As stated in Google cast Developer Guide, I need a sender application and a receiver application in order to publish an app for Chromecast. My app uses Presentation class to show contents on Chromecast when the device is mirrored to the Chromecast. Yes, the app only works on devices which can cast its screen onto Chromecast. I am not using any kind of receiver application for my app. Can I still publish my app for ChromeCast so that it can appear in apps section for Chromecast?
