[Mobile] Android Setup

This is a companion discussion topic for the original entry at https://docs.katalon.com/katalon-studio/tutorials/mobile-android-setup.html

How to open the Emulator (Virtual Mobile Device)
I have installed SDK, Appium Desktop, JDK and Nodejs even though the virtual device is not listed in list of adb devices.
Katalon Version 8.0.5
Appium Version 1.16.1
JDK - 1.8

I am facing issue that whenever we start running script for mobile app it takes too much time to install app first & then open so how can we reduce that time?
