Android 4.4 is the first version of android that supports remote debugging. GapDebug makes use of this capability.
If you’re device is not at the Android 4.4 level consider giving genymotion (https://www.genymotion.com/) android emulator a try. Its a much better experience than the Google Android emulator. I use it frequently to test for devices/os versions that I don’t have a device for, e.g., lollipop.
