With the new theming in AppCompat, a lot of assets are tinted automatically for you via theme attributes. That has often led me to wonder "where the hell did this color come from?" You can replace your normal theme with this debug theme to help figure out the source of that color.
<!-- You can change the parent around to whatever you normally use -->
<style name="DebugColors" parent="Theme.AppCompat">
<!-- System colors -->
<item name="android:windowBackground">@color/__debugWindowBackground</item>
<item name="android:colorPressedHighlight">#FF4400</item>
<item name="android:colorLongPressedHighlight">#FF0044</item>
<item name="android:colorFocusedHighlight">#44FF00</item>
<item name="android:colorActivatedHighlight">#00FF44</item>

Simple AndroidX Migration Script
#!/usr/bin/env bash
# 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`.
