A react-native module to get the device rotation/attitude (roll, pitch, azimuth)

Package Exports

  • react-native-device-rotation

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-native-device-rotation) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

react-native-device-rotation

Get updates about a phones attitude in three axis. Values are in degrees and are roll, pitch and azimuth. Works for android and iOS. From my testing the differences are: pitch degrees are flipped for android and iOS, north (azimuth = 0) is the top of the phone in android and the right og the phone in iOS.

TODOS:

  • it's an early version of the package, so theres room for improvements
  • make sure values are the same on ios and android
  • method to check availability of the sensors

Getting started

yarn add react-native-device-rotation

Mostly automatic installation

react-native link react-native-device-rotation

Manual installation

iOS

  1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
  2. Go to node_modules ➜ react-native-device-rotation and add RNDeviceRotation.xcodeproj
  3. In XCode, in the project navigator, select your project. Add libRNDeviceRotation.a to your project's Build Phases ➜ Link Binary With Libraries
  4. Run your project (Cmd+R)<

Android

  1. Open up android/app/src/main/java/[...]/MainActivity.java
    • Add import org.muxe.devicerotation.RNDeviceRotationPackage; to the imports at the top of the file
    • Add new RNDeviceRotationPackage() to the list returned by the getPackages() method
  2. Append the following lines to android/settings.gradle: include ':react-native-device-rotation' project(':react-native-device-rotation').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-device-rotation/android')
  3. Insert the following lines inside the dependencies block in android/app/build.gradle: compile project(':react-native-device-rotation')

Usage

import RNDeviceRotation from 'react-native-device-rotation';

componentDidMount() {
        // only does stuff in iOS currently
        RNDeviceRotation.setUpdateInterval(0.2)

        const orientationEvent = new NativeEventEmitter(RNDeviceRotation)
        this.subscription = orientationEvent.addListener('DeviceRotation', event => {
            log('DeviceRotation', event)
            this.setState({
                roll: event.roll,
                pitch: event.pitch,
                azimuth: event.azimuth,
            })
        })
        RNDeviceRotation.start()
    }

    componentWillUnmount() {
        if (this.subscription) {
            this.subscription.remove()
        }
        RNDeviceRotation.stop()
    }
