title: is GuidedStepFragment for android Mobile or only android TV?
body: <p>The fragment is included in <code>android.support.v17.leanback.app.GuidedStepFragment</code> which is apart of Leanback library. </p>
  
  <p>I think Leanback is for Android TV, will <code>GuidedStepFragment</code> work if i try to implement it in a mobile device?</p>
  
  <p>Here is an example of the fragment in action: <a href="https://youtu.be/RhXuihvQ4Lg" rel="nofollow">https://youtu.be/RhXuihvQ4Lg</a></p>
