okhttp

Asynchronous: can run, the bottom package of thread
synchronization: the child must be placed in the thread run, the interface does not require rewriting
get method
1, okhttp client
OkHttpClient = new new OkHttpClient Client ();
2, the request object Request
Request build Request.Builder new new = () URL (URL) .get () Build ();..
. 3, Response result objects
the Response Response = client.newCall (Build) .execute ();
. 4, the results obtained
String json = response.body () .string ();
POST method
formBody discharge parameters
. formBody builder = new FormBody.Builder () add ( key, value) .build ();
Call Call = client.newCall (Request);
rewriting the Callback ()

volley for high frequency small data downloads
request = new StringRequest (com.android.volley.Request.Method.GET, URL, monitor the results, error monitor) StringRequest;
RequestQueue requestQueue = Volley.newRequestQueue (context); // added to the queue
requestQueue.add (request); // add to the request queue
requestQueue.start (); // start queue

post
override the getParams ()
to create the HashMap
PUT parameter and corresponding value
