uiautomatorviewer文件的位置“获取UI层次结构时出错”

Question

如果我可以在此处保存一些内容，我会在uiautomatorviewer中使用最左和最右按钮进行游戏

它似乎可以在此处指定文件，但现在它声明缺少文件

在stacktrace中，我看到

$ uiautomatorviewer

One of the two will be used. Which one is undefined.

问题是： 如何摆脱错误的 allow.uix 文件？ uiautomatorviewer现在不再可用，我要开始使用这种文件。

顺便说一句，这无济于事

sudo adb kill-server
sudo adb start-server

经过大量调查（包括以下源代码）： https://android.googlesource.com/platform/frameworks/testing/+/aecdc4a/uiautomator/utils/uiautomatorviewer/src/com/android/uiautomator）

一个简单的重启使其又可以工作！
