没有导航编辑器 - Android Studio Canary 15和16

Question

我在绞尽脑汁.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,我在创建xml文件时得到的是以下消息,编辑器从未显示;

我已经卸载并重新安装了我安装的Android Studio和Android Studio Canary 15(驻留在C:\ Program Files\Android\Android Studio和C:\ Program Files\Android\Android Studio Canary以及所有相关组件中) C:\ Users\[用户名]\.AndroidStudio文件夹.

任何想法为什么这不起作用？

编辑:好的所以现在有一条错误消息,当我禁用Android支持插件时,我收到一些错误消息,告诉我重新启用插件!

编辑2:我更新到金丝雀16,问题仍然存在.

编辑3:我的导航图'main_graph.xml'如下;

<?xml version="1.0" encoding="utf-8"?>

<navigation xmlns:android="http://schemas.android.com/apk/res/android">
</navigation>

Answer 1

你有测试帮助依赖,尝试删除它.它和导航编辑器存在问题

androidTestImplementation "android.arch.navigation:navigation-testing:$nav_version"

然后点击重启并清理缓存.
