不从 firebase 实时数据库中删除消息

问：

在从 android studio 创建聊天应用程序时，Jawa 和 firebase 消息不会从 firebase 中删除。 当应用程序在android设备上运行并发出命令（从程序和firebase控制台）以从firebase Realtime Database删除消息时，一旦它们被删除，但同时，它们再次出现在firebase中。 当应用程序未在设备中运行时，它们将从控制台中删除（单击从 firebase 中删除节点）。

在 firebase 实时数据库规则中，我还向每个人授予了读写权限（即将读写设置为 true）

请帮我解决这个问题

我已经尝试了很多，使用不同的线程进行删除（使用删除以及设置值空命令进行删除）和更改 firebase 的规则，但是当应用程序在设备上运行时，我没有得到删除消息的结果。 请提供相同的解决方案。
