Hello, I made a simple instruction on how to fix some Android's UIAutomatorViewer errors which I have encountered on my machine. Here it is:
-Djava.ext.dirs=/home/user/Android/Sdk/tools/lib/x86_64:/home/user/Android/Sdk/tools/lib is not supported. Use -classpath instead.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
This error happens if your machine doesn't have Java 8 version set as system default. UIAutomatorViewer sadly works only with Java 8. To fix this problem install Java 8 and set it as default version.
For Arch Linux:
sudo pacman -S jdk8-openjdk
sudo archlinux-java set java-8-openjdk
Problem solved 🚀

You need to install gtk2 and gtk-engine-murrine dependencies.
For Arch Linux:
sudo pacman -S gtk2 gtk-engine-murrine
