title: Pulling EXIF Data from ALL Photos on Device without opening or selecting them
body: <p>So I'm looking to take EXIF data from all photos on a device without manually opening or selecting the photo from Gallery. So far I've found a ton of ways to pull it from a single photo (with hardcoded file path). </p>
  
  <p>My question is, how do I access each photo without opening or selecting it, then gather EXIF data?
  My assumption was that I would have to access the phone's native photo directory through <code>Environment.DIRECTORY_PHOTOS</code>, then find some way to loop through all photos on that directory and gather the information I need. However, I haven't found a way to accomplish this.</p>
  
  <p>Is this possible? Or is there a better way to accomplish this? </p>
