react-native-android-wake-lock

Native Module for setting a wake lock on an Android device. Utilizes both PowerManager and WifiManager.

Installation

Note: This package requires React Native >=0.60.

Install with npm/yarn.

npm install react-native-android-wake-lock --save
// or
yarn add react-native-wake-lock

Since this package requires RN 0.60 or higher, this package will be linked automatically. If you run into an issue, you can try react-native link react-native-android-wake-lock.

Usage

Make sure to request the wake lock permission. Add the following inside the project manifest (android/app/src/main/AndroidManifest.xml):

<uses-permission android:name="android.permission.WAKE_LOCK" />

This module exposes 2 possible methods for accessing the wake lock: via an interface object or a React hook. Depending on your use case, one or the other should suffice.

import React from "react";
import { WakeLockInterface, useWakeLock } from "react-native-android-wake-lock";

// the interface exposes all 3 (async) methods
const isWakeLocked = WakeLockInterface.isWakeLocked();
// these 2 aren't necessary if you're using the hook
const setWakeLock = WakeLockInterface.setWakeLock();
const releaseWakeLock = WakeLockInterface.releaseWakeLock();

// you can also use the hook to set/release a wake lock on component mount/unmount
const Component = () => {
  const [wakeLocked, setWakeLocked] = useState(isWakeLocked);

  // you can use the `isWakeLocked` method from the interface to check whether or not the wake lock is set
  useEffect(() => {
    console.log(wakeLocked);
  }, [wakeLocked]);

  useWakeLock();

  return <View />;
};

API

The interface has 3 methods:

• setWakeLock(): Promise<boolean> - sets both the WakeLock and WifiLock
• releaseWakeLock(): Promise<boolean> - releases both the WakeLock and WifiLock
• isWakeLocked(): Promise<boolean> - whether or not the wake/wifi locks are held
