Hello

I'am implementing a custom gallery for my app which allows users to select multiple images at once. The user is first shown a list of valid photo albums and then when the user selects the album only the images in that album should be displayed. The code before should only load valid photo albums.

Java

@Override
	public Loader<Cursor> onCreateLoader(int arg0, Bundle arg1) {
		
	   final String[] projection = {
	            MediaStore.Images.Media.BUCKET_DISPLAY_NAME };

		final String orderBy = MediaStore.Images.Media.DATE_ADDED;
		
		return new CursorLoader(getActivity(),MediaStore.Images.Media.EXTERNAL_CONTENT_URI, projection, null, null, orderBy);
	}

The problem is, the cursor loads all images, I just want a list of bucket names. How can I go about this?

Thanks.

Here is my code:

C#

private static final Uri mBaseUri = Files.getContentUri(EXTERNAL_MEDIA);
private static final String[] PROJECTION_BUCKET = {
            ImageColumns.BUCKET_ID,
            FileColumns.MEDIA_TYPE,
            ImageColumns.BUCKET_DISPLAY_NAME };
Cursor cursor = mApplication.getContentResolver().query(
                mBaseUri, PROJECTION_BUCKET, null, null, null);

Have a try.
