the class PduPersister method persistData.

/**
 * Save data of the part into storage. The source data may be given
 * by a byte[] or a Uri. If it's a byte[], directly save it
 * into storage, otherwise load source data from the dataUri and then
 * save it. If the data is an image, we may scale down it according
 * to user preference.
 *
 * @param part The PDU part which contains data to be saved.
 * @param uri The URI of the part.
 * @param contentType The MIME type of the part.
 * @param preOpenedFiles if not null, a map of preopened InputStreams for the parts.
 * @throws MmsException Cannot find source data or error occurred
 *         while saving the data.
