FCM背景同步失败:AUTHENTICATION_FAILED [英] FCM background sync failed: AUTHENTICATION_FAILED

问题描述

我尝试使用FCM在Android上获取实时通知.当我尝试使用模拟器运行应用程序时，通知消息会正确显示.但是当我在真实设备(小米红米手机注3)上尝试时，没有出现通知.令牌始终返回null，并且出现此错误:

I tried to get real time notification on Android using FCM. When I try running my app using emulator, notification message appear correctly. but when I try it on real device (xiaomi redmi note 3), the notification doesn't appear. The token always return null, and I get this error:

FCM background sync failed: AUTHENTICATION_FAILED

我曾经尝试阅读所有相同的问题，但是出现此问题的原因有两个:

I've been to try read all same problem, there are 2 reasons why the problem appears:

1. 设备没有Google Play服务
2. 没有互联网连接

但是我确定我的设备具有Google Play服务并已连接到互联网，但是问题仍然存在.

but I'm sure that my device have Google Play Services and is connected to internet, but the problem still exists.

我该如何解决这个问题?任何建议将不胜感激.

How can I solve this problem? Any suggestion would be appreciated.
