I'm just trying to get a simple "Hello, world!" style app to run with the new Chromecast SDK. Here's the step-by-step I'm following:
https://developers.google.com/cast/docs/chrome_sender
To achieve minimal setup, I'm attempting to wire it up via a Chrome App (App, not Extension) as the Sender, and using chrome.cast.media.DEFAULT_MEDIA_RECEIVER_APP_ID as the AppID (as mentioned in the tutorial).
It seems to fall apart somewhere between Initialization and Launch. My call to chrome.cast.initialize succeeds, but when receiverListener gets invoked, the result is always "unavailable". If I attempt to call chrome.cast.requestSession, it invokes the error handler with an error code of "receiver_unavailable".
A few things:
- I've paid $5 to Google for a Developer account and registered my device
- Note: My applications list is still empty, is this a problem?
- I've reconfigured the Chromecast device to send the serial number when retrieving updates
- I've rebooted the Chromecast several times (from my Android app)
- The Chromecast is idle on-screen with landscapes flashing beautifully
- My laptop is on the same wireless network, using a basic Linksys router
- It doesn't work if I use "YouTube" or "Netflix" as the AppID either
Any other ideas? Please help! :)
Try the two Chrome sender apps here:
https://github.com/googlecast/CastHelloVideo-chrome https://github.com/googlecast/CastVideos-chrome
on your own server. Or you can try

If this works for you, then your Chromecast is good and your Chrome and Cast extension are good.
When you want to switch to your own app ID, you need to make sure they're ready in the Developer Console: https://cast.google.com/publish/.
Special thanks to @ssgg for leading me to this one.
In Windows 7, the shared network must be configured as Home or Work (not Public) Network. I re-configured it, rebooted my laptop, and it works like a charm!

Two other samples to help:
https://github.com/googlecast/cast-custom-receiver
https://github.com/googlecast/cast-sender-tool-chrome
(optionally use the media server to serve media to receiver - https://github.com/googlecast/cast-support-media-server)
If you are using windows and have multiple NIC's active be aware that this is a bug in Chrome with multiple NICs, it has been fixed in Chrome 33. You can either switch to 33, or use a workaround --> go into Network & Sharing Center -> Change Adapter Settings -> Alt-N to bring up "Advanced" Menu -> Advanced Settings, then move the Wi-Fi adapter to the top of the list.
i had the same Issues except that i could see my Chromecast from the Google Cast extension but never from the Sender App. I've tried all of the tips from the answers, plus the hints from the Google Cast Support Page. Using Chrome 33 finaly solved the issue.
@Krispy: thanks for guiding me to the Solution.
As you may all know by now, on Windows 7 this is an known problem. Chrome sender applications don't find the ChromeCast receiver. In the GitHub examples you get the "receiver list empty" message. In the ChromeCast issue tracker, this is known as issue 159.
One more issue that might lead to "Receiver Unavailable" is that you using non-published application. For this reason any chromecast device must be manually registered in the same interface where you getting APP_ID as a special device used for development reasons. Otherwise device could not reach non-published application with "Receiver Unavailable" error in result.
