title: android: where is the android.provider.Telephony.SMS_RECEIVED?
body: <p>I'm writing an App that needs to receive sms, everyone use "android.provider.Telephony.SMS_RECEIVED_ACTION" intent action in their code, but it looks like API level 17 doesn't support it anymore! 
  where it is now? I also didn't find SMS_RECEIVED_ACTION in "android.telephony" class!
  please someone tell me, I'm totally confused. should I use older APIs?</p>
