Inexpiable

If you find the logs of the IDE, that would help – Paymaster

Where is it located? – Inexpiable

In linux? /var/log maybe? Or #19785377 – Paymaster

SOLVED By doing chmod 777 emulator/ -R – Inexpiable

Answer 1

Changed permissions in the /home/folder/Android/Sdk/emulator/ folder

chmod 777 -R /home/folder/Android/Sdk/emulator/

Inexpiable

Permissioned denied to which user? 777 seems excessive – Paymaster

From android studios all users even root could not access most of the files in the Sdk folder. Instead of 777 which level is best, 555(r-x)? – Inexpiable

Ubuntu 18 'sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils' – Stutzman

The only items you need to change are chmod 775 ~/Android/Sdk/emulator/emulator* ~/Android/Sdk/emulator/qemu/linux-x86_64/qemu-system-* If you try running the emulator from the command line ~/Android/Sdk/emulator -avd (your avd name) you can easily see any errors (use -list-avds to find your avd name). Seems strange that the emulator files are not executable by default? – Alcaic

Answer 2

I also had this problem, and was able to fix it by using:

sudo chmod 777 /dev/kvm

Answer 3

In my case the error was because the user has not enough permission to /dev/kvm. So the solution is giving permission,i.e.,

chmod 777 /dev/kvm

Answer 4

You need to be part of the kvm group

Try this:

sudo adduser $USER kvm

Then relaunch android studio or unlog / relog user

Illogic
