title: Android app startup wizard
body: <p>I'm looking to figure out a solution for helping a user enter some configuration data during the first time it's executed.  I have a main activity that shows a list of photos in a grid.</p>
  
  <p>During the onCreate method for the main activity, if I find that a user has not configured the app before, I switch to a series of two activities.  The user fills out the required data in those two activities (think wizard-style, one after another).  Once they have entered data on the second activity, they are shown the original main activity.</p>
  
  <p>Is this a standard, or preferred way to do things?  I couldn't find an easier way to do this, or a built-in way.  </p>
  
  <p>Instead of using onCreate, is there a way to programatically choose the first activity based on whether it's the first time the app has been run or not?</p>
  
  <p>Thanks,
  Kevin</p>
