Example gets stuck trying to discover Chromecast devices

[ryanheise]

When I run the example on my Google Pixel 3a, and click the Chromecast button, it shows a dialog where it searches for Chromecast devices. That dialog searches forever without success. The Chromecast is on, and other apps can discover it.

Did you change the receiverApplicationId in CastOptionsProvider in the android project?
You can use the default CC1AD845 receiver ID
After that the example worked for me

Thanks @MatthiasWissink . I only ran the example as is without checking it so I didn't spot that - @gianlucaparadise perhaps it would be a good idea for the default example in this repo to also use the default receiver ID?

[gianlucaparadise]

Did it work using the default receiver ID? The receiver ID of the example points to a custom web receiver that showcases the feature of the example sender.
If it worked with the default receiver ID, than there is a problem on the custom receiver and I can look into it.

[MatthiasWissink]

Yes, I have the example working with the default receiver ID. When using the one that comes in the repo, I get the same loading/searching issue as @ryanheise

[gianlucaparadise]

Can you please try again? I just published the custom receiver.

[MatthiasWissink]

Still the same behavior running the example as it is.
But I also saw that the receiver ID in example/android (D6760CCD) is different from the one in root/android (4F8B3483). Only using this ID or the default ID works.

@MatthiasWissink is there an Android equivalent to kGCKDefaultMediaReceiverApplicationID?

Edit:
Looks like there's DEFAULT_MEDIA_RECEIVER_APPLICATION_ID
Might open a PR to use these constants in example rather than D6760CCD / 4F8B3483 as mentioned.

The receiver ID of the example points to a custom web receiver that showcases the feature of the example sender.

@gianlucaparadise Care to share how to use the custom web receiver?
