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 LibrariesAdd Files to [your project's name]
  2. Go to node_modulesreact-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 PhasesLink 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()
	}
