在Android上接收推送通知时，应用程序崩溃

Question

我正在使用React Native为Android和iOS开发一个应用程序，我在这里使用react-native-fcm：https://github.com/evollu/react-native-fcm，但由于某些原因，应用程序崩溃时接收推送通知时应用程序崩溃前景状态/开放！ 当app关闭时，它可以在后台运行！

React Native app：

 componentDidMount() {
    // iOS: show permission prompt for the first call. later just check permission in user settings
    // Android: check permission in user settings
    FCM.requestPermissions().then(()=>console.log('granted')).catch(()=>console.log('notification permission rejected'));

    FCM.getFCMToken().then(token => {
        console.log(token)
        // store fcm token in your server
    });

    this.notificationListener = FCM.on(FCMEvent.Notification, async (notif) => {
        // optional, do some component related stuff
    });

    // initial notification contains the notification that launchs the app. If user launchs app by clicking banner, the banner notification info will be here rather than through FCM.on event
    // sometimes Android kills activity when app goes to background, and when resume it broadcasts notification before JS is run. You can use FCM.getInitialNotification() to capture those missed events.
    // initial notification will be triggered all the time even when open app by icon so send some action identifier when you send notification
    FCM.getInitialNotification().then(notif => {
       console.log(notif)
    });
}

componentWillUnmount() {
    // stop listening for events
    this.notificationListener.remove();
}
import FCM, {FCMEvent, RemoteNotificationResult, WillPresentNotificationResult, NotificationType} from 'react-native-fcm';

// this shall be called regardless of app state: running, background or not running. Won't be called when app is killed by user in iOS
FCM.on(FCMEvent.Notification, async (notif) => {
    // there are two parts of notif. notif.notification contains the notification payload, notif.data contains data payload
    if(notif.local_notification){
      //this is a local notification
    }
    if(notif.opened_from_tray){
      //iOS: app is open/resumed because user clicked banner
      //Android: app is open/resumed because user clicked banner or tapped app icon
    }
    // await someAsyncCall();

    if(Platform.OS ==='ios'){
      //optional
      //iOS requires developers to call completionHandler to end notification process. If you do not call it your background remote notifications could be throttled, to read more about it see https://developer.apple.com/documentation/uikit/uiapplicationdelegate/1623013-application.
      //This library handles it for you automatically with default behavior (for remote notification, finish with NoData; for WillPresent, finish depend on "show_in_foreground"). However if you want to return different result, follow the following code to override
      //notif._notificationType is available for iOS platfrom
      switch(notif._notificationType){
        case NotificationType.Remote:
          notif.finish(RemoteNotificationResult.NewData) //other types available: RemoteNotificationResult.NewData, RemoteNotificationResult.ResultFailed
          break;
        case NotificationType.NotificationResponse:
          notif.finish();
          break;
        case NotificationType.WillPresent:
          notif.finish(WillPresentNotificationResult.All) //other types available: WillPresentNotificationResult.None
          break;
      }
    }
});
FCM.on(FCMEvent.RefreshToken, (token) => {
    console.log(token)
    // fcm token may not be available on first load, catch it here
});
