java.lang.ClassNotFoundException: Didn't find class "util.CastOptionsProvider"

Hi, I have a problem using the cast to Chromecast option.

When I call: PlayServicesUtils.checkGooglePlayServicesAvailability(this, googlePlayServicesAvailabilityRequestCode, this::initChromecast);

I receive the error:

java.lang.ClassNotFoundException: Didn’t find class “util.CastOptionsProvider”

That is caused by -

private Unit initChromecast() {
        new ChromecastYouTubePlayerContext(
                CastContext.getSharedInstance(this).getSessionManager(),
                new SimpleChromecastConnectionListener()
        );

        return Unit.INSTANCE;
    }

More precisely by CastContext.getSharedInstance.

I have to mention that if I remove the cast button, the player works just fine. Am i missing something?

I have to mention that in my build.gradle I have those lines:

implementation 'com.pierfrancescosoffritti.androidyoutubeplayer:core:8.0.1'
    implementation 'com.pierfrancescosoffritti.androidyoutubeplayer:chromecast-sender:0.15'

    implementation 'com.android.support:mediarouter-v7:26.1.0'
    implementation 'com.google.android.gms:play-services-cast-framework:15.0.1'

    implementation 'org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.2.50'

Thank you!

PS: the cast doesn’t work from the app existing in play store either. I have tested with youtube and I can cast to my Chromecast directly from their app.

Hello I have the same problem in java, I have the application in Google Cast SDK Developer Console. I throw the error E/CastContext: Failed to load module from Google Play services. Cast will not work properly. Might due to outdated Google Play services. Ignoring this failure silently. I’m new to learning. And I loved this library where you can control everything congratulations.

The fully qualified name of the implementation of OptionsProvider must be provided as a metadata in the AndroidManifest.xml with key com.google.android.gms.cast.framework.OPTIONS_PROVIDER_CLASS_NAME.

No worries - I am looking into it.
