This class works in conjunction with NativeAppCallContentProvider to allow apps to attach binary attachments (e.g., images) to native dialogs launched via the FacebookDialog class. It stores attachments in temporary files and allows the Facebook application to retrieve them via the content provider.

Callers are generally not expected to need to use this class directly; see OpenGraphActionDialogBuilder.setImageAttachmentsForObject.setImageAttachmentsForObject(String, java.util.List) for an example of a function that will accept attachments, attach them to the native dialog call, and add them to the content provider automatically.
