How make VR video gallery in Unity in Android.. (GearVR)

Hey guys, I am relatively new to all of this and one of my coworkers at my new internship wants me to create a video gallery using the GearVR. So I figure there will be a script that finds all the videos that are on your phone then creates n (n being the number of videos on the Note 4) number of cubes (i guess resembling canvases) that have MovieTextures on them, these will then play once you look at them long enough. How do I search through the entire phone to find and play theses videos?

my bigget problem -> how access external video files in Unity in internal memory of S6 and play in GearVR (unity made project) ???

Thanks in advance for the help guys!

 

edit AndroidManifest.xml file add line
"<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />"
Hope this help!
