Note

Example only works on a real device

Breaking change for permission since V1.5.0, see Android Permission

How it looks

Install

Using npm:

npm install react-native-system-setting --save

or using yarn:

yarn add react-native-system-setting

Link

If using react-native < 0.60, run react-native link to link this library.

iOS

todo: confirm this

Add pod 'RCTSystemSetting', :path => '../node_modules/react-native-system-setting' in Podfile for Cocoapods.

If linking with react-native link did not work, you can do it manually.

Android

If linking with react-native link did not work, you can do it manually by following these steps:

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')
}

android/app/src/main/java/..packageName../MainApplication.java

At the top of the file, import react-native-system-setting:

import com.ninty.system.setting.SystemSettingPackage;

Add the SystemSettingPackage class to your list of exported packages.

class MainApplication extends Application implements ReactApplication {
    // ...
    @Override
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>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)       

setVolume can do more, more detail

Brightness

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

// change the brightness & check permission
SystemSetting.setBrightnessForce(0.5).then((success) => {
    !success && Alert.alert('Permission Deny', 'You have no permission changing settings', [
        {'text': 'Ok', style: 'cancel'},
        {'text': 'Open Setting', onPress: () => SystemSetting.grantWriteSettingPermission()}
    ])
});

// 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
})

// change app's brightness without any permission.
SystemSetting.setAppBrightness(0.5);
SystemSetting.getAppBrightness().then((brightness) => {
    console.log('Current app brightness is ' + brightness);
})

setBrightness() & saveBrightness() need permission for Android

Wi-Fi

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

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

isWifiEnabled() need permission for Android

switchWifi() is disabled by default for iOS since V1.7.0, enable it

Location

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

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

switchLocation() is disabled by default for iOS since V1.7.0, enable it

Bluetooth

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

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

isBluetoothEnabled() need permission for Android

All bluetooth-function are disabled by default for iOS since V1.7.0, enable it

Airplane mode

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

SystemSetting.switchAirplane(() => {
    console.log('switch airplane successfully');
})

isAirplaneEnabled() will always return true for iOS if your device has no SIM card, see detail

switchAirplane() is disabled by default for iOS since V1.7.0, enable it

App System Settings

// open app setting page
SystemSetting.openAppSystemSettings()

API

API

Run example

cd example
yarn
# for iOS
react-native run-ios
# for Android
react-native run-android

iOS

To be app store friendly, APIs for iOS are disabled since V1.7.0, You can enable it in a few steps by following instructions in iOS.md

Android permission

API

Default permissions were removed in V1.5.0, see this PR You need to declare the corresponding permissions in your app's AndroidManifest.xml. See example AndroidManifest.xml

android/app/src/main/AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="YourPackageName"
          android:versionCode="1"
          android:versionName="1.0">

    <!-- setBrightness() & setScreenMode() & saveBrightness() -->
    <uses-permission android:name="android.permission.WRITE_SETTINGS"/>

    <!-- isWifiEnabled() -->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

    <!-- isBluetoothEnabled() -->
    <uses-permission android:name="android.permission.BLUETOOTH"/>

    <!-- * switchWifiSilence() -->
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>

    <!-- * switchBluetoothSilence() -->
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

    <!-- ... -->

</manifest>

There are some different APIs that end with silence. They can do the job programmatically without direct user consent. These APIs may be useful when you develop a system management app. You should call switchWifi() & switchBluetooth() to get a better user experience

Do Not Disturb

setVolume() may cause a crash: Not allowed to change Do Not Disturb state. See detail.

Runtime permission for Android 6+

Change brightness and screen mode need android.permission.WRITE_SETTINGS which user can disable it in Android settings. When you call setScreenMode(), setBrightness() or setBrightnessForce() , it will return false if the app has no permission, and you can call SystemSetting.grantWriteSettingPermission() to guide user to app setting page. There is also a SystemSetting.checkWriteSettingsPermissions() API to check if the app has WRITE_SETTINGS permission.

If you just want to change app's brightness, you can call setAppBrightness(val), and it doesn't require any permission. see API
