Appendix CSource codeC.1 USBMonitorThe USBMonitor application was built as a proof of concept for detectingwhen USB debugging is in use. It listens to the intent broadcast [2] used bythe Android system to inform applications that the USB state has changed(called UsbManager.ACTION USB STATE), and the low-level Uevents generatedby the Linux kernel when the hardware configuration changes.
