apache http client vs urlconnection

Google has deprecated HttpClient 

Choose an HTTP Client

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.
