在官方blog中,android工程师谈到了如何去选择apache client和httpurlconnection的问题:
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:
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:
最后的建议,Gingerbread后的版本,都建议用httpurlconnection,获得更高的性能

可以通过如下代码去解决:
- private void disableConnectionReuseIfNecessary() {
- // HTTP connection reuse which was buggy pre-froyo
- if (Integer.parseInt(Build.VERSION.SDK) < Build.VERSION_CODES.FROYO) { System.setProperty("http.keepAlive", "false");
- }
- }
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:
- private void enableHttpResponseCache()
- {
- try {
- long httpCacheSize = 10 * 1024 * 1024; // 10 MiB
- File httpCacheDir = new File(getCacheDir(), "http");
- Class.forName("android.net.http.HttpResponseCache").getMethod("install", File.class, long.class.invoke(null, httpCacheDir, httpCacheSize);
- }
- catch
- (Exception httpResponseCacheNotAvailable) {
- }
- }

---------------原文-------------------------
Most network-connected Android apps use HTTP to send and receive data. Android includes two HTTP clients: HttpURLConnection and Apache HttpClient. Both support HTTPS, streaming uploads and downloads, configurable timeouts, IPv6, and connection pooling. We recommend using HttpURLConnection for applications targeted at Gingerbread and higher. For more discussion of this topic, see the blog post Android's HTTP Clients.
