[SOLVED] Android Chromecast sender app, cast button doesn't appear in action bar

I went through this https://developers.google.com/cast/docs/android_sender up to "Handling device selection" paragraph including. I expect that cast button should appear in action bar, but it isn't. And I suppose that Chromecast device was not been discovered.

I have real Chromecast device and I registered it in Google Cast SDK Developer Console. And I suppose that device whitelisted because I have access to http:// chromecast_device_ip:9222

I set "checked" for option "Send this Chromecast's serial number when checking for updates" 2 days ago. And I rebooted the device after that.

Also, I registered an application in Google Cast SDK Developer Console. But it's not published yet. I think it can't be the reason, isn't it?

I use DEFAULT_MEDIA_RECEIVER_APPLICATION_ID as APP_ID. But I also tried APP_ID of my registered application.

I tried sample apps from GitHub: https://github.com/googlecast Cast Tic-Tac-Toe, CastVideos-android, MediaRouter-Cast-Button-android. And in all sample apps was the same problem. Cast button doesn't appear.

In DIAL CLient app (author entertailion) all work fine. But I'm not sure that it is what I need to implement Chromecast sender app...

here is my code:

Also, I got next errors in LogCat. But it not crashes app.

UPDATE

Leon Nicholls said that it is known discovery issue in the previous release of the Cast SDK. A new version 5.0.89 of Google Play Services should work fine.

I suppose that I have an old release of the Cast SDK. In google-play-services_lib/AndroidManifest.xml I see next

<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:versionCode="5077000" android:versionName="5.0.77-000"

But I have no idea how to update it. In Android SDK Manager Google Play Services marked as installed and there is nothing to update....
