title: DialogFragment vs Activity with Dialog theme
body: <p>I understand that both Dialog-fragment and Activity with Dialog theme can be used to create Dialog in Android. I also understand that both they survive during Orientation changed.</p>
  
  <p>My question is can I always use Activity with Dialog theme for all my dialogs? Is there any case I have to use DialogFragment instead of Activity with dialog theme?</p>
  
  <p>Thank you!</p>
