SMS sent / delivered: how do you determine which SMS items belong to?

Question

In the stream How to track each status of a sent SMS? described how you can track the status of sent / delivered SMS via broadcast.

However, I did not find: how do you determine to which SMS the transmission relates? As far as I know, there seems to be no information in getResultData () and getResultExtras ().

My use case: I send several SMS in a loop one by one. I want to track delivery status / success for each message. How to find out which broadcast belongs to which message. (Delaying the delivery of each sms until I received a broadcast for each previous one is actually not an option).

Matthias,

Referring to the code in your related question. When you create an Intent that PendingIntent will run instead of just giving it an Action String , you can add additional information to it to determine which SMS it belongs to ...

 Intent sentIntent = new Intent(SENT); sentIntent.putExtra("smsNumber", someValue); PendingIntent sentPI = PendingIntent.getBroadcast(this, 0, sentIntent, FLAG_UPDATE_CURRENT); Intent deliveredIntent = new Intent(DELIVERED): deliveredIntent.putExtra("smsNumber", someValue); PendingIntent deliveredPI = PendingIntent.getBroadcast(this, 0, deliveredIntent, FLAG_UPDATE_CURRENT); 

Thus, you should be able to get the value "smsNumber" inside the BroadcastReceiver

Hope this helps!

Edit Matthias Lin: It is important that you pass the FLAG_UPDATE_CURRENT flag with the expectation that additional data is transmitted and actually received with the broadcast.
