Answer 1

For those that nothing works in this page or in the whole internet(just like me), try to uninstall your android studio then reinstall. (You don't have to uninstall sdks, avd. Settings can also stay the same. Just the main program needs uninstall) When you reinstall Android Studio, change the version to 27 as in the image. That is it, hope it works for you too
