File System Listener

Question

I would like to know if it is possible to have a listener in my application for notifying events when a file is added to the file system. Can someone kindly guide me with this.<

Answer 1

You should use a FileObserver to monitor for changes to files or directories.

There seems to be an example here, but I've not tried it so can't vouch for it's correctness.

Answer 2

try this:

new FileObserver(path) {
    @Override
    public void onEvent(int event, String path) {
        if (event == FileObserver.CREATE)
            Toast.makeText(getActivity(), "File created", Toast.LENGTH_SHORT).show();
        }
    }.startWatching();
