The easiest way to mirror your phone to your TV
Most media apps offer Google Cast support these days, but it’s always nice to have screen mirroring available for situations that call for it.
The Google Cast SDK was released on February 3, 2014, allowing third parties to modify their software to support the protocol.
But the SDK of Google is only for Android TV OS and Google Chromecast, and the Android TV OS is not popular. So if your receive device is a normal android device or a linux device or a windows device, you can not use the SDK released by Google.
