在安卓上网络请求有两种方式，一种是java自带的HttpURLConnection, 一种是Apache的Http Clinet, 但是要选择两方式比较好呢？

Which client is best?
Apache HTTP client has fewer bugs on Eclair and Froyo. It is the best choice for these releases.


For Gingerbread and better, HttpURLConnection is the best choice. Its simple API and small size makes it great fit for Android. Transparent compression and response caching reduce network use, improve speed and save battery. New applications should use HttpURLConnection; it is where we will be spending our energy going forward.

            if (Build.VERSION.SDK_INT >= 9) {
                stack = new HurlStack();-->HttpURLConnection 
            } else {
                // Prior to Gingerbread, HttpUrlConnection was unreliable.
                // See: http://android-developers.blogspot.com/2011/09/androids-http-clients.html
                stack = new HttpClientStack(AndroidHttpClient.newInstance(userAgent)); -->Apache Http client
            }
