Android issue. App doesn't receive notification in unloaded(killed) state

[stsiushkevich]

RN: 0.42.0 react-native-fcm: 7.4.0 Android

When the application is in the unloaded state my event handler doesn't trigger.

This is my code:

  addPushNotificationReceivedEventListener (handler) {
    const isIOS = this.isIOS()
    if (handler) {
      return FCM.on(FCMEvent.Notification, n => {
        setTimeout(() => { handler(n) }, 500)

        if (isIOS) {
          switch (n._notificationType) {
            case NotificationType.Remote:
              n.finish(RemoteNotificationResult.NewData)
              break
            case NotificationType.Local:
              n.finish()
              break
            case NotificationType.NotificationResponse:
              n.finish()
              break
            case NotificationType.WillPresent:
              n.finish(WillPresentNotificationResult.All)
              break
          }
        }
      })
    }
    return null
  }

@Override
public void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    this.setIntent(intent);
}

This code doesn't solve the problem

I have found https://github.com/evollu/react-native-fcm/issues/504 and https://github.com/evollu/react-native-fcm/issues/531 issues but these approaches don't work.

unloaded state I assume when app is killed? did you run your listener outside of component lifecycle?

[stsiushkevich]

Ok. But Android receives notification in the system tray without triggering my handler with an incorrect icon. How can I set it?

[evollu]

I assume incorrect icon means a white icon? You need to make a white only icon for notification for Lollipop+, check readme

You need to run your listener outside of component lifecycle to have the callback triggered when app is not running.

OOO thank you! I'm going to try it right now!

Unfortunately, I cannot get such behavior when my handler trigger when the app is in the killed state.

// PushNotificationUtils.js
export default class PushNotificationUtils {
  static sendLocalNotification (data) {
    FCM.presentLocalNotification({...data,
      ...{
        sound: 'default',
        click_action: 'ACTION',
        priority: 'high',
        auto_cancel: true,
        large_icon: 'ic_launcher',
        icon: 'info',
        vibrate: 300,
        show_in_foreground: true
      }
    })
  }

  static addPushNotificationReceivedEventListener (handler) {
    if (handler) {
      return FCM.on(FCMEvent.Notification, n => {
        setTimeout(() => { handler(n) }, 500)

        if (isIOS()) {
          switch (n._notificationType) {
            case NotificationType.Remote:
              n.finish(RemoteNotificationResult.NewData)
              break
            case NotificationType.Local:
              n.finish()
              break
            case NotificationType.NotificationResponse:
              n.finish()
              break
            case NotificationType.WillPresent:
              n.finish(WillPresentNotificationResult.All)
              break
          }
        }
      })
    }
    return null
  }
}

//myapp.js
PushNotificationUtils.addPushNotificationReceivedEventListener((n) => {
  if (isValidNotification(n)) {
    if (+n.id === 3) {
      VersionCheck.needUpdate()
        .then(res => {
          if (res.isNeeded) Linking.openURL(VersionCheck.getStoreUrl())
        })
    } else {
      appAuthToken.getSessionToken().then(token => {
        let { userId } = token.sessionToken.data
        if (userId === +n.userId) {
          const isFromTray = n.opened_from_tray
          const custom = PushNotificationParseUtils.getCustomData(n)
          if (isFromTray) {
            PushNotificationStore.pushNotification(custom)

            if (isIOS() && isAppActive()) {
              Actions.ConfirmAuthorizationPopup({ modalSceneName: CONFIRM_AUTHORIZATION, isVisible: true })
            }
          }

          const isLocal = n.local_notification
          if (!(isLocal || isFromTray)) {
            let {title, body} = PushNotificationParseUtils.getMainData(n)
            PushNotificationUtils.sendLocalNotification({...{title, body, big_text: body}, ...custom})
          }
        }
      })
    }
  }
})

export default function native (platform) {
  class MyApp extends Component {
    render () {
      const store = configureStore(getInitialState())

      store.dispatch(setPlatform(platform))
      store.dispatch(setVersion(VERSION, versionHead))
      store.dispatch(setManufacturer(DeviceInfo.getManufacturer()))
      store.dispatch(setSystemVersion(DeviceInfo.getSystemVersion()))
      store.dispatch(setDeviceId(DeviceInfo.getDeviceId()))

      return (
        <Provider store={store}>
          <RouterWithRedux
            scenes={scenes}
            sceneStyle={styles.scene}
            backAndroidHandler={() => {
                   //a code
            }} />
        </Provider>
      )
    }
  }
  AppRegistry.registerComponent('myapp', () => MyApp)
}

It doesn't still trigger when the app is killed - it only works in background and foreground app state :(. Maybe is this impossible? Or I have old version of library?

About icon. Yes - it is white. I can set it with tag in for default icon. You set large icon with notification.setLargeIcon(largeIconBitmap); in javaFIRLocalMessagingHelper class. Can I use similar api in my manifest file? For example: <meta-data android:name="com.google.firebase.messaging.large_icon" android:resource="@mipmap/ic_launcher" />? Does such ability exist?

[evollu]

ah yes. need react-native-fcm 8+ I think

for large_icon. I'm not sure. perhaps not because FCM SDK doesn't support large icon. You can check if android itself has a way to set default large icon. otherwise you need to use custom_notification, then you can pass large_icon property

[stsiushkevich]

Ok.. thank you! I think setting large_icon property in my version of library won't set my custom icon because in the killed state of app code of your library won't trigger. Furthermore, I think react-native-fcm v8.0.0 will work exactly same as my version in the case when the app is killed because I didn't find any significant changes in v8.0.0 android source code. I cannot upgrade my project to react-native 0.47.0+ because many of my libraries will crash((

[evollu]

feel free to upgrade to latest if your rn is > 0.40, the latest code fixed compatibility issue

[shekharskamble]

@stsiushkevich is your issue resolved? facing same problem... cant get FCM.on if app is killed...
