I have this code which sets a proxy on a WebView on Android 4.4.x and it used to work great but after the 4.4.4 it stopped working. It still works on 4.4.2 and it used to work on 4.4.3. Anyone have any idea of how to fix it? Thanks.
Code:
private static boolean setProxyKK(WebView webView, String host, int port, String applicationClassName) {
Log.d(LOG_TAG, "Setting proxy with >= 4.4 API.");
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(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, null);
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) {

Log.v(LOG_TAG, exceptionAsString);

e.printStackTrace(new PrintWriter(sw));
String exceptionAsString = sw.toString();
Log.v(LOG_TAG, e.getMessage());
Log.v(LOG_TAG, exceptionAsString);

e.printStackTrace(new PrintWriter(sw));
String exceptionAsString = sw.toString();
Log.v(LOG_TAG, e.getMessage());
Log.v(LOG_TAG, exceptionAsString);

return false;
