Handling media-routes/sensors/events during a audio/video chat on React Native


The purpose of this module is to handle actions/events during a phone call (audio/video) on react-native, ex:

  • Manage devices events like wired-headset plugged-in state, proximity sensors and expose functionalities to javascript.
  • Automatically route audio to proper devices based on events and platform API.
  • Toggle speaker or microphone on/off, toggle flashlight on/off
  • Play ringtone/ringback/dtmftone

Basically, it is a telecommunication module which handles most of the requirements when making/receiving/talking with a call.

This module is designed to work with react-native-webrtc

TODO / Contribution Wanted:

  • Make operations run on the main thread. ( iOS/Android )
  • Fix iOS audio shared instance singleton conflict with internal webrtc.
  • Detect hardware button press event and react to it.
    ex: press bluetooth button, send an event to JS to answer/hangup.
    ex: press power button to mute incoming ringtone.
  • Use config-based to decide which event should start and report. maybe control behavior as well.
  • Flash API on Android.


From npm package: npm install react-native-incall-manager
From git package: npm install git://



note: you might need android.permission.BLUETOOTH permisions for Bluetooth to work.

After install, you can use rnpm (npm install rnpm -g) to link android.
use react-native link react-native-incall-manager to link or manually if you like.

We use android support library v4 to check/request permissions.
You should add compile "$YOUR_VERSION" in $YOUR_PROJECT/android/app/build.gradle dependencies on android.

Manually Linking

If react-native link doesn't work, ( see: ) please add it manually in your main project:

  1. In android/app/build.gradle
    Should have a line compile(project(':react-native-incall-manager')) in dependencies {} section

  2. In android/settings.gradle
    Should have:

    include ':react-native-incall-manager'
    project(':react-native-incall-manager').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-incall-manager/android')
  3. In

    import com.zxcpoiu.incallmanager.InCallManagerPackage;
    private static List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
            new MainReactPackage(),
            new InCallManagerPackage(),

Optional sound files on android

If you want to use bundled ringtone/ringback/busytone sound instead of system sound,
put files in android/app/src/main/res/raw
and rename file correspond to sound type:


On android, as long as your file extension supported by android, this module will load it.



react-native link react-native-incall-manager

Using CocoaPods

Update the following line with your path to node_modules/ and add it to your Podfile:

pod 'ReactNativeIncallManager', :path => '../node_modules/react-native-incall-manager'

Manually Linking

In case react-native link doesn't work,

  • Drag node_modules/react-native-incall-manager/ios/RNInCallManager.xcodeproj under <your_xcode_project>/Libraries
  • Select <your_xcode_project> --> Build Phases --> Link Binary With Libraries
    • Drag Libraries/RNInCallManager.xcodeproj/Products/libRNInCallManager.a to Link Binary With Libraries
  • Select <your_xcode_project> --> Build Settings
    • In Header Search Paths, add $(SRCROOT)/../node_modules/react-native-incall-manager/ios/RNInCallManager

Clean project if messed up:

The installation steps are a bit complex, it might be related your xcode version, xcode cache, converting swift version, and your own path configurations. if something messed up, please follow steps below to clean this project, then do it again steps by steps.

  1. Delete all project/directory in xcode related to incall-manager
  2. Delete react-native-incall-manager in node_modules ( rm -rf )
  3. Xcode -> Product -> clean
  4. Close xcode
  5. Run npm install again
  6. Open xcode and try the install process again steps by steps

If someone knows a simpler way to set this project up, let me know plz.

Optional sound files on iOS

If you want to use bundled ringtone/ringback/busytone sound instead of system sound

  1. Add files into your_project directory under your project's xcodeproject root. ( or drag into it as described above. )
  2. Check copy file if needed
  3. Make sure filename correspond to sound type:

On ios, we only support mp3 files currently.


This module implements a basic handle logic automatically, just:

import InCallManager from 'react-native-incall-manager';

// --- start manager when the chat start based on logics of your app 
// On Call Established:
InCallManager.start({media: 'audio'}); // audio/video, default: audio

// ... it will also register and emit events ...

// --- On Call Hangup:
// ... it will also remove event listeners ...

If you want to use ringback:

// ringback is basically for OUTGOING call. and is part of start().

InCallManager.start({media: 'audio', ringback: '_BUNDLE_'}); // or _DEFAULT_ or _DTMF_
//when callee answered, you MUST stop ringback explicitly:

If you want to use busytone:

// busytone is basically for OUTGOING call. and is part of stop()
// If the call failed or callee are busing,
// you may want to stop the call and play busytone
InCallManager.stop({busytone: '_DTMF_'}); // or _BUNDLE_ or _DEFAULT_

If you want to use ringtone:

// ringtone is basically for INCOMING call. it's independent to start() and stop()
// if you receiving an incoming call, before user pick up,
// you may want to play ringtone to notify user.
InCallManager.startRingtone('_BUNDLE_'); // or _DEFAULT_ or system filename with extension

// when user pickup

// or user hangup

Also can interact with events if you want: See API section.

import { DeviceEventEmitter } from 'react-native';

DeviceEventEmitter.addListener('Proximity', function (data) {
    // --- do something with events

Automatic Basic Behavior:

On start:

  • Store current settings, set KeepScreenOn flag = true, and register some event listeners.
  • If media type is audio, route voice to earpiece, otherwise route to speaker.
  • Audio will enable proximity sensor which is disabled by default if media=video
  • When proximity detects user close to screen, turn off screen to avoid accident touch and route voice to the earpiece.
  • When newly external device plugged, such as wired-headset, route audio to an external device.
  • Optional play ringback

On stop:

  • Set KeepScreenOn flag = false, remote event listeners, restore original user settings.
  • Optionally play busytone

Custom Behavior:

You can customize behavior using API/events exposed by this module. See API section.

Note: iOS only supports auto currently.



Method android ios description
start({media: ?string, auto: ?boolean, ringback: ?string}) 😄 😄 start incall manager. ringback accept non-empty string or it won't playdefault: {media:'audio', auto: true, ringback: ''}

setForceSpeakerphoneOn(flag: ?boolean) 😄 😄 true -> force speaker on false -> force speaker off null -> use default behavior according to media typedefault: null
setMicrophoneMute(enable: ?boolean) 😄 😡 mute/unmute micophonedefault: falsep.s. if you use webrtc, you can just use track.enabled = false to mute
async getAudioUriJS() 😄 😄 get audio Uri path. this would be useful when you want to pass Uri into another module.
startRingtone(ringtone: string, ?vibrate_pattern: array, ?ios_category: string, ?seconds: number) 😄 😄 play ringtone. ringtone: 'DEFAULT' or 'BUNDLE'vibrate_pattern: same as RN, but does not support repeatios_category: ios only, if you want to use specific audio categoryseconds: android only, specify how long do you want to play rather than play once nor repeat. in sec.
stopRingtone() 😄 😄 stop play ringtone if previous started via startRingtone()
stopRingback() 😄 😄 stop play ringback if previous started via start()
setFlashOn(enable: ?boolean, brightness: ?number) 😡 😄 set flash light on/off
async getIsWiredHeadsetPluggedIn() 😡 😄 return wired headset plugged in state


Event android ios description
'Proximity' 😄 😄 proximity sensor detected changes.
data: {'isNear': boolean}
'WiredHeadset' 😄 😄 fire when wired headset plug/unplug
data: {'isPlugged': boolean, 'hasMic': boolean, 'deviceName': string }
'NoisyAudio' 😄 😡 see andriod doc.
data: null
'MediaButton' 😄 😡 when external device controler pressed button. see android doc
data: {'eventText': string, 'eventCode': number }
'onAudioFocusChange' 😄 😡 see andriod doc

NOTE: platform OS always has the final decision, so some toggle API may not work in some cases be careful when customizing your own behavior
