How to Read MMS Data in Android? (5 answers)

Closed 6 years ago.

Google is providing a very nice documentation of the contacts provider in Android API. (You can see it HERE. It has a full details of all tables and columns names used in these databases. I tried to look for the same for sms and mms databases (which are located in mmssms.db) but I could not see any documentation for that. So my questions are:

• First, is it true that there is no such documentation ?
• If yes, why google tried to keep this away from us ?
• And, in your opinion, how can I get more details about the tables used and a description of each column in that table (i.e. what each column is used for).

By the way, I need this information to write a java program that will read sms/mms data. You can assume that I already got mmssms.db file.

Thanks, and I appreciate any help.
