推送通知未显示在Android前景中

我在Android和iPhone中使用react-native-fcm进行远程通知.

I've used react-native-fcm for remote notification in android and iPhone.

react-native-fcm

在Android前台中，我无法在通知栏中获得远程通知.

In Android foreground I'm not be able to getting remote notification in notification bar.

在后台模式下，我能够成功获取通知，但在前台却不能.

In background mode I'm able to getting notification successfully but some how in foreground doesn't.

最近两个月以来，我一直在遭受这个问题的困扰，但由于我进行了许多新的尝试来解决问题，但最终没有获得成功，因此我无法像以前那样获得很好的解决方案.

I'm suffering this issue from last 2 months and not get it well solution for the same as i doing so many new attempt to resolve issue but at the end not getting any succeed.
