如何在 KitKat 上以编程方式配置的代理上设置排除列表？

Question

我正在使用this code 为我在 Android 上的 WebView 设置代理，它运行良好。我已修改代码以使用排除列表。在使用 android.net.ProxyProperties 的设备上，我传递了一个排除列表，例如“.google.com,.bing.com”，在使用系统属性的设备上，我传递了“.google.com| .bing.com”。在 ICS 和 Lollipop 上一切正常，但我无法让它在 KitKat 上工作。我没有要测试的 4.2/4.3 设备，但我稍后会在模拟器上尝试，无论哪种方式，它们的代码都与设置代理的 ICS 相同。

我在 KitKat 上设置的代理代码如下所示：

private static boolean setProxyKK(WebView webView, String host, int port, String applicationClassName) {
        Log.d(LOG_TAG, "Setting proxy with 4.4-4.4.4 API.");

        Context appContext = webView.getContext().getApplicationContext();
     System.setProperty("http.proxyHost", host);
    System.setProperty("http.proxyPort", port + "");
    System.setProperty("http.nonProxyHosts", "*.google.com|*.bing.com");
        try {
            Class applictionCls = Class.forName(applicationClassName);
            Field loadedApkField = applictionCls.getField("mLoadedApk");
            loadedApkField.setAccessible(true);
            Object loadedApk = loadedApkField.get(appContext);
            Class loadedApkCls = Class.forName("android.app.LoadedApk");
            Field receiversField = loadedApkCls.getDeclaredField("mReceivers");
            receiversField.setAccessible(true);
            ArrayMap receivers = (ArrayMap) receiversField.get(loadedApk);
            for (Object receiverMap : receivers.values()) {
                for (Object rec : ((ArrayMap) receiverMap).keySet()) {
                    Class clazz = rec.getClass();
                    if (clazz.getName().contains("ProxyChangeListener")) {
                        Method onReceiveMethod = clazz.getDeclaredMethod("onReceive", Context.class, Intent.class);
                        Intent intent = new Intent(Proxy.PROXY_CHANGE_ACTION);

                        /*********** optional, may be need in future *************/
                        final String CLASS_NAME = "android.net.ProxyProperties";
                        Class cls = Class.forName(CLASS_NAME);
                        Constructor constructor = cls.getConstructor(String.class, Integer.TYPE, String.class);
                        constructor.setAccessible(true);
                        Object proxyProperties = constructor.newInstance(host, port, ".google.com,.bing.com");
                        intent.putExtra("proxy", (Parcelable) proxyProperties);
                        /*********** optional, may be need in future *************/

                        onReceiveMethod.invoke(rec, appContext, intent);
                    }
                }
            }

            Log.d(LOG_TAG, "Setting proxy with >= 4.4 API successful!");
            return true;
        } catch (ClassNotFoundException e) {
            StringWriter sw = new StringWriter();
            e.printStackTrace(new PrintWriter(sw));
            String exceptionAsString = sw.toString();
            Log.v(LOG_TAG, e.getMessage());
            Log.v(LOG_TAG, exceptionAsString);
        } catch (NoSuchFieldException e) {
            StringWriter sw = new StringWriter();
            e.printStackTrace(new PrintWriter(sw));
            String exceptionAsString = sw.toString();
            Log.v(LOG_TAG, e.getMessage());
            Log.v(LOG_TAG, exceptionAsString);
        } catch (IllegalAccessException e) {
            StringWriter sw = new StringWriter();
            e.printStackTrace(new PrintWriter(sw));
            String exceptionAsString = sw.toString();
            Log.v(LOG_TAG, e.getMessage());
            Log.v(LOG_TAG, exceptionAsString);
        } catch (IllegalArgumentException e) {
            StringWriter sw = new StringWriter();
            e.printStackTrace(new PrintWriter(sw));
            String exceptionAsString = sw.toString();
            Log.v(LOG_TAG, e.getMessage());
            Log.v(LOG_TAG, exceptionAsString);
        } catch (NoSuchMethodException e) {
            StringWriter sw = new StringWriter();
            e.printStackTrace(new PrintWriter(sw));
            String exceptionAsString = sw.toString();
            Log.v(LOG_TAG, e.getMessage());
            Log.v(LOG_TAG, exceptionAsString);
        } catch (InvocationTargetException e) {
            StringWriter sw = new StringWriter();
            e.printStackTrace(new PrintWriter(sw));
            String exceptionAsString = sw.toString();
            Log.v(LOG_TAG, e.getMessage());
            Log.v(LOG_TAG, exceptionAsString);
        } catch (InstantiationException e) {
            StringWriter sw = new StringWriter();
            e.printStackTrace(new PrintWriter(sw));
            String exceptionAsString = sw.toString();
            Log.v(LOG_TAG, e.getMessage());
            Log.v(LOG_TAG, exceptionAsString);
        }
        return false;
    }

知道它可能有什么问题吗？

谢谢。

解决了这个问题。我不得不注释掉一个甚至不需要的部分。要注释掉的部分是：

/*********** optional, may be need in future *************/
                    final String CLASS_NAME = "android.net.ProxyProperties";
                    Class cls = Class.forName(CLASS_NAME);
                    Constructor constructor = cls.getConstructor(String.class, Integer.TYPE, String.class);
                    constructor.setAccessible(true);
                    Object proxyProperties = constructor.newInstance(host, port, ".google.com,.bing.com");
                    intent.putExtra("proxy", (Parcelable) proxyProperties);
