Question

我使用以下代码使用HTTP代理：

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

这适用于几个Android设备，都运行Android 2.3及更高版本。但是，当我尝试运行Android 2.2.2的HTC欲望时，我得到以下异常：

java.lang.IllegalArgumentException
java.net.InetSocketAddress.<init>(InetSocketAddress.java:98)

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

之前有没有人见过这种行为？谢谢！

如https://android-review.googlesource.com/#/c/15755/所述，这似乎是一个在某些时候得到解决的错误，很可能是在2.2之后。我在这里找到了解决方法http://code.google.com/p/android/issues/detail?id=2690，即替换

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);

显然问题是端口没有正确设置，并且在InetSocketAddress中设置为0.

HTTP代理不能在HTC上运行android 2.2
