For your main Question
Follow -

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

Quote:
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.

For Logger in Android
Refer - Logger[^]

Quote:
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.
