Android: FileObserver monitors only top directory
android, android-sdcard, fileobserver
Solution
According to the documentation
The documentation is incorrect, as is noted in this issue.
Is there any problem with the code?
No, but `FileObserver` is not recursive, despite the documentation to the contrary.
Problem
According to the documentation, ``` "Each FileObserver instance monitors a single file or directory. If a directory is monitored, events will be triggered for all files and subdirectories inside the monitored directory." ``` My code goes like, ``` FileObserver fobsv = new FileObserver("/mnt/sdcard/") { @Override public void onEvent(int event, String path) { System.out.println(event+" "+path); } }; fobsv.startWatching(); ``` However, the `onEvent()` is triggering only when a file is changed in the /mnt/sdcard/. If I create a file in /mnt/sdcard/downloads/, the method is not getting fired. Is there any problem with the code?
