Access ordered images and video in same Cursor

Question

I\'m using the android.content.CursorLoader class to create two Cursor objects to access media stored on the user of my app\'s device. I\'d like to

Answer 1

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();
