Can you say what is required (compile params, flags, etc..) exactly?

AFAIK file descriptor is process-related and it means nothing in context of another process - see here<http://stackoverflow.com/questions/16939607/how-to-pass-file-descriptor-from-usbdeviceconnection-to-native-code-on-android> and here<http://stackoverflow.com/questions/16963237/passing-usb-file-descriptor-to-android-ndk-program> .
