title: Can't setup Android SDK on Visual Studio 2015
body: <p>I just installed my VS2015 enterprise and  I want to try "cross platform" or "Android blank App" project, but in both , I got a message box with this error </p>
  
  <blockquote>
    <p>Value cannot be null<br>
    Parameter name:path1</p>
  </blockquote>
  
  <p>When I try to run Tools/Android /Android SDK Manager I got a Visual Studio error:</p>
  
  <blockquote>
    <p>Error: Command did not execute uccessfully due to an unexpected exeption.Please check the output window for aditional information</p>
  </blockquote>
  
  <p>In the error window I got</p>

  <p>It looks like it can't download something, I guess there is no Android SDK installed on my PC.</p>
  
  <p>I've tried disabling my firewall but it's the same, any idea?</p>
