I am attempting to add Google Cast functionality to my audio apps. I have created a simple test app to figure it out. I have the cast button working, but currently, it is only displaying my TV's Chromecast and not the Nest Mini I also have on the network. I know this device is available on the network because it shows up as a cast option in YouTube Music. From reading the documentation on audio only devices, the only extra step I saw was to check the box next to "Supports casting to audio only devices" in my apps settings on Google Cast SDK Developer Console and to make sure I have the id set in my options provider. Here is my options provider:
class CastOptionsProvider: OptionsProvider {
override fun getCastOptions(context: Context): CastOptions {
return CastOptions.Builder()
.setReceiverApplicationId(context.getString(R.string.app_id))
.build()
}
override fun getAdditionalSessionProviders(context: Context): MutableList<SessionProvider> {
return mutableListOf()
}
It is defined in the manifest like this:
<meta-data
android:name="com.google.android.gms.cast.framework.OPTIONS_PROVIDER_CLASS_NAME"
android:value="com.example.casttest.CastOptionsProvider"/>
I am using the ID for my app from the Google Cast SDK site.
