content observer called twice for receiving sms

Hi I am developing an android SMS app where in I am using the ContentObserver to know the incoming message similar to this link

http://rdcworld-android.blogspot.in/2011/10/listen-sms-mms-programmatically-android.html

I need to get the count of received SMS. But, the ContentObserver onChange method is called twice and I am not able to get the proper count of received SMS. How do I resolve this

Please Help.Thanks!

It has something to do with when the SMS comes in, it'll fire, and then again when it syncs with the underlying database(s). Best solution I've found, implement a way to ignore the second call:

Long theDT = System.currentTimeMillis();
Long nextAM = Long.valueOf(1000);  //Use a 1 second minimum delay to avoid repeated calls
Long lastAM = preferences.getLong("lastAM", 0);
if ((lastAM + nextAM) < theDT1){
    SharedPreferences.Editor editor = preferences.edit();
    editor.putLong("lastAM", theDT); // value to store
    editor.commit();

    // DO WHAT YOU NEED TO DO HERE
}
