<p>
  Android offers a rich user experience that's optimized for apps running on large screen devices,
  such as high-definition televisions. Apps on TV offer new opportunities to delight your users
  from the comfort of their couch.
</p>

<p>
  TV apps use the same structure as those for phones and tablets. This approach means you can
  create new TV apps based on what you already know about building apps for Android, or extend your
  existing apps to also run on TV devices. However, the user interaction model for TV is
  substantially different from phone and tablet devices. In order to make your app successful on TV
  devices, you must design new layouts that can be easily understood from 10 feet away, and provide
  navigation that works with just a directional pad and a select button.
</p>

<p>
  This class describes how to start building apps for TV, including setting up your development
  environment, basic requirements for layouts and navigation, as well as guidance on how to handle
  hardware features that are not typically available on TV devices.
</p>

<p class="note">
  <strong>Note:</strong> You are encouraged to use <a href=
  "{@docRoot}sdk/installing/studio.html">Android Studio</a> for building TV apps, because it
  provides project setup, library inclusion, and packaging conveniences. This training assumes you
  are using Android Studio.
