我想在我的设备上启动代理服务器。它可以在所有网络上打开并在wifi和蜂窝连接期间工作。我使用this项目作为示例，它工作不稳定。在客户端应用程序中，我使用此代码连接到webview中的代理：
public class ProxySettings {
static final int PROXY_CHANGED = 193;
private static Object getDeclaredField(Object obj, String name)
throws SecurityException, NoSuchFieldException,
IllegalArgumentException, IllegalAccessException {
Field f = obj.getClass().getDeclaredField(name);
f.setAccessible(true);
Object out = f.get(obj);
return out;
}
public static Object getRequestQueue(Context ctx) throws Exception {
Object ret = null;
Class networkClass = Class.forName("android.webkit.Network");
if (networkClass != null) {
Object networkObj = invokeMethod(networkClass, "getInstance",
new Object[] { ctx },
Context.class);
if (networkObj != null) {
ret = getDeclaredField(networkObj, "mRequestQueue");
}
}
return ret;
}
private static Object invokeMethod(Object object, String methodName,
Object[] params, Class... types) throws Exception {
Object out = null;
Class c = object instanceof Class ? (Class) object :
object.getClass();
if (types != null) {
Method method = c.getMethod(methodName, types);
out = method.invoke(object, params);
} else {
Method method = c.getMethod(methodName);
out = method.invoke(object);
}
return out;
}
public static void resetProxy(Context ctx) throws Exception {
Object requestQueueObject = getRequestQueue(ctx);
if (requestQueueObject != null) {
setDeclaredField(requestQueueObject, "mProxyHost", null);
}
}
private static void setDeclaredField(Object obj, String name, Object
value) throws SecurityException, NoSuchFieldException,
IllegalArgumentException, IllegalAccessException {
Field f = obj.getClass().getDeclaredField(name);
f.setAccessible(true);
f.set(obj, value);
}
public static boolean setProxy(Context ctx, String host, int port) {
boolean ret = false;
setSystemProperties(host, port);
try {
Log.e("MEGATAG", "ProxySettings.setProxy try");
if (Build.VERSION.SDK_INT < 14) {
Log.e("MEGATAG", "ProxySettings.setProxy try if");
Object requestQueueObject = getRequestQueue(ctx);
if (requestQueueObject != null) {
HttpHost httpHost = new HttpHost(host, port, "http");
setDeclaredField(requestQueueObject, "mProxyHost",
httpHost);
ret = true;
}
} else {
ret = setICSProxy(host, port);
}
} catch (Exception e) {
}
return ret;
}
private static boolean setICSProxy(String host, int port) throws
ClassNotFoundException, NoSuchMethodException,
IllegalArgumentException, InstantiationException,
IllegalAccessException, InvocationTargetException {
Log.e("MEGATAG", "ProxySettings.setICSProxy");
Class webViewCoreClass =
Class.forName("android.webkit.WebViewCore");
Class proxyPropertiesClass =
Class.forName("android.net.ProxyProperties");
if (webViewCoreClass != null && proxyPropertiesClass != null){
Method m = webViewCoreClass
.getDeclaredMethod("sendStaticMessage", Integer
.TYPE,Object.class);
Constructor c = proxyPropertiesClass
.getConstructor(String.class, Integer.TYPE,String.class);
m.setAccessible(true);
c.setAccessible(true);
Object properties = c.newInstance(host, port, null);
m.invoke(null, PROXY_CHANGED, properties);
Log.e("MEGATAG", "setICSProxy true");
return true;
}
Log.e("MEGATAG", "ProxySettings.setICSProxy else -> false");
return false;
}
private static void setSystemProperties(String host, int port) {
Log.e("MEGATAG", "ProxySettings.setSystemProperties");
System.setProperty("http.proxyHost", host);
System.setProperty("http.proxyPort", port + "");
System.setProperty("https.proxyHost", host);
System.setProperty("https.proxyPort", port + "");
}
}
如果我认为它工作不稳定，因为端口阻塞，当我连接时。我添加了方法，关闭我的套接字连接以取消阻止端口，它不起作用。也许任何人都有这个问题并解决了它，并且可以帮助我。
