title: Xamarin forces me to download Android SDK and NDK
body: <p>I have my Android SDK and NDK installed on my computer (On custom locations) . I am trying to install xamarin on my Windows environment but the installer wants to force me to install SDK and NDK . It looks like it cannot find by installations folder. Is there a solution to specify when my SDK and NDK are installed ?</p>
  
  <p>Thanks.</p>
