System info

Note

Example only work in the real device

Change Log

Look like

I really want to show the .gif, while it has no difference with .jpg for some system limit.

I strongly recommend you to run the example in real device to see how it works.

Install

Run npm i -S react-native-system-setting

iOS

Run react-native link to link this library.

Android

Run react-native link to link this library.

That's all.

If link does not work, you can do it manually. Just follow this way:

android/settings.gradle

include ':react-native-system-setting'
project(':react-native-system-setting').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-system-setting/android')

android/app/build.gradle

dependencies {
   ...
   compile project(':react-native-system-setting')
}

MainApplication.java

On top, where imports are:

import com.ninty.system.setting.SystemSettingPackage;

Add the SystemSettingPackage class to your list of exported packages.

@Override
protected List<ReactPackage> getPackages() {
    return Arrays.asList(
            new MainReactPackage(),
            new SystemSettingPackage()
    );
}

Usage

Common import

import SystemSetting from 'react-native-system-setting'

volume

//get the current volume
SystemSetting.getVolume().then((volume)=>{
    console.log('Current volume is ' + volume);
});

// change the volume
SystemSetting.setVolume(0.5);

// listen the volume changing if you need
const volumeListener = SystemSetting.addVolumeListener((data) => {
    const volume = data.value;
    console.log(volume);
});

//remove listener when you need it no more
SystemSetting.removeVolumeListener(volumeListener)

brightness

//get the current brightness
SystemSetting.getBrightness().then((brightness)=>{
    console.log('Current brightness is ' + brightness);
});

//change the brightness
SystemSetting.setBrightnessForce(0.5);

// save the value of  brightness and screen mode.
SystemSetting.saveBrightness();
// restore the brightness and screen mode. you can get the old brightness value.
SystemSetting.restoreBrightness().then((oldVal)=>{
    //if you need
})

Wifi

SystemSetting.isWifiEnabled().then((enable)=>{
    const state = enable ? 'On' : 'Off';
    console.log('Current wifi is ' + state);
})

SystemSetting.switchWifi(()=>{
    console.log('switch wifi successfully');
})

Location

SystemSetting.isLocationEnabled().then((enable)=>{
    const state = enable ? 'On' : 'Off';
    console.log('Current location is ' + state);
})

SystemSetting.switchLocation(()=>{
    console.log('switch location successfully');
})

Bluetooth

SystemSetting.isBluetoothEnabled().then((enable)=>{
    const state = enable ? 'On' : 'Off';
    console.log('Current bluetooth is ' + state);
})

SystemSetting.switchBluetooth(()=>{
    console.log('switch bluetooth successfully');
})

API

Run example

$ cd example/SystemSettingExample
$ npm install
// if android
$ react-native run-android
// else
$ react-native run-ios

Android permission

To simplify using, I have declared all permission in AndroidManifest.xml.

And you can delete the permission safely if it's useless for you app.

You can find the file in yourProject/node_modules/react-native-system-setting/android/src/main/AndroidManifest.xml. (Be sure that you have run npm install)

These permissions are transparent in iOS, so it's ok for iOS app.

In the end
