The fragment is included in android.support.v17.leanback.app.GuidedStepFragment which is apart of Leanback library.
I think Leanback is for Android TV, will GuidedStepFragment work if i try to implement it in a mobile device?
Here is an example of the fragment in action: https://youtu.be/RhXuihvQ4Lg
Leanback is a library specifically designed for TV, as stated on developer.android.com:
v17 Leanback Library
The android.support.v17.leanback package provides APIs to support building user interfaces on TV devices. It
provides a number of important widgets for TV apps.
But Nothing prevent you to use the widgets available in the library in your mobile app for Android 4.2 and higher. You will probably have to make some adaptations since the Android TV have a different kind of interaction (TV remote and game controller) compared to the mobile device.
You can make a quick test of the GuidedStepFragment running the Android TV Leanback example on your mobile device and selecting:

I have been developed cinema android application in java that show some movies and series the application is work very good
know I want to make that app work on smart TV is there is any way to do that or should I develop another app specified for TV
Unfortunately most of Smart TV are based on web technologies (HTML5, CSS JavaScript) but some manufacturers have been including Android TV as TV platform (Sony, Phillips, Thompson...)
Depending of your development, you can migrate directly (or making few changes) your current app to the Android TV requirements
For other TV platforms, like LG (webos) Samsung (Tizen) etc you will need to create your app using HTML, CSS, JavaScript and use the SDK to access native functions

I'm trying to develop an app using TVInputFramework. In android SDK all API s are not available. I want use HdmiControlService (a system service) in my app. The only way is using internal API or hidden API in my app.
How to develop apps using these API s.
Is there any Tutorials.
Can i use my android studio to develop this kind of app.
Thanks in advance
There is a mini-guide on how to use TIF in Developing a TV Input Service.
Create a TV Input Service Using the TIF Companion Library
The TIF Companion Library is a framework that provides extensible
implementations of common TV input service features. Use the TIF
Companion Library to quickly and easily create your own TV input
service that follows best practices for Android TV.
There is even a sample app in Github called Sample Android TV Channel App (TV Input) using TIF.
You need to build your own Android Sdk and produce an android.jar file.

After a lot of searching I cannot find the answer to this. My fire tv app was rejected by Amazon because the app doesn't appear under settings > manage installed devices in Fire OS. What is odd is this is not an issue for Android TV and I can see it in the app manager in setting there. Any idea what I could be doing wrong for the fire tv devices? Amazon has been zero help.
Thanks!
The issue is amazon only supports part of the Android Leanback Support Library. How we are supposed to know everything it does or does not support is unknown to me and is a really poor implementation on Amazon's part.
https://developer.amazon.com/public/solutions/devices/fire-tv/docs/amazon-fire-tv-differences-from-android-tv-development
"Fire TV supports some but not all of Android’s Leanback Support Library. Fire TV uses TV-specific UI components from Leanback, and Leanback widgets will work, but if you tag an activity for the Leanback Launcher, the activity will not work. Specifically, Fire TV does not acknowledge the activity category CATEGORY_LEANBACK_LAUNCHER."
I would recommend being cautious of your reliance on android leanback support with fire tv which really hurts code reusablity for software developers. Your app will still work but you may be missing the entry in settings like my current issue. Hopefully Amazon adds better support for the leanback support library going forward.
If i want to write an app that supports all casting mediums mentioned in the title of this question, do i need to implement all the sdk's separately or do any of the sdk's have a way to wrap the functionality of the other ones?
Each SDK is specifically for that protocol / product. Vizio, Chromecast, and Android TV all support Google Cast so you can use one SDK for that.
One Cast works, you can use this guide to learn how to also support Samsung Smart View.
I was requested to develop an Amazon Fire TV app, but I find difficult to understand the steps required to get on track.
As specified by the Amazon documentation, the previously available Fire TV SDK add-on is now deprecated, and they suggest to just use the Android v17 Leanback Library.
To date, I do not have (yet) a Fire TV, and the official documentation is very poor and rather confused; I'm not able – then – to understand whether "pure" Android TV apps are fully compatible with Fire OS 5, so that developing for the Fire TV is actually the same as developing for a generic Amazon TV (from the SDK, to the virtual testing process).
In the case it isn't, what are the different steps I have to take into account?
You should start with using Android v17 Leanback Library. There is a sample app available from Google that uses leanback library. Few things you might need to check for firetv like speech recognition (SearchFragment in the leanback library) is currently unsupported
Fire OS 5 includes both support for Android TV functionality and the
leanback support library. Speech recognition (SearchFragment in the
leanback library) is currently unsupported.
and global search which is not customizable for individual apps for firetv
Global search is provided system-wide and is not customizable for
individual apps. Developers may implement their own in-app search, but
it is not included in the global search function.
Also try to follow pre-submission assessment guidelines and developer FAQs when developing for a firetv.
