Chromecast “StartApplicationRequest failed with status: -4”

问题

I've set up the Chromecast SDK, whitelisted my device, and am running web servers at the URLs I provided in the whitelist request.

The chromecast tic tac toe app works fine with the default app id "TicTacToe", however changing it to my own: "1813060e-33c5-41dc-b356-0d2bad12497f" or "1813060e-33c5-41dc-b356-0d2bad12497f_1" does not work.

The server url is up and running at http://chromecast.clockworkmod.com/, but no requests are being made to it by Chromecast. The chromecast doesn't display anything. However I get a few errors in the log.

Here is the logcat.

W/StartSessionTask(15590): StartApplicationRequest failed with status: -4 E/ApplicationSession(15590): StartSessionTask failed with error: failed to start application: request failed D/GameActivity(15590): start session failed: failed to start application: request failed

I've also tried using the internal app id with the dev url I had provided, http://192.168.1.2:3000/

I found the answer here:

unable to cast to personal whitelisted receiver app

Using the Chromecast app on my Macbook, I went into Settings.

Send serial number when Checking for updates
Reboot device the device using the Mac update app

This resolved the error for me. The chromecast doesn't know if it is whitelisted unless you send the serial during update checks.

I think I see what's missing! In your receiver you gave a link to, you have:

var receiver = new cast.receiver.Receiver(
    'GoogleCastSampleApp', 
    [cast.receiver.RemoteMedia.NAMESPACE],
    "",
    5);

But it should be (fill in the 'YOUR APP ID HERE' with your App ID)

var receiver = new cast.receiver.Receiver(
    'YOUR APP ID HERE', 
    [cast.receiver.RemoteMedia.NAMESPACE],
    "",
    5);

I am running into the same error as well. I after setting the Chromecast to send the serial when checking for updates I was finally able to access the debugger one port 9222. Unfortunately, I don't see anything happen on the Chromecast at all when I select it from the device list on my Nexus and try sending one of the demo videos.

Something I noticed and I don't know it makes difference or not but if you whitelist a domain in the GoogleCast extension for Chrome and you include the "http://" it will cause the injection to not work. I wonder if this is the problem with the look up that the Chromecast performs as I submitted my URLs to Google with the http:// prepended. Again I am not sure this should really make a difference but I plan on trying to resubmit the URLs just to see.

Install cURL in your windows machine from here

Now make sure that your device and laptop are in same network.

Now go to command prompt, type curl -d "" http://:8008/apps/YouTube

there If it gets casted automatically to TV then instead of YouTube put your appid and try.

If not then your router is blocking some traffic.
