Android Send Post Data To Server

Question

This is a possible duplicate of Sending POST data in Android

I used this code to send post data to server using android

public void postData() {
        // Create a new HttpClient and Post Header
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://www.mysite.com/android.php");

        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("id", "12345"));
            nameValuePairs.add(new BasicNameValuePair("stringdata", "Hi"));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);

        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
        } catch (IOException e) {
            // TODO Auto-generated catch block
        }
    }

But when I run this app it shows this error

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.senddata/com.example.senddata.MainActivity}: android.os.NetworkOnMainThreadException

Whats problem? Can anyone help?

Try using the below code inside your mainactivityactivity below setContentView() to avoid networkOnmainThread exception..

if (android.os.Build.VERSION.SDK_INT > 9) {
                StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
                StrictMode.setThreadPolicy(policy);
            }

But, doing heavy operation inside background thread using AsyncTask without blocking main thread would be great!

And also refer this link...

Call the postData using an asyntask, in the doInBackground of asyntask. Do not call it from the mainThread

You can't do Networking related tasks on Main Thread use AsyncTask Class instead
