Android 應用程序未通過 Firebase FCM 接收推送通知

[英]Android App do not receive push notification trough Firebase FCM

問題描述

更新一：

當應用程序在屏幕上時不會收到通知，只會在前台收到通知。 如果應用程序正在屏幕上運行，則會發生以下情況：

這是我在手機屏幕上看到的。

在此處輸入圖片說明

這是日志貓

我正在嘗試通過 Firebase FCM 服務為我的應用實現推送通知服務，但不幸的是，它不起作用。

發生了什么，應用程序中沒有任何內容，它不會崩潰，但也不會收到我從 Firebase 控制台發送的任何通知。

我將附上我的應用程序中的所有相關文件。
