Cannot run uiautomatorviewer.bat from Android sdk tools
我正在尝试 运行 uiautomatorviewer.bat 来自 Android sdk 工具。
它在我以前的系统上运行良好，现在不行了。
在我以前通过更改 *.bat 文件
的最后一行来编辑 *.bat 文件之前，使其成为 运行

现在，当我尝试 运行 uiautomatorviewer.bat 时，我看到了这个错误：
C:\Android\Sdk\tools\bin>uiautomatorviewer
-Djava.ext.dirs=..\lib\x86_64;..\lib is not supported. Use -classpath instead.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
我一直在寻找如何使用 -classpath 的不同解决方案，但 none 个对我有所帮助
不是.bat文件的问题。
我遇到了同样的问题，因为我使用的是 Java 10。
当我将 Java 10 降级到 Java 8 时，它又开始工作了。
请记住按照此处的说明设置变量 http://www.automationtestinghub.com/setup-java-environment-variables/。
我现在使用 uiautomatorviewer 的 Java 版本是 jdk-8u171-windows-x64.exe.
降级到Java8，可在C:\Program Files\Java\jre1.8.0_201
添加环境变量 Java_Home.
在 C:\Users<用户名>\AppData\Local\Android\tools\bin
中打开新命令 window
输入 uiautomatorviewer.bat
它会起作用。
的jdk8安装
它自带JRE，你需要在JAVA_HOME路径下安装JRE，无论你使用哪个JDK版本。
只要下载jdk8就可以运行uiautomatorviewer.bat
