title: Android 4.4 sent SMS Stored in Inbox
body: <p>In Android 4.4, My App is not an SMS App but it need to send SMS(multiple times).
  The thing is that the Sent SMS will be stored in Default SMS App(Hangouts).
  It would spam/annoy users a lots. I would like the SMS actions are transparent/silently with End-Users. </p>
  
  <p>AFAIK, we may prevent this by setting my App at the moment I send the SMS &amp; change back later.
  But this is not really an option since end-user flow become complicated &amp; may lead to confusion. another reason is Default SMS App may lose the System Broadcast when my App was set as Default SMS App.</p>
  
  <p>Is there complete solution on this? </p>
  
  <p>Thank you for you support.</p>
