react-native-background-timer-android

This library provides setTimeout and setInterval implementations that keep working even if the app is running in the background or the screen is locked.

Based on react-native-background-timer but with major code changes and only works on Android.

Features

• Clear and simple API
• Can set multiple timers
• Keeps running when the screen is locked
• Each timer has its own WakeLock that remains active while it's running
• Intervals are handled entirely on the native side
• Fault-tolerant: any exception gets reported back to JS via promises
• TypeScript declarations included

Install

yarn add react-native-background-timer-android

API

Timer.setInterval(callback: ()=>void,millis: number,onError?: (error: Error)=>void): number;Timer.setTimeout(callback: ()=>void,millis: number,onError?: (error: Error)=>void): number;Timer.clearInterval(id: number): Promise<void>;Timer.clearTimeout(id: number): Promise<void>;
