Android and JFileChooser

I've developed a desktop application that allows the user to extract images from their phone.

When I first started this project, my android was running Gingerbread. When I plugged my phone into the laptop via USB, it would appear as a "Device with removable storage". Therefore, the JFileChooser would pick it up.

nwdir = new JFileChooser();
            nwdir.setCurrentDirectory(new java.io.File("C:\\"));
            nwdir.setDialogTitle(choosertitle);
            nwdir.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
            nwdir.setAcceptAllFileFilterUsed(true);

However, I recently upgraded the phone's o/s to Icecream and it now shows up on the desktop as a "portable device". This is something that the JFileChooser cannot see?!

Has anyone got any suggestions on how to get around this problem? I was going to roll back the O/S of the phone, but this somewhat limits the application's device support.

I've found a way around it by doing this.... Settings > Wireless & Network > USB utilities and click the button > then (and ONLY then) plug in USB cable

The default transfer mode has been changed in Android 4.0 Ice Cream Sandwich from USB Mass Storage mode to MTP (Media Transfer Protocol) which doesn't use a standard filesystem mount. On some phones it is possible to change the USB mode while on others it may be necessary to install an apk to enable it
