无法从Android SDK工具运行uiautomatorviewer.bat

Question

我正在尝试从Android SDK工具运行uiautomatorviewer.bat。

它在我以前的系统上工作正常，现在不是。

通过更改*.bat文件中的最后一行来编辑*.bat文件之前，要使它运行

    echo SWT folder '%swt_path%' does not exist.
    echo Please set ANDROID_SWT to point to the folder containing swt.jar for your platform.
    exit /B

set javaextdirs=%swt_path%;%frameworkdir%
call "%java_exe%" "-Djava.ext.dirs=%javaextdirs%" "-Dcom.android.uiautomator.bindir=C:Androidsdktools" -jar %jarpath% %*

现在，当我尝试运行uiautomatorviewer.bat时，我会看到此错误：

C:AndroidSdktoolsbin>uiautomatorviewer
-Djava.ext.dirs=..libx86_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.

我正在寻找不同的解决方案如何使用-ClassPath，但它们都没有帮助

Answer 1

不是.bat文件问题。

我遇到了同样的问题，因为我正在使用Java10。

当我将Java 10降级到Java 8时，它再次开始工作。

记住在此处解释时设置变量，http://www.automationtestinghub.com/setup-java-environment-variables/。

现在，我的Java版本正在使用UiautomatorViewer，是JDK-8U171-Windows-x64.exe。

Answer 2

降级为java8，可在 c： program文件 java jre1.8.0_201
中使用。添加环境变量Java_home。

c： users＆lt; username＆gt; appdata local android android tools bin bin

打开新的CMD窗口输入uiautomatorviewer.bat

它将起作用。

Answer 3

JAVA下载页面的JDK8安装

它带有JRE，无论您使用哪种JDK版本，您都需要在JAVA_HOME路径上使用JRE。

只需下载JDK8即可运行uiautomatorviewer.bat
