Hi Jack,
Thanks for getting in touch to clarify on your use case. Currently, the IMA SDK for Android does not support any TV-based implementations, so we would not be able to recommend on any native workaround.
You might want to try the HTML5 SDK instead, and utilize a functionality called
custom playback to provide a cross-platform experience to native TV app users. In essence, your app would be opening a website containing an IMA implementation, so here you would want to adapt the page's UI and UX to match that of your app.
