推荐答案

为所有设备支持Fire-base推送通知就像一个迷宫. 推送通知有3种情况

Supporting Fire-base push notification for all device is like a maze. There are 3 scenario for push notification

1. 前景(触发FirebaseMessagingService的onMessageReceived方法)
2. 背景(无法触发FirebaseMessagingService，但firebase服务将其消息推送到设备的通知托盘)
3. 应用程序杀死(无法触发FirebaseMessagingService firebase服务推送将其消息推送到设备的通知托盘)

1. Foreground (fire FirebaseMessagingService's onMessageReceived method)
2. Background (can't fire FirebaseMessagingService but firebase service push their message into device's Notification Tray)
3. App kill (can't fire FirebaseMessagingService firebase service push push their message into device's Notification Tray)

注意:当您从后台堆栈中滑出时，某些中文设备(如小米，华硕，华为等)会强制停止您的应用程序，从而导致该服务被终止.因此，firebase服务无法运行，并且无法将其通知推送到通知"托盘.

NOTE: Some chinese device like Xiaomi, Asus, Huawei etc. are force stop your app when you swipe out from your background stack, so that the service is kill. For that reason firebase service is not run and can't push their notification into Notification tray.

在小米中-安全->权限->自动启动，然后选中您的应用.启用此功能意味着应用程序的任何服务始终在后台运行.然后，您每次都会从应用程序中收到各种通知.

In Xiaomi - security-->permissions-->autostart then check mark your app. Enable this means app's any service always run in background. Then you get all kinds of notification from your app every time.
