In the previous episode of this series we discussed how to create the main interface of our Leanback-enabled project through the BrowseFragment. Now let’s take a closer look into the Presenter class. The Presenter class allows us to define the look and feel of our Leanback-enabled app without editing the underlying data structure.
The Leanback template we created was built following a custom version of the common development pattern, Model-view-controller (MVC), in which the Presenter class acts as the View. The Presenters are passed to the ArrayObjectAdapter as arguments and define how the content of the Adapter should be displayed
The Leanback approach provides a variety of predefined Presenters:
Implementing the Presenters are quite similar: they all follow the ViewHolder pattern and are mostly composed by Custom Views with methods to set the fields of the views. Let’s take a close look at the customizing the CardPresenter as an example:[Read More]
In the previous episode of this series we discussed the anatomy of a Leanback-enabled Android App for Amazon Fire TV, discovering what its main components are and how they are tightly tied to the Media Streaming Interaction Model.
We’ll now take a close look into the first and most basic component of an Android App for Amazon Fire TV: the BrowseFragment.
After we launch our freshly created TV Android App, built using the Android Studio App Wizard, we will encounter an interface that will look very similar to this:
In the first part of this series we learned how easy is to create a new Android App for Amazon Fire TV and how to run it for the first time using the Android Studio Wizard for Leanback-Enabled apps in a matter of a few minutes.
We’ll now deep dive into what the main components of this app are and how they interact with each other.
After we have created a new TV project using the Android Studio Wizard, we can notice that the wizard has automatically included some libraries in our project dependencies.[Read More]

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 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.[Read More]
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.co.uk, Amazon Fire tablets, and Amazon Appstore on Android devices.
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.
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.[Read More]

On November 3rd 2015 300+ attendees, two tracks about monetization and gaming, 13 sessions, multiple guest speakers and the Amazon Appstore evangelists animated a very successful developer-focused conference: the Amazon Appstore Developer Summit 2015, which took place at CodeNode, London.
The Amazon Appstore Developer Summit focused around unique insights into the Amazon Appstore ecosystem, emerging user interfaces and devices that are driving new user behaviors, like Fire TV and Amazon Echo, and new business models like Amazon Underground and Merch, which are opening up opportunities for customers and the developer community.
Here you can find the recordings of all the sessions, complete with slides, organized by topic:[Read More]
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.[Read More]
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.[Read More]
Amazon Underground is a new app for Android phones where customers can access over 1,500 free versions of apps and games that normally cost money to download and play (including unlimited, free in-app items). Amazon Underground launched in August of 2015 for customers in the US, UK, Germany and France. Starting today, Amazon Underground is available in 16 additional countries and territories including Italy and Spain, opening up new and exciting opportunities for mobile developers to reach an even broader audience.
Amazon Underground customers will find free versions of popular premium titles like Office Suite Professional 8 and Fruit Ninja and popular titles with in-app purchases like Frozen Free Fall, Star Wars Rebels: Recon Missions, Angry Birds Slingshot Stella, and many more. Any developer can submit their app, which means more apps and games will be added to Underground all the time.[Read More]
