Now I am working on an application.I want to show a progressbar until i get a true reply from called method.I used the following code.

 progressBar = new ProgressDialog(this);
      progressBar.setCancelable(true);
      progressBar.setMessage("Loading");
      progressBar.show();

new Thread(new Runnable() {


    @Override
    public void run() {
        // TODO Auto-generated method stub

        final boolean flag=  GetFixtureDetailsJsonFunction();

        if (flag==true) {
            try {
                Thread.sleep(2000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            progressBar.dismiss();
        }

    }
}).start();



protected boolean GetFixtureDetailsJsonFunction()
{ 
  //some code
  return true;
}

But I am getting the exception
