Block outgoing SMS by contentObserver

Question

I want to block SMS by contentObserver. For that I want to get the phone number of the SMS first. What do I do to get the number? This is the code that I have,

Answer 1

I have done a lot of tests and I found this to be impossible. That's because when the messaging application inserts a new record in the SMS content provider, it is already trying to send the SMS. So, even if you detect the SMS in the content://sms/outbox URI, it will be too late to stop it. In fact, there's no way to stop it... it all depends on the SMS application, which you can't interrupt.

Answer 2

Nope, you cant. Observer will comeinto affect after dataset has been modified, by that time sms will already be on the way for delivery. Infact by any means you cant block outgoing sms.
