[Linux only] Download and Install latest Android Studio anytime

install-latest-android-studio.sh

#!/bin/bash

# For most (if not all) Linux distros, there is no official repository package available to install Android Studio
# and still get regular updates. I made the below bash script that'll automatically scrape their download site for
# the download link of the latest version and can also optionally install it.
# As a forewarning, the method used to scrape the download link (sed and grep) may not always work, in which case,
# the script will notify it and exit without making any changes.
