Chromecast android app is not discovering custom receiver

I wrote a java chromecast receiver app which accepts M-SEARCH broadcast messages and responds with HTTP/1.1 200 message. Android app also invokes device-desc.xml files once the response is sent. But android app doesn't show the receiver name. But Fling application (https://github.com/entertailion/Fling) is able to discover the receiver without any issue.

Any help would be greatly appreciated.

Request from Chromecast android app

Solution

  • If you are using the official Android SDK, you need to know that the discovery method is now based on mDNS and not UPnP any more.
