title: Imported type defined multiple times on Xamarin Android
body: <p>I'm getting the following error in my Xamarin.Android project: </p>
  
  <blockquote>
    <p>The imported type Android.Support.v4.view.ViewPager is defined multiple times </p>
  </blockquote>
  
  <p>I found <a href="https://stackoverflow.com/questions/23496549/imported-type-defined-multiple-times-on-xamarin-android">this</a> solution, but doesn not work. In fact I need to use the Google Play Store binding library and it uses both support v4 and v7. If I try to remove the v4 I get an error like this:</p>
  
  <blockquote>
    <p>Unable to uninstall 'Xamarin.Android.Support.v4 20.0.0.4' because 'Xamarin.GooglePlayServices 19.0.0.1' depends on it.</p>
