问如何以编程方式实现USB tethering/debugging启用？

EN

    public void enableTethering() {

                    Object conService= getSystemService(Context.CONNECTIVITY_SERVICE);
                    for (Method m : obj.getClass().getDeclaredMethods()) {

                        if (m.getName().equals("tether")) {
                            try {
                                m.invoke(conService, "usb0");
                            } catch (IllegalArgumentException |  
                                 IllegalAccessException | InvocationTargetException   e) {

                                e.printStackTrace();

                        }
                    }
            }
