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.

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.

• 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.

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

or

$ yarn add react-native-incoming-call

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

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(); } }); });

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

PR is welcomed! 😂
