Hi, I'm working on handling errors while receiving an MMS (listed in TODO as : "Error cases should handled and reported to the application layer." in MMS Reception section). What kind of error do you want to report to the application : generic MMS reception error such as "Unable to decode message", "Unable to download message" ... or more accurate error (error code, "HTTP error XXX", "Communication error while downloading message"... ) ? Since the reception is automatically performed, there is no D-Bus reply msg to use to send error back to the application ! I cannot always handle the error in 'Message' interface since the D-Bus object (associated to the message) does not exist before having downloaded the entire message. More generally, how to handle errors that occurs before the message D-Bus object has been published ? Should I define a new signal ("MessageError") in 'Service' interface to report errors ? What kind of information the reported error should contain ? the sender (if the notification has been decoded), the meta file path (if available) ... ? Thanks in advance, Regards, Ronald
