Build a Simple Cast to TV Android app

I need a cast to tv android app in Android Studio(Java, Kotlin).
1-> Create a Button in MainActivity name Cast.
2-> On Button Pressed show a dialog list of All Casting Devices(TV) nearby.
3-> Connect With Casting Device(TV) on click list item
4-> When Connected play a video on Casting Device(TV)
5-> Just cast our App screen to TV not the whole phone or other Apps
or other queries we discuss in chat. Thanks
