Bash script to trigger python uiautomator2 to get specific UI element on android screen and click it if it exists

android-tap-if-exists.sh

#!/usr/bin/env bash
#NOTE: requires python3 and the pip package uiautomator2
#These functions can be copied over to your own bash script
#and can be used by simply triggering tapIfExists...
