This article will guide you to build your Android apps with Mobile source code

Prerequisites

Mobile Devices

Development Environment

We recommend to use macOS system as a development environment because:

• Able to develop cross platform Mobile application (Android, iOS).
• We got tons of utilities scripts that were mainly written in Bash Script, which tested and worked compatibly only with Unix environment.

We assume that you have experiences in React Native project and how to build React Native mobile apps. Please following this Environment Setup guide to set up the development environment for React Native (RN) project

• Node version >= 16.14
• Yarn version = 1.21.0

Project structure

Folder packages: contains all main RN/Javascript code

Folder app: Contains entrypoint for each module section from folder `packages`. Do not change anything here, we got the script to handle these generated code

Folder android: Contains Java/Kotlin native code - mostly handle native things for Android app
