在运行UI AUTOMATOR时获取错误，使用java 1.8
在运行UI AUTOMATOR时获取错误，使用java 1.8
提问于 2020-07-08 01:38:53
当我在终端中打开uiatuomator时，它工作正常，但是一旦我单击uiautomator连接到模拟器，就会得到这个异常。
Android 29
终端上的异常:

这个问题发生在java版本上。我有JavaVersion1.8.262，我遇到了多个问题，甚至正确地设置了路径变量。你可以试试..。
更改java版本并正确设置path变量之后。我知道它起作用了。
将您的Java版本降级为"1.8.0_231“，您可以在这里获得：https://www.oracle.com/java/technologies/javase/javase8u211-later-archive-downloads.html
在bash_profile中设置env。要做到这一点-进入MAC磁盘并找到".bash_profile“打开，编辑并放置路径
示例：
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/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，重新打开"uiautomatorviewer“类型，然后按回车。
那就是它。
