Compile and deploy React Native Android app of Release version to device.
Disclaimer: The instructions are the collective efforts from a few places online.
Nothing here is my original. But I want to put them together in one place to save people from spending the same time as I did.
First off, bundle.
==================
1. cd to the project directory
2. Start the react-native packager if not started
3. Download the bundle to the asset folder:
curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle"
