我正在使用firebase云消息传递将通知发送到我的应用程序。我在前景中的应用程序中获取通知,然后切换到另一个应用程序(我的应用程序在后台运行的应用程序未关闭)。但是,当我从最近的二手应用中删除时。我没有收到通知。我也获得了令牌ID。当从最新的使用应用程序中删除应用程序时,问题没有得到通知。

您要问的是FCM上不支持的(这曾与GCM一起使用,而GCM现在已弃用)
https://developer.android.com/about/versions/android-3.1#launchcontrols:
请注意,系统将flag_exclude_stopped_packages添加到所有 广播意图。这样做是为了防止从后台广播 来自无意或不必要地启动组件的服务 停止的申请。背景服务或应用程序可以 通过添加flag_include_stopped_packages来覆盖此行为 标志以广播意图,应允许激活停止 应用。
应用程序首次安装时处于停止状态,但是 尚未启动以及用户手动止步 (在管理应用程序中)。
广播FCM触发器的FLAG_EXCLUDE_STOPPED_PACKAGES设置为true,如果用户停止了强制,则有效地不会唤醒您的应用程序(就像您一样)。
有人要求使用firebase允许用户控制此标志 - 但这是由开发团队
