一个简单的Demo，从聚合数据申请手机号码归属地数据接口；

在EditText中输入待查询号码，获取号码后在子线程中使用HttpUrlconnection获取JSON数据，之后进行解析；

## 认识Http协议 ##

Android中发送http网络请求是很常见的，要有GET请求和POST请求。一个完整的http请求需要经历两个过程：客户端发送请求到服务器，然后服务器将结果返回给客户端，如下图所示：

*  客户端->服务器   
    客户端向服务器发送请求主要包含以下信息：请求的Url地址、请求头以及可选的请求体，打开百度首页，客户端向服务器发送的信息如

URLConnection是个 [抽象类][Link 1]，它有两个直接子类分别是HttpURLConnection和JarURLConnection。另外一个重要的类是URL，通常URL可以通过传给 [构造器][Link 2]一个String类型的参数来生成一个指向特定地址的URL实例。

每个 HttpURLConnection 实例都可用于生成单个请求，但是其他实例可以透明地共享连接到 HTTP 服务器的基础网络。请求后在 HttpURLConnection 的 InputStream 或 OutputStream 上调用 close() 方法可以释放与此实例关联的网络资源，但对共享的 [持久连接][Link 3]没有任何影响。如果在调用 disconnect() 时持久连接空闲，则可能关闭基础 [套接字][Link 4]。
