Android Emulator doesn't work - address resolution failed for ::1

Hi all,
Yes, the topic isn't new. I did some research and fixed my initial problems but I'm stuck now and need some help/advice.

I'm new to Android Studio on Linux. I used it some years ago on Windows for a month or two - everything went smooth.
I installed android-studio package from AUR yesterday and it works, no problem. I downloaded SDK and emulator packages from Tools menu of Android Studio. I created AVD. But I can't start it.
It appears my initial problems were caused by absence of qemu. So I installed it and now things look better (but I'm not sure that I selected correct qemu option as there was 2 of them: qemu-base, qemu-desktop, qemu-full).

I have this in logs now and nothing happens. No emulator window appears, no error is shown... I don't understand where the problem is.
The address seems to be a localhost... have no idea why it isn't resolved.

But I noticed this in output of systemctl status libvirtd.service:

my_pc libvirtd[4568]: Unable to find 'dnsmasq' binary in $PATH: No such file or directory

I don't have dnsmasq installed. But do I really need it?

Re: Android Emulator doesn't work - address resolution failed for ::1

Ok, I did some more googling... and found an advice to disable IPv6 via

sysctl net.ipv6.conf.all.disable_ipv6 = 1

I tried and it works - emulator started up and worked for some time (it crashed later but I haven't discovered why).

But I wouldn't like to disable IPv6 completely... does anyone know how to try fixing it another way?

Here is my /etc/hosts:

[root@my_pc ~]# cat /etc/hosts
# Static table lookup for hostnames.
# See hosts(5) for details.
127.0.0.1       localhost
::1             localhost
127.0.0.1       my_pc.localdomain       my_pc
[root@my_pc ~]#

Re: Android Emulator doesn't work - address resolution failed for ::1

address resolution failed for ::1:44869

It looks like qemu is trying to add a special device to port 44869 on localhost .

How are you starting the VM (CLi, libvirt, other qemu gui , something else ) ?

-chardev socket,port=44869,host=::1,nowait,nodelay,ipv6,id=modem

Looks like qemu tries to add a special device to localhost in the vm.

This isn't my own VM - it is Android emulator that is part of Android Studio.
I start it with the command I wrote in the first message:

/home/user/Android/Sdk/emulator/emulator -avd Pixel_3a_API_33_x86_64

I.e. I only give the name of AVD (android virtual device) to it.

Re: Android Emulator doesn't work - address resolution failed for ::1

The output suggests like this may be caused by version conflicts between systemwide installations and user installed stuff .

Can you try installing https://aur.archlinux.org/packages/android-emulator (possibly also installing https://aur.archlinux.org/packages/android-sdk ) and see if your AVD does run with the systeminstalled emulator then ?
