Apps Is it possible to get notification when the content of a regular file is changed

[websurf]

As the title, when the content of any regular file is changed, is it possible to get notification?

Thanks.

I think you are looking for android.os.FileObserver.
You implement a subclass of it, which implements onEvent().
Then you construct a new instance of this class with the file path and maybe flags as parameters. After calling startWatching() your callback should be invoked with file changes.

Thanks for you replay, I ever tried FileObserver, it only can monitor the registered file or files just under the registered path, But I want to monitor the files under the registered path RECUSIVELY.
