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.

推荐答案

您应该使用 FileObserver 监视文件或目录的更改.

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

似乎有一个示例此处，但是我还没有尝试过，所以不能保证它的正确性.

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