Part 1: Deploy a “Hello World” Media Streaming App on Fire TV in a Few Minutes

Android is no longer just for Mobile devices. Even if it started as an OS designed for smartphones, it evolved during time. In 2011 with Android 3.0 Honeycomb, specifically designed for tablets, Android scaled up to bigger screens, and this changed the way users engaged with mobile devices. Recently, Android scaled up to an ever bigger screen: the TV.

All of a sudden, Android developers can start thinking about building native Android apps for a new and exciting use case, the 10-foot experience, where users sit down, relax and engage with content specifically designed for their TV.

Amazon Fire TV and Fire TV Stick are Android devices

Amazon Fire OS, which animates all the most recent Amazon devices like Fire tablets, Amazon Fire TV and Amazon Fire TV Stick, is based on Android 5.0 Lollipop. This means that Fire OS is capable of running full-fledged Android apps: 85% of Android apps submitted to the Amazon Appstore just work! If your app relies on the Android framework APIs and related support libraries, there’s a high chance it can run on Fire OS. You can test your APK on our online App Testing Service and discover in 90 seconds if your app is compatible with Fire OS! When it comes to Fire TV, we wanted to make life of developers easy. That’s the reason we decided to fully support the Android Leanback Support library. This make extremely easy for Android developers to deploy native media streaming apps for TV.

Let’s discover how.

We hear from many developers that getting apps discovered by customers is an important part of launch. Because of this feedback, we’re kicking off a new initiative to feature more UK developers on Amazon Appstore UK. To have your app considered, simply submit before June 10, 2016. We will review and select a number of newly published apps (submitted between April 20th and June 10th 2016) to be featured as part of an Appstore UK billboard. There will also be opportunities for stand out apps and games to be highlighted in additional placements on, Amazon Fire tablets, and Amazon Appstore on Android devices.

What Do You Need to Do?

  1. Register for a free Developer Account if you have not done so already
  2. Submit your new apps before June 10, 2016
  3. Complete THIS FORM  by June 10, 2016

Don't forget, we have an APK testing tool on our developer portal where you can find out in 90 seconds if your app is compatible. And from the apps testing so far, we see that 85% of Android apps just work without changes on Amazon devices.

How Will the Apps Be Selected?

For the featured placement on our UK Appstore, the Amazon team will review and select apps to be featured. (Disclaimer: submitted apps which are rejected during the Appstore review process will not qualify as entries. We will only consider apps that are newly published or approved for publishing. Only new apps submitted from April 20th  to June 10th 2016 will be considered). Once all apps have been reviewed, we will announce the selected developers via email.

We look forward to see your new apps on Amazon Appstore!

Design is one of the pillars of the success of a mobile app, along with the development process and the distribution channels. Defining how the users will interact with your app is as important as implementing the features of the app and integrating an efficient monetization model. Also, when it comes to designing an interface for a new interaction model like TV, a lot of the patterns that work well with smartphone and tablet interfaces needs to be rethought to take advantage of the big screen and the input model provided through the remote.

Optimize Your Android App User Interface for Fire, Fire HD 8 and Fire HD 10 Tablets

The new line of Fire tablets set an entirely new standard for low-cost tablets, with the Fire 7’’ Tablet being sold at less than $50. Amazon has already sold millions of tablets, so it’s a great time for you to submit your apps and games to the Amazon Appstore. In order to provide a great experience to users, the first thing you have to think about is the user interface (UI) of your app. Designing the UI and UX (user experience) of an app could become a very challenging and time-consuming task, but there are some simple steps that you can follow to make your app look great on the new Fire tablets. Also, keep in mind that Fire OS 5, available on all the new Fire tablets, is based on Android 5.1, so all the standard approaches to develop Android apps UI also apply to Fire OS apps!

In this post, we’ll deep dive into understanding screen resolution and density of Fire tablets, disclose the best strategies to properly create and size the layouts and graphical resources of your app, teach you how to provide a correctly-size app icon for Fire OS 5, and how to explicitly declare support for Fire tablets in your Android app manifest.

Amazon Underground allows developers to monetize 100% of the customers using their apps or games. Because apps and games are Actually Free on Underground, including in-app purchases, all customers need to do is download and start playing. Developers are paid by Amazon for every single minute their app is used by customers—rewarding player engagement and retention, rather than monetization effectiveness.
