android - uiautomatorviewer 不适用于最新的 MacOS

Question

我正在尝试在 MacOS 10.15 上使用 uiautomatorviewer。我收到以下错误。

我在 MacOS 10.13 上测试了 uiautomatorviewer。它工作得很好。

这是错误信息:

Unexpected error while obtaining UI hierarchy java.lang.reflect.InvocationTargetException  on latest Mac OS

这是日志的详细信息

Unhandled event loop exception during blocked modal context.

此问题发生在 SDK 版本中。我通过执行以下操作解决了我的问题-

将您的 Java 版本降级为“1.8.0_231”，您可以在此处获取:https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html

在你的 bash_profile 中设置环境。这样做

go to MAC DISK and find ".bash_profile"Open,edit and set the path

例子:

export ANDROID_HOME=~/Library/Android/sdk
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_231.jdk/Contents/Home

export PATH=$PATH:$JAVA_HOME/bin
export PATH=$PATH:$JAVA_HOME/lib
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/build-tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/tools/lib/x86_64

退出终端并重新打开输入“uiautomatorviewer”并回车...

就是这样。
