Solution of HttpURLConnection throw exception in Android

HTTP URL link, an error occurs, mainly because in the main UI thread, the Networkonmainthreadexception exception is thrown by using network invoke (network call).

Version: API level above 11.

You can avoid this situation by using a simple thread that invokes the program in the background (asynctask);

Otherwise, the exception is thrown at the Getresponsecode () function.

Android api:http://developer.android.com/reference/android/os/asynctask.html.

Code:

String quakefeed = getString (r.string.quake_feed);  
url = new URL (quakefeed);  
      
URLConnection connection;  
Connection = Url.openconnection ();  
      
HttpURLConnection httpconnection = (httpurlconnection) connection;  
int responsecode = Httpconnection.getresponsecode ();

Modify:

Thread t = new Thread (new Runnable () {  
    @Override public
    void Run () {  
        refreshearthquakes ();  
    }  
});  
      
T.start ();

That is, put a program that requires network calls (network call) into threads to execute.
