title: Passing values to an activity which I don't want to display
body: <p>I've got an activity (say activity 1) which sends a bunch of extras to another activity (activity 2). I'd like those extras to be sent to activity 2, but I don't want that activity to display at all.</p>
  
  <p>I'd like to send the intent to activity 2, and go straight into activity 3.</p>
  
  <p>The reason for this is:</p>
  
  <blockquote>
    <p>Activity 1: User chooses some options from the UI</p>
    
    <p>--> Activity 2 is sent some of the chosen parameters</p>
    
    <p>--> A service is started which uses the parameters from activity 2</p>
    
    <p>Activity 3 is displayed, which is the next UI for the user.</p>
  </blockquote>
  
  <p>One approach was to just start activity 2, and have activity 2 start activity 3. This doesn't work for me though, because even without a content view, activity 2 still tries to display momentarily. Also, if the back button is used from activity 3, then activity 2 shows up. I'd like to never show activity 2.  Should activity 2 be a service?</p>
