title: ADB connecton to Android TV / Nvidia Shield TV?
body: <p>I try to send ADB commands from my Android mobile device (SGS5) to my Android TV (Nvidia Shield TV). I always get:</p>
  
  <pre><code>    error:device offline
  </code></pre>
  
  <p>or </p>
  
  <pre><code>    error:device unauthorized
  </code></pre>
  
  <p>With Windows or Mac the ADB connection works but not with an Android device.</p>
  
  <p>I did the following:</p>
  
  <ul>
  <li>Disable/enable debug mode</li>
  <li>Used USB cable</li>
  <li>Used Wifi</li>
  <li>rebooted all devices</li>
  <li>adb kill-server / adb start-server</li>
  <li>adb usb</li>
  </ul>
  
  <p>No success.</p>
  
  <p>Is it possible to connect an Android device (mobile/tablet) over ADB with Android TV (e.g Nvidia Shield TV) ?</p>
  
  <p>Mobile phone -> adb -> Shield TV</p>
