opening an image using Intent.ACTION_PICK

ACTION_PICK is to allow a user to select an image from any of the installed apps which registered for such an action. It is not possible to specify from which album to select. It is at the user discretion to decide which app to use and to browse to the desired album to select the photo.

So taking out the folder parameter, you can try this:

Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, REQUEST_CODE_LOAD_IMAGE);

And in the onActivityResult, besides the RESULT_OK, you should also check for data.getData() != null, as an app could close correctly (not cancelling) without returning an image at all.
