Android的WebView中设置代理编程方式在Android-L [英] Android WebView set proxy programmatically on Android-L

问题描述

所以<一个href=\"http://stackoverflow.com/questions/19979578/android-webview-set-proxy-programatically-kitkat\">this解决方案工作较昨日上涨至Android 4.4.4，不过，code停止在Android-L开发商preVIEW工作，没有任何人有一定的工作code为Android-L？或者，我如何可能会到code自己任何提示？

So this solution works up up to Android 4.4.4, however, the code ceases to work on Android-L developer preview, does anyone have some working code for Android-L? Or any tips on how I might get to the code myself?

这是当前的方法我使用奇巧（和作品）

This is the current method I use for KitKat (and works)

@TargetApi(Build.VERSION_CODES.KITKAT)
private static boolean setKitKatWebViewProxy(WebView webView, String host, int port) {
    Context appContext = webView.getContext().getApplicationContext();
    System.setProperty("http.proxyHost", host);
    System.setProperty("http.proxyPort", port + "");
    System.setProperty("https.proxyHost", host);
    System.setProperty("https.proxyPort", port + "");
    try {
        Class applictionCls = Class.forName(FinalVariables.APPLICATION_CANONICAL_NAME);
        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, null);
                    intent.putExtra("proxy", (Parcelable) proxyProperties);
                    /*********** optional, may be need in future *************/

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

感谢您！

推荐答案

删除的可选块我的<一个href=\"http://stackoverflow.com/questions/19979578/android-webview-set-proxy-programatically-kitkat\">$p$pvious为奇巧solusion 应该在Android L- preVIEW工作，因为ProxyProperties类不能在Android的L- preVIEW找到了。
因此，新的解决方案是：

Remove the the optional block of my previous solusion for kitkat should work on android L-preview, because the ProxyProperties class could not be found in android L-preview any more. So the new solution is:

public static void setLPreViewWebViewProxy(Context context, String host, int port) {
    System.setProperty("http.proxyHost", host);
    System.setProperty("http.proxyPort", port + "");
    try {
        Context appContext = context.getApplicationContext();
        Class applictionClass = Class.forName("android.app.Application");
        Field mLoadedApkField = applictionClass.getDeclaredField("mLoadedApk");
        mLoadedApkField.setAccessible(true);
        Object mloadedApk = mLoadedApkField.get(appContext);
        Class loadedApkClass = Class.forName("android.app.LoadedApk");
        Field mReceiversField = loadedApkClass.getDeclaredField("mReceivers");
        mReceiversField.setAccessible(true);
        ArrayMap receivers = (ArrayMap) mReceiversField.get(mloadedApk);
        for (Object receiverMap : receivers.values()) {
            for (Object receiver : ((ArrayMap) receiverMap).keySet()) {
                Class clazz = receiver.getClass();
                if (clazz.getName().contains("ProxyChangeListener")) {
                    Method onReceiveMethod = clazz.getDeclaredMethod("onReceive", Context.class, Intent.class);
                    Intent intent = new Intent(Proxy.PROXY_CHANGE_ACTION);
                    onReceiveMethod.invoke(receiver, appContext, intent);
                }
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}
