HTTP代理不工作HTC渴望運行Android 2.2

Question

我使用HTTP代理使用下面的代碼：

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

能正常工作的幾款Android設備，所有運行Android 2.3及更高版本。然而，當我試圖在HTC慾望運行android 2.2.2時，我得到以下例外：

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

有沒有人見過這種行爲？謝謝！

正如在https://android-review.googlesource.com/#/c/15755/中指出的那樣，這看起來是一個在某些時候已經解決的錯誤，很可能在2.2之後解決。我找到了解決這一這裏http://code.google.com/p/android/issues/detail?id=2690，這是更換

HttpResponse response = httpclient.execute(httpRequest); 

與

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); 

顯然的問題是，該端口沒有被正確設置和的InetSocketAddress設置爲0。
