Android FileObserver for monitoring other apps?

问题:

I suspect that I already know the answer to this question, but I wanted to ask the experts anyway.

Would it be possible to use the FileObserver class to monitor changes to files belonging to other apps (i.e. things in the /data directory that don't belong to the app implementing the FileObserver)?

It seems that even if I had a rooted device, there isn't a way to have my monitoring application run as root.

The only possible (and unappealing) solution I've come up with, is having a rooted device, and changing the privileges on all the files on the device so that they would be accessible by the monitoring app.

Thanks, Jarabek

This would almost certainly have to be done in native code, and would only work on rooted devices.

You should look into inotify.
