How to register to change the SMS database?

Question

How can I register changes to the SMS database?

I tried:

mCursor = mActivity.getContentResolver().query(Sms.CONTENT_URI, new String[] {
           Sms.ADDRESS
   }, null, null, null);
mCursor.registerDataSetObserver(mydataSetObserver);

where mydataSetObserver is implemented as follows:

 private class MyDataSetObserver extends DataSetObserver {
       public void onChanged() {
           System.out.println ("1");
       }
       public void onInvalidated() {
            System.out.println ("2");
       }
}

But when I tried to send an SMS to the emulator, MyDataSetObserver will never be called.

Could you tell me why?

Thanks.
