zynga, and King.com and others.
Because the AppLovin platform optimizes advertiser campaigns for ROI, advertisers see a higher return on their ad spend and are willing to pay for the quality placements they receive. By providing top quality ad placements, with the hundreds of top brands they work with, they can then serve ads at a massive scale, thereby maximizing developers’ earnings. Moreover, with AppLovin, developers get paid quickly -- just 15 days after month-end.
“AppLovin has consistently been one of Pixelberry's top monetization partners, paying out strong CPMs and serving stable, high-quality ads. Its customer support has been impressive, offering proactive support and coming up with creative ways to optimize our performance.”
Max Doty, 3rd Party Monetization Lead, Pixelberry
AppLovin offers all ad formats (native, video/graphic interstitial, and rewarded video) to allow developers to optimize the ad format type for the best user experience and increased monetization. AppLovin has grown its business fast with a focus on a strong product and a quality service. The company offers ad creative services in-house, and a fully managed service for advertisers. This means advertisers reap the benefits of creative and account optimization working together, and that the service can manage down-funnel goals that are focused on ROI.
Sign-up is fast and takes less than a minute. Just go to the AppLovin sign up page, and make sure to note that you are a developer in the sign-up field. Once sign up is completed, approval is immediate -- you’ll receive a welcome email. Then simply click “login” on the AppLovin site to login, and from there integrate the AppLovin SDK (https://applovin.com/index#fireosIntegration) and get any additional support you might need.
If you have published an app on Amazon that uses v1.0 of the Facebook Platform API, you have until April 30, 2015 to ensure your app works properly with v2.0 of the API. Beginning April 30, v1.0 API requests will be processed as v2.0 API requests. This may break your app’s functionality unless it is built with a recent version of the Facebook SDK or you have custom code that explicitly calls v2.0 of the API (or higher).
Detailed information about the nature and scope of this update by Facebook is available from their Facebook Platform Upgrade Guide. You can get specifics on the migration process from Facebook’s Upgrading from v1.0 to v2.0 page.
Whenever a public API is updated, there is the potential to break applications that rely on it. API providers want to avoid this, of course, so they usually do two things. First, they assign a unique version number to each release, so developers can be specific about which functionality we are requesting. Second, they support both old and new API versions simultaneously, for a time, allowing our apps to continue to function until we can upgrade them to use the newest API.
Facebook did both of these. They first released their Platform API in April 2010, updating it several times since then and always attaching a new version number to each release. They have also continued to support previous API versions, so even if a developer were slow to upgrade, his or her apps would continue to work as expected.
That finally changes on April 30, 2015. That’s the day that Facebook will officially turn off support for v1.0 of the Facebook Platform API. Versions 2.0, 2.1, 2.2, and 2.3 of the API are already available (and have been for some time), so starting April 30, new and existing apps will be expected to use one of these versions, if they don’t already.
Luckily for most developers, Facebook provides SDKs for several platforms and languages, which makes handling API versions largely automatic. If you develop your app using a recent version of one of these SDKs, chances are you will not be affected when the Facebook Platform API v1.0 is deprecated. See Facebook’s Platform Versioning page for more information.
If you did not build your app using a recent Facebook SDK, or you have custom code that constructs unversioned API requests, your app may break on April 30. There are several significant differences between v1.0 and v2.0 of the API besides functional changes and improvements, including updates to permissions and user login. You should review the complete list on Facebook’s Upgrading from v1.0 to v2.0 page. There you will find detailed documentation explaining the impact of every change, how to adjust your app to deal with them, and how to invoke versioned calls manually if you still prefer not to use a Facebook SDK.
Here are just a few of the areas affected by the migration:
Unless you know for sure that your app uses v2.0 or later of the Facebook Platform API, you should assume that it will require an update. However, API v2.0 is used by default by Facebook’s Android SDK starting with version 3.14, so if you built your app after April 2014 using that SDK or a later version of it, no update is needed.
Keep in mind that v2.0 of the Facebook Platform API is itself scheduled to be deprecated eventually; after April 30 it will simply be the oldest version still supported. Facebook has committed to maintain each API version for not less than two years after it is introduced. See the Facebook Platform Changelog for more information.
If you believe your Amazon mobile app or game may be affected by Facebook’s deprecation of it’s v1.0 API, it is highly recommended that you visit the version-specific upgrade page mentioned above, or the more general Facebook Platform Upgrade Guide.

Since its launch in March 2011, over 16,000 apps have been launched on TestDrive, giving customers the experience of running the app and discovering new features before committing to purchase. However, with the increasing use of 'free to play' business models, we have seen a significant decline in customers using TestDrive, and effective 15th April 2015, we will decommission the TestDrive service.
Nothing – it’s just the TestDrive service that is being decommissioned. Apps that are currently using TestDrive will still be available and promoted in the Appstore, but without TestDrive functionality. The TestDrive category will be removed from the Appstore client, and we will not be enabling TestDrive for new app submissions.
Thank you for your continued support of the Amazon Appstore. If you have any questions, please contact us.
