android中实现禁掉有线网络

 1.首先初始化mINetworkManagementServiceProxy 

// INetworkManagementService mNwService;
Object mINetworkManagementServiceProxy;public void init() {// IBinder b = ServiceManager.getService(Context.NETWORKMANAGEMENT_SERVICE);// mNwService = INetworkManagementService.Stub.asInterface(b);try {Class<?> smClass = Class.forName("android.os.ServiceManager");Method getService = smClass.getMethod("getService", new Class[]{String.class});getService.setAccessible(true);IBinder networkManagementBinder = (IBinder) getService.invoke(null, new Object[]{"network_management"});Class<?> iNMSClass = Class.forName("android.os.INetworkManagementService$Stub");Method asInterface = iNMSClass.getMethod("asInterface", new Class[]{IBinder.class});asInterface.setAccessible(true);mINetworkManagementServiceProxy = asInterface.invoke(null, new Object[]{networkManagementBinder});Log.d("Debug", "init: mINetworkManagementServiceProxy = " + mINetworkManagementServiceProxy);} catch (Throwable e) {Log.d("Debug", "init: get INetworkManagementServiceProxy failed !!! ");}
}

 2.初始化完成后，打开关闭eth0

//打开有线网
private void openEth0() {try {Method setInterfaceUp = mINetworkManagementServiceProxy.getClass().getMethod("setInterfaceUp", new Class[]{String.class});setInterfaceUp.setAccessible(true);setInterfaceUp.invoke(mINetworkManagementServiceProxy, "eth0");} catch (Throwable e) {Log.d("Debug", "openEth0: failed !!! ");}
}

//禁用有线网
private void closeEth0() {try {Method setInterfaceDown = mINetworkManagementServiceProxy.getClass().getMethod("setInterfaceDown", new Class[]{String.class});setInterfaceDown.setAccessible(true);setInterfaceDown.invoke(mINetworkManagementServiceProxy, "eth0");} catch (Throwable e) {Log.d("Debug", "closeEth0: failed !!! ");}
}

如果报错，抛出安全异常的话，需要添加权限：（我没有添加也是可以的）

<uses-permission android:name="android.permission.CONNECTIVITY_INTERNAL" />
<uses-permission android:name="android.permission.NETWORK_STACK" />
<uses-permission android:name="android.permission.MAINLINE_NETWORK_STACK" />

可能只有system app可以使用，但不确定，待验证！
