Getting Sender for a Downloaded MMS in Android

Might be simpler way to do this, but it works.

If you are using a ContentObserver in Android to detect when there are new downloaded MMS messages, then you might have noticed that it is apparently not possible to get the sender information.  A ton of stuff is available, but not the sender.   However, the sender is provided when the MMS notification is received - and you can get this notification by using a BroadcastReceiver.

The only way I've found to get the sender once the MMS downloads is to use a separate database that stores the (transactionID, sender) when the MMS notification is received.  Then, once the MMS has downloaded, you can use the transactionID which *is* available and look up the sender in the separate database.
