[안드로이드 / android] UiAutomatorviewer Window에서 실행되지 않는 문제

Recently one of my students was getting this error – I thought I would put it here in case anyone else could be benefited:

Issue:

On clicking uiautomatorviewerbat file, i am getting this error in cmd

-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.
Press any key to continue . . .

Solution:

This issue is caused by incompatible Java version. If you are getting this issue, please uninstall JDK 9 and install JDK 8. This will fix your issue.
