HI,Actually no, you can use the one that it's already developed for you to use. You can test it using this sample app:https://github.com/ooyala/android-sample-apps/tree/stable/ChromecastSampleAppIf you are really interested in creating your own receiver I recommend you to read the following:http://help.ooyala.com/video-platform/concepts/chromecast_overview_receiver_app.htmlAnd here's the repo for a custom receiver https://github.com/ooyala/chromecast-sample-receiver
