1. Get notification before deleting the file in Android[^]
2. Get notification using file observer[^]

答案

不，不是。观察者只会告诉你已发生的事情。在删除之前拦截删除的唯一方法是编写要加载到系统上的设备驱动程序或者使用删除文件的程序启动的C库。

Answer
No, it’s not. The observer will simply tell you what’s already happened. The only way to intercept the deletion before it happens is to write either a device driver to be loaded on the system or a C library that’s started with the program that’s deleting the file.

适用于Android的记录器

记录器用于将记录记录到各种目的地，例如日志文件或控制台。他们使用处理程序的实例[ ^ ]实际执行特定于目标的操作。

Loggers are used to log records to a variety of destinations such as log files or the console. They use instances of Handler[^] to actually do the destination-specific operations.
