Question

我正在使用this code在Android上为我的WebView设置代理，但它运行良好。我修改了代码以使用排除列表。在使用android.net.ProxyProperties的设备上，我正在传递一个排除列表，例如＆＃34; .google.com，.bing.com＆＃34;在使用系统属性的设备上，我正在传递＆＃34; .google.com | .bing.com＆＃34;。它在ICS和Lollipop上都运行良好，但我不能让它在KitKat上工作。我没有4.2 / 4.3设备可以测试，但我稍后会在模拟器上尝试它，无论他们的代码与设置代理的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;
    }

有什么可能出错的想法吗？

感谢。

找出问题所在。我不得不评论一个甚至不需要的部分。评论的部分是：

/*********** 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);
/*********** optional, may be need in future *************/

如何在KitKat上以编程方式配置的代理上设置排除列表？
