Android and JFileChooser

Question

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.

Answer 1

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

Answer 2

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
