onCallListener etc.

[CMLCNL]

Hello is facing a problem that I do not understand. We have functions related to calls. onCallListener etc. For example, if the application remains open on the frontend or in the background, it will not be triggered when a call is received after 10 or 15 minutes. I think he's dying. What can I do to keep it active all the time? or what can i do to revive it with notification?

For example, I talked to someone for 20 minutes. Then I closed the call. If someone else calls me after this call, they cannot connect to me because the listeners are not working. @ccvlad What do you think about this problem?

@CMLCNL See this answer.

I use the code below to enable/disable call activity in background:

...
backgroundModeOptions =  {
  taskName: 'AppName',
  taskTitle: 'You have an active call',
  taskDesc: 'Press to return',
  taskIcon: {
    name: 'ic_launcher',
    type: 'mipmap',
  },
  linkingURI: 'appname://foreground', // see the guide to configure deep linking
};

startBackgroundMode = () => {
  this.stopBackgroundMode();

  BackgroundService.start(async (params) => {
    await new Promise(async () => {});
  }, this.backgroundModeOptions);
};

stopBackgroundMode = () => {
  if (BackgroundService.isRunning()) {
    return BackgroundService.stop();
  }
};
...

To receive call if your app is closed:

• Setup push notification for your app first (guide).
• Send push on start call to user you are calling (send push).
• When application is active and chat connection is in connected state you receive a call via listeners. If your app goes to background you should follow this guide to enable push notification cause system will close chat connection after some time in inactive state.
• https://developers.connectycube.com/reactnative/videocalling?id=receive-a-call-in-background

You will receive a call to onCallListener after chat will be connected and videochat listeners will be inited

I guess you didn't understand me. Now you open the app for example and then throw the app to the background in iOS. 10-15 minutes passed. Then if you call this phone. no way listeners work.

I just tried to answer more explained)

Try the code below (need to setup push notification):

import {AppState, ...} from 'react-native';
...
  componentDidMount = () => {
    this.setupAppStateListener();
  }

  componentWillUnmount = () => {
    this.removeAppStateListener();
  }

  setupAppStateListener = () => {
    AppState.addEventListener('change', this.handleAppStateChange);
  };

  removeAppStateListener = () => {
    AppState.removeEventListener('change', this.handleAppStateChange);
  };

  handleAppStateChange = (state) => {
    if (state === 'inactive') {
      // Ignore, handle only 'active' and 'background'
      // https://facebook.github.io/react-native/docs/appstate
      return;
    }

    if (state === 'background') { // app goes to background/inactive
      if (ConnectyCube.chat.isConnected) { // checks is we are able to send request via chat
        ConnectyCube.chat.markInactive(); // status inactive (offline) to an ability to receives push notification for app in tray.
        // you are able to receive push to show CallKit (or open your app by tap on push notification about incoming call).
      }
    } else { // app returns from background (active)
       if (ConnectyCube.chat.isConnected) {
        ConnectyCube.chat.markActive(); // status active (online)
      } else {
        ConnectyCube.chat.connect(params); // reconnect if chat connection was closed
      }
      // onCallListener, onRemoteStreamListener etc. will works after...
    }
  };
...
