Name not found exception when updating to latest casting library version

Question

So I'm trying to update the chrome cast library (from 1.x to 2.x) in my app and casting is working but when I try to add this to my manifest to enable notifications I get a package name not found exception. The reason I've targeted this as the problem is that I can cast perfectly when I remove this from my manifest. I also wanted to add that I got this manifest declaration from the example here.

 <receiver android:name="com.google.android.libraries.cast.companionlibrary.remotecontrol.VideoIntentReceiver" >
    <intent-filter>
      <action android:name="android.media.AUDIO_BECOMING_NOISY" />
      <action android:name="android.intent.action.MEDIA_BUTTON" />
      <action android:name="com.google.android.libraries.cast.companionlibrary.action.toggleplayback" />
      <action android:name="com.google.android.libraries.cast.companionlibrary.action.stop" />
      <action android:name="com.google.android.libraries.cast.companionlibrary.action.rewind" />
    </intent-filter>
  </receiver>

  <service
      android:name="com.google.android.libraries.cast.companionlibrary.notification.VideoCastNotificationService"
      android:exported="false" >
    <intent-filter>
      <action android:name="com.google.android.libraries.cast.companionlibrary.action.notificationvisibility" />
    </intent-filter>
  </service>

  <service android:name="com.google.android.libraries.cast.companionlibrary.cast.reconnection.ReconnectionService"/>

Here's the full error.

Here's how I'm initializing the VCM in my applicaiton:

VideoCastManager.initialize(this,
 new CastConfiguration.Builder(BuildConfig.CAST_APP_ID).enableNotification()
 .enableLockScreen()
 .enableWifiReconnection()
 .enableCaptionManagement()
 .enableDebug()
 .addNotificationAction(CastConfiguration.NOTIFICATION_ACTION_PLAY_PAUSE, true)
 .build());
