Hiding API keys in local.properties

1. Add the API key to your local.properties file:

apiKey=<value>

2. Add to the root level of your app-level build.gradle file:

adb devices

adb shell screencap -p /sdcard/screen.png
adb pull -p -a /sdcard/screen.png
adb shell rm /sdcard/screen.png

For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set mydate=%%c-%%a-%%b)
For /f "tokens=1-3 delims=/:" %%a in ("%TIME%") do (set mytime=%%a-%%b-%%c)
set mytime=%mytime: =%

My notes on the video series "London vs Chicago TDD styles" by Uncle Bob And Sandro Mancuso

The git repo of the kata is here: https://github.com/sandromancuso/cleancoders_openchat/

The "starting-point" branch is where both implementations began: https://github.com/sandromancuso/cleancoders_openchat/tree/starting-point

• The 🇬🇧 "openchat-outside-in" branch captures the tomato by tomato history of the London approach.
• The 🇺🇸 "openchat-unclebob" branch captures the tomato by tomato history of the Chicago approach.

What I like about Sandro's style 👍
