Main thread issue in Android | Async class demo in Android | Background Thread

Hello Friends,
Today I am going to share simple code for Async class in Android. At the time of development sometime we catch Main Thread exception for this we should use Async  or Background Thread. Hope my blog will help you-

import android.app.Activity;

import android.app.ProgressDialog;

import android.os.AsyncTask;

import android.os.Bundle;

public class AsyncClassTest extends Activity {

       public void onCreate(Bundle savedInstanceState) {

              super.onCreate(savedInstanceState);

              setContentView(R.layout.screen_sign_up);

              /**

               * do what you want here Like- get textbox, imageview id's etc

               */

              // Call Async Class

              new getProfileimage().execute();

       }

       public class getProfileimage extends AsyncTask<String, Void, String> {

              ProgressDialog pd = null;

              @Override

              protected void onPreExecute() {

                     pd = ProgressDialog.show(AsyncClassTest.this, "Please wait",

                                  "Loading please wait..", true);

                     pd.setCancelable(true);

              }

              @Override

              protected String doInBackground(String... params) {

                     /**

                      * Do what you want here in background Thread Like- call any

                      * web service, get data from server and set into Listview etc.

                      */

                     return null;

              }

              @Override

              protected void onPostExecute(String result) {

                     pd.dismiss();

                     /**

                      * 1)dismiss progress dialog 2)do main thread task here like-

                      *  set view, make toast etc.

                      */

              }

       }

}

Note- 

1)See comments for help.

2)Don't do any View related task inside background thread.

3)For any help please comment on my blog.

Thanks,
