Migrate Your Existing Web App (Fire TV)
Amazon Fire TV supports HTML5 web apps. If you have an existing web app that you want to make available on Fire TV, review the following checklist for migrating your web app to the Fire TV platform.
If you are developing a new web app instead of migrating an existing app, see Getting Started with Web Apps.
Before you begin, review the Design and User Experience Guidelines for details about designing your app for the 10-foot User Interface experience.

|Plays video||Make sure your UI is the proper state when your app regains focus. Note that the video playback is automatically paused when your app loses focus.

In addition, be sure to select the Prevent Sleep for Video Playback check box when submitting your app. This disables the Fire TV screensaver while your app plays videos.
