copied!<p>you can also use reflection to access the hidden function for setting usb tethering. Here is my code.</p> <pre><code> ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE); Log.d(TAG,"test enable usb tethering"); String[] available = null; int code=-1; Method[] wmMethods = cm.getClass().getDeclaredMethods(); for(Method method: wmMethods){ if(method.getName().equals("getTetherableIfaces")){ try { available = (String[]) method.invoke(cm); break; } catch (IllegalArgumentException e) { // TODO Auto-generated catch block e.printStackTrace(); return; } catch (IllegalAccessException e) { // TODO Auto-generated catch block e.printStackTrace(); return; } catch (InvocationTargetException e) { // TODO Auto-generated catch block e.printStackTrace(); return; } } } for(Method method: wmMethods){ if(method.getName().equals("tether")){ try { code = (Integer) method.invoke(cm, available[0]); } catch (IllegalArgumentException e) { // TODO Auto-generated catch block e.printStackTrace(); return; } catch (IllegalAccessException e) { // TODO Auto-generated catch block e.printStackTrace(); return; } catch (InvocationTargetException e) { // TODO Auto-generated catch block e.printStackTrace(); return; } break; } } if (code==0) Log.d(TAG,"Enable usb tethering successfully!"); else Log.d(TAG,"Enable usb tethering failed!"); </code></pre> <p>For disabling usb tethering, you just need to change the reflection method name "getTetherableIfaces" to "getTetheredIfaces", change "tether" to "untether".</p> <p>Please check.</p>
