title: Using If and else to change to change layout file @ runtime
body: <p>I am currently working on a project that i am trying to add an icon making competition and the winner will receive a special app plugin that only the contest winner will get and i would like my app to check if the package(special app plugin) exists on the users device and if it does i would like the app to display an alternate display on run-time.Would i use "if"
  and "else" statements to achieve this and if so how would i go about this and Thanks in advanced.</p>
  
  <p>Note:I have successfully made the app load a different layout depending on the android version so i have a little bit of an idea but need some help. </p>
