Came here first then continued down the results and came across an elegant answer. (Vincent Tsao on 12 May 11)

private static final boolean isA = UUID.randomUUID().getLeastSignificantBits() % 2 == 0; 

public void onCreate(Bundle savedInstanceState){ 
   super.onCreate(savedInstanceState); 

   if(isA){ 
       setContentView(R.layout.mainA); 
       MyApp.getInstance().tracker().trackPageView("/AUser"); 
   }else{ 
       setContentView(R.layout.mainB); 
       MyApp.getInstance().tracker().trackPageView("/BUser"); 
   } 
   ... 
}

My only thought is to save the choice so they return to the same layout each time.
