Try this

    public class Login extends Activity {
 /** Called when the activity is first created. */


 private static final String SOAP_ACTION = "http://tempuri.org/LoginUser";
 private static final String METHOD_NAME = "LoginUser";
 private static final String NAMESPACE = "http://tempuri.org/";
 private static final String URL = "http://";
 private static final String TAG = "HELLO";

 @Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);
Button signin = (Button) findViewById(R.id.regsubmitbtn);



       signin.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {

    new StartLoginAsyncTask(yourclass.this).execute();


    }
 });
  }


   private class LoginTask extends AsyncTask<Void, Void, Boolean> {
   private final ProgressDialog dialog = new ProgressDialog(YourClass.this);

   protected void onPreExecute() {
     this.dialog.setMessage("Logging in...");
     this.dialog.show();
  }

   protected Boolean doInBackground(final Void unused) {
     return Main.this.login(); //don't interact with the ui!
  }

        protected void onPostExecute(final Boolean result) {
       if (this.dialog.isShowing()) {
            this.dialog.dismiss();
          }
             if (result.booleanValue()) {
             //also show register success dialog
         }
      }
           }




            private String doLogin() {
                EditText etxt_user = (EditText)findViewById(R.id.emaileditlog);
                String email_id = etxt_user.getText().toString();
                EditText etxt_password = (EditText)findViewById(R.id.pwdeditlog);
                String password = etxt_password.getText().toString();
                           SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
