HttpGet throws an exception, does not understand! Ask for guidance ~

============ Problem Description ============

Want to use the database to do a login authentication function, server-side response is normal, JSON packet {"ret": 1, "num": 123}
RET is the status value when logging in normally, NUM is number: 123
URL is 192.168.1.3:8080/web/getactinfo
Params:num=123
Through the logcat found in the HttpGet throws an exception, but do not understand!! Pain for an afternoon to ask for a nudge!

public string httpget (string url, string params) throws Exception
{
String response = null;
if (Null!=params&&!params.equals (""))
{

URL + = "?" + params;
}

int timeoutconnection = 8000;
int timeoutsocket = 10000;
Httpparams httpparameters = new Basichttpparams ();//Set the timeout in milliseconds until a connection is established.
Httpconnectionparams.setconnectiontimeout (Httpparameters, timeoutconnection);//Set The default socket timeout (so_ TIMEOUT)//in milliseconds which are the timeout for waiting for data.
Httpconnectionparams.setsotimeout (Httpparameters, Timeoutsocket);

HttpClient HttpClient = new Defaulthttpclient (httpparameters);
HttpGet httpget = new HttpGet (URL);
Try
{
HttpResponse HttpResponse = Httpclient.execute (HttpGet);
int statusCode = Httpresponse.getstatusline (). Getstatuscode ();
if (StatusCode = = HTTPSTATUS.SC_OK)//SC_OK = 200
{
Response = entityutils.tostring (Httpresponse.getentity ());
}
Else
{
Response = "Status Code" +STATUSCODE;
}
} catch (Exception e)
{
throw new Exception (e);
}

Networkonmainthreadexception
Network requests cannot be placed on the main thread
Open a thread to get the data

============ Solution 2============

The main thread can not do network requests, you put these network operations in the new line thread or asynchronous task
