About

Most mobile apps will require some type of network calls. We use fetch to make an HTTP call to a simple REST API server.

The server can get and update tasks, and uses JSON to communicate data back and forth with React Native.

When using the Android emulator, as you mentioned, you replace localhost, I think you replace it with: 10.0.2.2 (I found this on StackOverflow, and also noticed, this is IP the reloader is reporting when I reinstall the app). Hope this helps some Android folks.
