Question

Answer 1

React Native is open source, so you can find the code for the CLI on Github: https://github.com/facebook/react-native/blob/master/local-cli/runAndroid/runAndroid.js

If you prefer to check it locally, you can find the code in your RN project under node_modules/react-native/ where the run-android code is in local-cli/runAndroid/runAndroid.js.
