Problem when trying to run uiautomatorviewer

I want to run Android studio Uiautomatorviewer on Manjaro Linux but it says there is no SWT found.
I want to install SWT using:

yay -S swt

but it says there is no Cairo found.
I installed the cairo using:

yay -S cairo

but when I want to install the SWT, again it says there is no cairo.
I want to install Cairo from the source but then it says there is no lzo2 and libpng found.
I installed the two libs but again Cairo can’t build because of these two libs.

how can I fix this problem?
Thank you for your help!


I checked cairo with pacman.

[nls@lap ~]$ sudo pacman -S cairo
[sudo] password for nls:

I found swt, the open source widget toolkit for java, found in the AUR with pamac

yes that is there, but pamac couldn’t build it:

Check you have prerequisites installed:

If you bothered to investigate why it fails - by reading the error message - applying some developer logic …

Then you find this

Which indicates an unsupported java source version

Then you should check which jdk is required, install it and use archlinux-java to set the active jdk.

Hey, I had the following problem with UIAutomatorViewer:

Exception in thread "main" java.lang.UnsatisfiedLinkError: no swt-pi-gtk-3550 or swt-pi-gtk in swt.library.path, java.library.path or the jar file

And solve it you simply need to install these packages (they are not in AUR):

sudo pacman -S gtk2 gtk-engine-murrine

Hope this helps!
