I'm developing an app that has a BroadcastReceiver that listens for the WAP_PUSH_RECEIVED_ACTION and then attempts to download the content of the MMS using downloadMultimediaMessage().
However, this only works if the default messaging app (which is not mine) doesn't get to it first, since once the MMS is downloaded, the carrier usually deletes the MMS from its servers.
When this happens, I have to fallback to finding the downloaded MMS in Android's MMS Content Provider. The only reliable piece of information I have to find the MMS I'm looking for, is the Transaction ID I obtained from the WAP_PUSH_RECEIVED_ACTION notification, but for some reason, all Transaction IDs in the content provider are null.
How can I reliably find the MMS in the content provider using only the information I receive in my BroadcastReceiver?
