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:
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. }
