# I've found that the "Migrate to AndroidX" converter in Android Studio doesn't work very
# well, so I wrote my own script to do the simple job of converting package names.
#
# You can download a CSV of package names here: https://developer.android.com/topic/libraries/support-library/downloads/androidx-class-mapping.csv
#
# It'll run faster on a clean build because then there are fewer files to scan over.
#
# Uses `gsed` because I'm on a Mac. Can easily replace with `sed` if you don't have `gsed`.

Install and Create Emulators using AVDMANAGER and SDKMANAGER

TL;DR

For an emulator that mimics a Pixel 5 Device with Google APIs and ARM architecture (for an M1/M2 Macbook):

1. List All System Images Available for Download: sdkmanager --list | grep system-images

2. Download Image: sdkmanager --install "system-images;android-30;google_atd;arm64-v8a"
