Uiautomatorviewer SWT异常 [英] Uiautomatorviewer SWT exception

问题描述

因为StackExchange建议我不要在

Since StackExchange advised me to not ask for help or clarification on a previously existing post, I am making a new thread.

在Windows 10x64上，我下载了 Eclipse SWT (在下载"页面的倒数第二部分)中，将我的ANDROID_SWT环境变量设置为<download location>\swt.jar，并尝试再次从cmd运行uiautomatorviewer，仅收到与以下情况相同的错误消息:我试图使用与Eclipse捆绑在一起的SWT:

On Windows 10x64 I downloaded the Eclipse SWT (in second-to-last section of Downloads page), set my ANDROID_SWT environment variable to <download location>\swt.jar, and have attempted to run uiautomatorviewer from cmd again, only to receive the same error message as when I tried to use the SWT bundled with eclipse:

Error: A JNI error has occurred, please check your installation and try again

    ... 7 more

是否还有其他人遇到此错误，如果是，根本原因是什么?

Has anyone else encountered this error, and if so, what was the root cause?

提前感谢您的时间和帮助！

Thanks in advance for your time and help!

推荐答案

严格按照这些说明.我尝试下载Eclipse SWT来解决我遇到的其他问题时犯了一个错误.在CLASSPATH和ANDROID_SWT环境变量中设置此不同的SWT版本会导致此异常.

Precisely follow these instructions. I made the mistake of trying to download the Eclipse SWT in order to troubleshoot other issues I was having; setting this different SWT version in the CLASSPATH and ANDROID_SWT environment variables caused this exception.
