React Native Background Task

Abstract

1. Introduction

Periodic background tasks for React Native apps, cross-platform (iOS and Android), which run even when the app is closed.

This library allows the scheduling of a single periodic task, which executes when the app is in the background or closed, no more frequently than every 15 minutes. Network, AsyncStorage etc can be used (anything except UI), so perfect for things like a background data sync for offline support.

which uses the iOS-specific Background Fetch technique.

2. Objective

Periodic background tasks for React Native apps, cross-platform (iOS and Android), which run even when the app is closed.

This project demonstrates how Java, React Native, Android can be applied to a real-world Mobile App Development problem.
