HTTP代理无法运行HTC android 2.2

Question

我正在使用以下代码使用HTTP代理：

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

这在几个运行android 2.3及更高版本的android设备上都可以正常工作。 但是，当我在运行android 2.2.2的HTC欲望上尝试此操作时，出现以下异常：

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

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

有人见过这种行为吗？ 谢谢！

Answer 1

如https://android-review.googlesource.com/#/c/15755/中所述 ，这似乎是在某个时间点已解决的错误，很可能是在2.2之后。 我在http://code.google.com/p/android/issues/detail?id=2690处找到了解决方法，该方法可以代替

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);

显然问题是端口设置不正确，并且在InetSocketAddress中设置为0。
