RN Incoming Call Version 2

React Native module to display custom incoming call activity, best result when using with firebase background messaging. Only for Android since iOS we have VoIP.

Yes I heard you could use self managed ConnectionService thing. But since I'm not an Android expert, this is a solution I found acceptable.

You could also wait for this feature request from react-native-callkeep to be resolved and have an easier life.

Version 2 Breaking Changes

Hello there! It's been a while since I first public version 1 of this library, which contains some bugs that I don't have much time to fix.

Luckily I got a client project which needs this feature again and now I have time to improve it and make sure all major features work. So here is most of it I guess:

• More generic incoming call UI.

• Work nicely with all application state (foreground, background, killed, locked).

• More flexible APIs.

Thanks to jpudysz's folk of react-native-callkeep, version 2 is heavily depended on it.

Migrate from v1

• getLaunchParameters() & clearLaunchParameters() is now replaced by openAppFromHeadlessMode() & getExtrasFromHeadlessMode().

• Answer calls from background / killed state no longer open app and send launchParams, you need to listen to answerCall event from headless job and trigger backToForeground or openAppFromHeadlessMode manually.

Getting started

$ npm install react-native-incoming-call --save

or

$ yarn add react-native-incoming-call

Addition installation step

In AndroidManifest.xml:

• Add <activity android:name="com.incomingcall.UnlockScreenActivity" /> line between <application> tag.

• Add <uses-permission android:name="android.permission.VIBRATE" /> permission.

• Also, it's recommend to put android:launchMode="singleInstance" in <activity android:name=".MainActivity"... tag to prevent duplicate activities.

For RN >= 0.60, it's done. Otherwise:

$ react-native link react-native-incoming-call

Usage

In App.js:

import {useEffect} from 'react';
import {DeviceEventEmitter, Platform} from 'react-native';
import IncomingCall from 'react-native-incoming-call';
 
// Listen to cancel and answer call events
useEffect(() => {
  if (Platform.OS === "android") {
    /**
     * App open from killed state (headless mode)
    */
    const payload = await IncomingCall.getExtrasFromHeadlessMode();
    console.log('launchParameters', payload);
    if (payload) {
      // Start call action here. You probably want to navigate to some CallRoom screen with the payload.uuid.
    }
 
    /**
     * App in foreground / background: listen to call events and determine what to do next
    */
    DeviceEventEmitter.addListener("endCall", payload => {
      // End call action here
    });
    DeviceEventEmitter.addListener("answerCall", payload => {
      // Start call action here. You probably want to navigate to some CallRoom screen with the payload.uuid.
    });
  }
}, []);

In index.js or anywhere firebase background handler lies:

import messaging from '@react-native-firebase/messaging';
import {DeviceEventEmitter} from 'react-native';
import IncomingCall from 'react-native-incoming-call';
 
messaging().setBackgroundMessageHandler(async remoteMessage => {
  // Receive remote message
  if (remoteMessage?.notification?.title === 'Incoming Call') {
    // Display incoming call activity.
    IncomingCall.display(
      'callUUIDv4', // Call UUID v4
      'Quocs', // Username
      'https://avatars3.githubusercontent.com/u/16166195', // Avatar URL
      'Incomming Call', // Info text
      20000 // Timeout for end call after 20s
    );
  } else if (remoteMessage?.notification?.title === 'Missed Call') {
    // Terminate incoming activity. Should be called when call expired.
    IncomingCall.dismiss();
  }
 
  // Listen to headless action events
  DeviceEventEmitter.addListener("endCall", payload => {
    // End call action here
  });
  DeviceEventEmitter.addListener("answerCall", (payload) => {
    console.log('answerCall', payload);
    if (payload.isHeadless) {
      // Called from killed state
      IncomingCall.openAppFromHeadlessMode(payload.uuid);
    } else {
      // Called from background state
      IncomingCall.backToForeground();
    }
  });
});

Well-known issues

Incoming screen not show on android > 9:

You need to turn on autostart and display pop-up windows permissions manually. I'm searching for a better solution.

No vibration when screen locked:

PR is welcomed! 😂
