There's a workaround that might be useful for some people - use the Shadowsocks app for Android TV. Because that app only accepts a JSON configuration file, you need to convert the Outline key to JSON.
- Take the following JSON file template:
{ "server":"YOUR-SERVER", "server_port":12345, "local_port":1080, "password":"YOUR-PASSWORD", "method":"chacha20-ietf-poly1305",
