Question

I’m in a very big trouble in building a simple custom SMS/MMS content provider wrapper class as long as it doesn’t exist an official one for the android platform.
Obviously, to get data, i query on the “content://sms” and “content://mms” content provider using a cursor.

I found it fairly simple with SMS, because the columns names are quite intelligible and contains all data that a typical programmer needs in his application (“person” to get the sms sender/receiver contact id, “address” to get the sender/receiver phone number, “type” to get if the sms is an inbox, outbox, draft, sended sms etc…)

Unfortunately with MMS i’ve found a lot of trouble. The columns has unintelligible names (ex. “d_tm”, “ct_cls”, “retr_st”, “d_rpt” etc.) and basic informations that i need, such as contact id, phone number, the type of the mms etc… seems to miss.

How can i get this information over the MMS?
I searched over all the 32 columns of the content provider but i didn’t found what i need.

Thanks in advance!

P.S.
I know that google advise to avoid this kind of “low-level” operation over content providers that doesn’t have a series of official class to access them, but i imagine that software house that operates in sms/mms management such as HandCent or Go Dev team, have built their own content provider using the same approach i’m using too.
Am i right or it exists unofficial libraries to manage SMS/MMS?

Thanks!

Answer 1

I googled a little bit more and finally i found that the correct way to get information like contact_id, phone number, type etc. about MMSs, is to open the content provider to the following

 URI: "content://mms/{MmsId}/addr" 

({MmsId} is the MMS “_id” column value).

Here i found all information i need.

Hope it helps!!!
