title: Xposed: how to block a method call
body: <p>I'm using Xposed to do some method hooking (for now, just for learning).
  I've manged to hook the method SendTextMessage (android.telephony.SmsManager), 
  i can do some things before the call and after the call of the method, so my question is, can i do something in the before that will cause the original method not be called?</p>
  
  <p>Thanks,</p>
