没有导航编辑器 - Android Studio Canary 15 和 16
No Navigation Editor - Android Studio Canary 15 and 16
我正在为此绞尽脑汁。我正在尝试重构我的应用程序以使用 Android Studio Canary 15 中的新导航架构组件，创建 xml 文件时我得到的只是以下消息，编辑器从未出现；
我已经卸载并重新安装了 Android Studio 和 Android Studio Canary 15（位于 C:\Program Files\Android\Android Studio 和 C:\在 C:\Users\[用户名]\.AndroidStudio 文件夹中编程 Files\Android\Android Studio Canary 和所有相关组件。
知道为什么这不起作用吗？
编辑：好的，现在有一条错误消息，当我禁用 Android 支持 插件时，我收到更多错误消息告诉我重新启用插件！
编辑 2：我更新到 Canary 16，问题仍然存在。
