当应用程序处于React Native中的Kill状态时，Fcm通知不会出现-Java 学习之路

当从FCM发送时，Firebase控制台以反应原生方式发送，它很容易进入iOS和Android，但当我从管理员或后端发送通知时，当应用程序处于终止状态时，它不会出现 . 我正在使用react-native-fcm .

Thanx .

我有同样的问题，通过在收到fcm令牌后添加下面的代码来解决它，

FCM.setBadgeNumber(0);

以上是针对Android的iOS，您需要在Xcode中打开背景通知 .
enter image description here
在Xcode中选择您的项目并打开功能，看看是否有背景模式 . 请参阅屏幕截图

这是我使用的代码片段

export const MyNotificationReceiver = props => {
  FCM.getInitialNotification().then(notif => {
  });

  FCM.setBadgeNumber(0); //Add this for background notification

  this.notificationListener = FCM.on(FCMEvent.Notification, async notif => {
    var notification_messgae = "";
    try {
      notification_messgae = notif.default;
    } catch (error) {
      notification_messgae = JSON.stringify(notif);
    }
    if (osDetection) {
      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;
      }
    }
    if (!osDetection()) {
      if(notif.default)
      {
        FCM.presentLocalNotification({
          body: notif.default,
          priority: "high",
          show_in_foreground: true,
          large_icon: "noti_icon",                           // Android only
          icon: "noti_icon",                                // as FCM payload, you can relace this with custom icon you put in mipmap
          android_actions: JSON.stringify([{
            id: "view",
            title: 'view'
          }, {
            id: "dismiss",
            title: 'dismiss'
          }]) // for android, take syntax similar to ios's. only buttons are supported
        });
       }

    }
  });
};
