android file monitor

To track changes to an Android folder, use the FileObserver class >

A possible implementation would look like this:

public class FileMonitor extends FileObserver {

    public MyFileObserver(String path) {

        super(path, FileObserver.ALL_EVENTS);
    }

    @Override
    public void onEvent(int event, String path) {

        if (path == null) {
            return;
        }

        if ((FileObserver.CREATE & event)!=0) {

            //Foi criado um novo ficheiro ou uma nova pasta.
            //Introduza aqui o código para o tratamento que quer
            //efectuar para este caso 
        }

    }

}

In this example, you are only monitoring whether a new file or folder has been created within the monitored folder.

Other events can be monitored, see the documentation .

To use do:

FileMonitor monitor = new FileMonitor("/sdcard/minhaPasta/");
monitor.startWatching();

To stop monitoring use:

monitor.stopWatching();

You will need a broadcast receiver that will give you the information that a new photo was taken. That is, whenever a photo is taken you will have such information and will call the upload code for FTP

If the photo example is your real problem you can try this: link

Inside the onReceive of your broadcast is where you should list the photos and search for the new photo.
