Is it possible to view - docs/ppts (saved in google drive) and play- videos (saved in google drive) in a custom input dialog?

I have a custom input activity which has few radio buttons (lets say “Doc”, “PPT”, “Videos”) based on user selection i want to display respective Doc/PPt/video in the input dialog itself. The files are stored in Google drive. Is it possible to play a video in custom input dialog. or is there any other way to link it to play or view the docs/ppts.

I tried with start process activity, used open browser by passing the urls in it but i want to play a video in a custom input dialog only. if there is a way plz help me to continue with it.
