Visual Studio 2015 for android 中的 Xamarin 设计器异常

Question

您好！ 我更改并保存文件 *.axml，但设计器因错误而崩溃。 我重新安装了 Visual Studio、SDK Ansroid、Xamarin、Windows 10，但无法正常工作。我的系统绝对干净。

我的系统： 视窗 10, Visual Studio 2015 专业版 (Update3), Xamarin 版本 4.2.0.680， Android SDK 工具版本 25.2.2， SDK 平台 Android 6.0、5.0.1、4.42、 JDK 1.8

请帮帮我。

这可能是需要 JDK 8 64 位的最新 Xamarin Android Designer 的问题。请在此处查看发行说明： https://developer.xamarin.com/releases/android/xamarin.android_7/xamarin.android_7.0/

相关文字：

注意：Xamarin.Android 7.0 需要 JDK 1.8 才能使用 Android Nougat (API 24) API。如果针对较早的 Android API 级别，您可以继续使用较早版本的 JDK：

JDK 1.8 - API 24+

JDK 1.7 - 最高 API 23

JDK 1.6 - 最高 API 20

另外需要64位版本的JDK才能使用custom controls in the Android designer.

最简单的选择是安装 JDK 1.8 的 64 位版本，因为它向后兼容所有以前的 API 级别并支持新的 Android 设计器功能。

（不幸的是，JDK 1.8 的一个复杂问题是与 Android SDK 中包含的过时版本的 Proguard 不兼容。目前，当尝试使用 Proguard 时，这将导致错误“Unsupported class version number [52.0]”或 Xamarin.Android 中的 Multidex 功能。请参阅44187。）
