HTTP代理不工作HTC渴望运行Android 2.2

Question

我使用HTTP代理使用下面的代码：

DefaultHttpClient client = new DefaultHttpClient(); 
HttpHost proxy = new HttpHost(proxyHost, proxyPort, "http"); 
client.getParams().setParameter(ConnRoutePNames.DEFAULT_PROXY, proxy); 

能正常工作的几款Android设备，所有运行Android 2.3及更高版本。然而，当我试图在HTC欲望运行android 2.2.2时，我得到以下例外：

java.lang.IllegalArgumentException

java.net.InetSocketAddress.<init>(InetSocketAddress.java:89)

org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:487) 
org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:465) 

有没有人见过这种行为？谢谢！

正如在https://android-review.googlesource.com/#/c/15755/中指出的那样，这看起来是一个在某些时候已经解决的错误，很可能在2.2之后解决。我找到了解决这一这里http://code.google.com/p/android/issues/detail?id=2690，这是更换

HttpResponse response = httpclient.execute(httpRequest); 

与

int port = httpRequest.getURI().toString().startsWith("https") ? 443 : 80; 
HttpHost host = new HttpHost(httpRequest.getURI().getHost(), port, httpRequest.getURI().getScheme()); 
HttpResponse response = httpclient.execute(host, httpRequest); 

显然的问题是，该端口没有被正确设置和的InetSocketAddress设置为0。
