Android studio comes with its own built in version of QEMU (because google is special). If someone installs android-studio but does not install qemu or does not already have it installed then the udev rules for kvm will be missing. Any attempt to run an AVD will be met with permission denied errors on /dev/kvm. The android-studio ebuild should borrow the udev rules from the qemu ebuild and install them into /lib/udev/rules.d/ just as if qemu had been installed. I shall leave it up to the gentoo devs as to how best to resolve any potential conflicts here :)
please add cat/pkg to the title.
