rnpm link react-native-device-brightness

Hey, bro! react-native-device-brightness wasn't support older version of React Native yet.

Manually link

iOS (without Cocoa Pods)

In XCode, in the project navigator:

• Right click Libraries
• Add Files to [your project's name]
• Go to node_modules/react-native-device-brightness
• Add the .xcodeproj file

In XCode, in the project navigator, select your project.

• Add the libRNDeviceInfo.a from the deviceinfo project to your project's Build Phases ➜ Link Binary With Libraries
• Click .xcodeproj file you added before in the project navigator and go the Build Settings tab. Make sure All is toggled on (instead of Basic).
• Look for Header Search Paths and make sure it contains both $(SRCROOT)/../react-native/React and $(SRCROOT)/../../React
• Mark both as recursive (should be OK by default).

Run your project (Cmd+R)

Android

• in android/app/build.gradle:

dependencies {
    ...
    compile "com.facebook.react:react-native:+"  // From node_modules
  compile project(':react-native-device-brightness')
}

• in android/settings.gradle:

...
include ':app'
include ':react-native-device-brightness'
project(':react-native-device-brightness').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-device-brightness/android')

With React Native 0.29+

• in MainApplication.java:

+ import com.learnium.RNDeviceInfo.RNDeviceInfo;
public class MainApplication extends Application implements ReactApplication {     //......
@Override     protected List<ReactPackage> getPackages() {       return Arrays.<ReactPackage>asList( 
        new RNDeviceInfo(),
 
          new MainReactPackage()       );     }

......   }

With older versions of React Native:

• in MainActivity.java:

+ import com.learnium.RNDeviceInfo.RNDeviceInfo;
public class MainActivity extends ReactActivity {     ......
@Override     protected List<ReactPackage> getPackages() {       return Arrays.<ReactPackage>asList( 
      new RNDeviceInfo(),
 
        new MainReactPackage()       );     }   }

Usage

Important: Brightness Level only accept value 0 to 1.

• Adjusting screen brightness will make iOS's Auto-Brightness function do nothing.
• Adjusting screen brightness in Android only works in App and will reset to system setting exiting App.

// ES5
var DeviceBrightness = require('react-native-device-brightness');
// or ES6
// import DeviceBrightness from 'react-native-device-brightness';
// It will throw a exception when value less than 0 or more than 1. DeviceBrightness.setBrightnessLevel(luminous); DeviceBrightness.getBrightnessLevel()     .then(function (luminous) {         // Get current brightness level         // 0 ~ 1         console.log(luminous);     }); // Android only DeviceBrightness.getSystemBrightnessLevel()     .then(function (luminous) {         // Get current brightness level         // 0 ~ 1         console.log(luminous);     });
