title: How to create updateable COSU App on Android TV [STB]
body: <p>I need some help with my app that I build for Android TV.</p>
  
  <ol>
  <li><p>I already make a COSU app for Android TV, but the problem is I need to use adb shell to make my app as device owner. Is there a way to make my app as device owner programmatically? Because I will install my app in +100 STB devices. I tried a method from <a href="https://stackoverflow.com/questions/40359917/how-to-make-my-app-device-owner-without-nfc-and-adb-shell-command">SO answer</a>, but it's not working.</p></li>
  <li><p>I still can't figure it out how to update my app later if there is a new version of my app, because like it said in <a href="https://stackoverflow.com/questions/47955252/android-management-api-cosu-on-androidtv">here</a>, I can't use Android Management API on Android TV and also I think I can't use Google Play to update a COSU app. Is there a better approach to update my app?</p></li>
  </ol>
  
  <p>Need help.
  Thank you.</p>
