firebase - 当应用程序处于后台或关闭时，反应本机推送通知不显示横幅（屏幕上弹出）

Question

我正在使用react-native-push-notification并遵循其文档。当应用程序在前台时它工作正常但是当应用程序在后台并且我尝试从firebase控制台发送通知时，它只是在状态栏中显示了应用程序的一个小图标但不显示横幅

我尝试添加一个新频道但仍然无法正常工作

componentDidMount() {

        NetInfo.isConnected.addEventListener('connectionChange', this.handleConnectivityChange);

        PushNotification.configure({

            // (optional) Called when Token is generated (iOS and Android)
            onRegister: function(token) {
                console.log( 'TOKEN:', token );
            },

            // (required) Called when a remote or local notification is opened or received
            onNotification: function(notification) {
                console.log( 'NOTIFICATION:', notification );

                Platform.OS === 'ios' ? notification.finish(PushNotificationIOS.FetchResult.NoData) : null;
            },

            // ANDROID ONLY: GCM or FCM Sender ID (product_number) (optional - not required for local notifications, but is need to receive remote push notifications)
            senderID: Variables.GCM_SENDER_ID,

            // IOS ONLY (optional): default: all - Permissions to register.
            permissions: {
                alert: true,
                badge: true,
                sound: true
            },

            visibility: 'public',

            popInitialNotification: true,

            requestPermissions: true,
        });
    }
