After upgrading to the latest Ubuntu and Android Studio versions, you have to do a few simple things in order to use the Android Emulator.
When you try to start an emulator, you will be required to grant access of the current user to /dev/kvm.
You can do this task with the following steps:
- Check if you already have a permission:
grep kvm /etc/group
If you see this:
kvm:x:105:[YOUR_USER], you have a permission.
- Add your user:
sudo adduser [YOUR_USER] kvm
- And the last step - logout
That's it! Now you can use the emulator! :)
