title: Do I need to publish to the play store to cast to chromecast?
body: <p>I'm trying to cast to a chromecast with my android app. I have followed all the steps here. <a href="https://developers.google.com/cast/docs/developers" rel="nofollow noreferrer">https://developers.google.com/cast/docs/developers</a> </p>
  
  <p>I published the app in the cast developer console and got the published app id. I also tried with the public ones, but the cast button simply won't appear. </p>
  
  <p>Chromecast and device are both connected to the same wifi.         </p>
  
  <p>It works if I connect within the options in android's upper panel, but I need it inside the app.
  I don't know what I'm missing. That's why I'm thinking this might be the problem. That the app is not in playstore. I have no intention to publish it, so I cannot try just to test.</p>
  
  <p>Thank you for your help!                       </p>
