Starting with Xamarin.Forms 1.5.1 pre-2

Hello,

I started to check the new pre release from Xamarin with Material Design support, and I get this
java.lang.RuntimeException: Unable to find application Mono.Android.Platform.ApiLevel_23 or Xamarin.Android.Platform

I found a couple of topics about how to solve it on previous versions. Like change True to False on the csproj the property AndroidUseLatestPlatformSdk.
Hope someone can help me with that.

Regards!
