title: "java.exe" exited with code 2 Xamarin.Android project
body: <p>so I have my Xamarin.Android project which contains several libraries. When I try to build I receive an error which says "java.exe" exited with code 2. </p>
  
  <p>After some hours of google research I found out that I could enable Multidex.
  According to the blog entry of Jon Doublas I did the steps mentioned. 
  <a href="http://www.jon-douglas.com/2016/09/05/xamarin-android-multidex/" rel="noreferrer">http://www.jon-douglas.com/2016/09/05/xamarin-android-multidex/</a></p>
  
  <p>According to the blog entry Android API Level > 21 handles Multidex itself. 
  Well my experience is that it does not. I am building on API Level 25 and get the same error again and again with the same information. 
  The steps in the article do not help. It seems like Xamarin.Android does not support Multidex. </p>
  
  <p>It seems like you have to handle Multidex by yourself but I haven't found any solution which is working. Dos anybody found a solution which works? </p>
  
  <p>I am using Xamarin 4.6 and Visual studio 2017.</p>
