Access ordered images and video in same Cursor

After lots of research and playing around with source code, I’m finally a bit more familiar with the Android filesystem. To get a single Cursor which can access information about both Images and Video I used the following:

// Get relevant columns for use later.
String[] projection = {
    MediaStore.Files.FileColumns._ID, 
    MediaStore.Files.FileColumns.DATA,
    MediaStore.Files.FileColumns.DATE_ADDED,
    MediaStore.Files.FileColumns.MEDIA_TYPE,
    MediaStore.Files.FileColumns.MIME_TYPE,
    MediaStore.Files.FileColumns.TITLE
};

// Return only video and image metadata.
String selection = MediaStore.Files.FileColumns.MEDIA_TYPE + "="
         + MediaStore.Files.FileColumns.MEDIA_TYPE_IMAGE 
         + " OR "
         + MediaStore.Files.FileColumns.MEDIA_TYPE + "="
         + MediaStore.Files.FileColumns.MEDIA_TYPE_VIDEO;

Uri queryUri = MediaStore.Files.getContentUri("external");

CursorLoader cursorLoader = new CursorLoader(
    this,
    queryUri,
    projection,
    selection,
    null, // Selection args (none).
    MediaStore.Files.FileColumns.DATE_ADDED + " DESC" // Sort order.
  );

Cursor cursor = cursorLoader.loadInBackground();
