Please help.
You should uninstall the HAXM and reinstall it, make sure to allocate at least 2 GB of ram to it. and when you create your emulated device give it less then you gave to the HAXM i'd say 1 GB that should speed things up . but i wold suggest you more RAM 8 GB is low. My system is using 10 GB with Google Chrome, Android Studio and emulator open. When going to a new version you should also go to File > Invalidate Caches / Restart
I had the same problem with Android studio 3.0.1, tried to follow above but didn't work.
Strangely changing the Target from "Open Select Deployment Target Dialog" to "Emulator" in "Run/Debug Configurations" fixed this problem.
Test app has been installed. After successful installation, I have reverted back the Target still works.
May be your h/w acceleration is disabled. You should try enabling h/w acceleration through BIOS. This might help with slow speed.
Make sure you have a stabile internet connection with your preferred Proxy settings. My corporate proxy settings caused this error.
Wiping data for your virtual device might also do the trick (Wipe data from Actions dropdown).
