原文见http://android-developers.blogspot.com/2011/09/androids-http-clients.html 
这里小结下几点。 

1) apache httpclient比较稳定点,少BUG,但由于API的关系,扩展改造麻烦点, 
所以android team现在不鸟这东西了基本 

2) httpurlconnection比较轻便,灵活,易于扩展,在2。2前有个BUG, 
见http://code.google.com/p/android/issues/detail?id=2939 
  可以通过如下代码去解决: 
 

 

1. privatevoiddisableConnectionReuseIfNecessary() {    
2.  // HTTP connection reuse which was buggy pre-froyo    
3. if(Integer.parseInt(Build.VERSION.SDK) < Build.VERSION_CODES.FROYO) {        System.setProperty("http.keepAlive", "false");     
4. }  
5. }


3) 在Gingerbread中,httpurlconnection会增加对压缩报文头的处理,服务端可以用 


GZIP,详细见: 


  http://developer.android.com/reference/java/net/HttpURLConnection.html 

4) 对HTTPURLCONECTION中,在3。0后以及4。0中都进行了改善,比如对HTTPS的支持, 

在4。0中,还增加了对缓存的支持呢!比如下面的代码: 

  android 中对apache httpclient及h…_apache

1. privatevoidenableHttpResponseCache()   
2. {    
3.  try{  
4.        longhttpCacheSize = 10* 1024* 1024; // 10 MiB     
5.    File httpCacheDir = newFile(getCacheDir(), "http");      
6.    Class.forName("android.net.http.HttpResponseCache").getMethod("install", File.class, long.class.invoke(null, httpCacheDir, httpCacheSize);     
7. }   
8. catch  
9. (Exception httpResponseCacheNotAvailable) {    
10.  }  
11. }
