这可以是最新的Android Xamarin需要设计师在JDK 8的64位的问题。请参阅发布说明： https://developer.xamarin.com/releases/android/xamarin.android_7/xamarin.android_7.0/

相关的文字：

注：Xamarin.Android 7.0要求JDK 1.8使用Android牛轧糖（API 24）的API。您可以继续如果定位早期的Android API级别使用早期版本的JDK：

JDK 1.8 - 高达24+ API

JDK 1.7 - 高达23 API

JDK 1.6 - 高达20 API

此外，64位版本的JDK需要使用custom controls in the Android designer.

最简单的选择是安装64位版本的JDK 1.8，因为它是b与以前的所有API级别兼容并支持新的Android设计器功能。

（JDK 1.8的一个不幸并发症是与Android SDK中包含的过时版本的Proguard不兼容，当尝试使用该版本时会导致错误“Unsupported class version number [52.0]” Xamarin.Android中的Proguard或Multidex功能见44187。）
