MainActivity.java

public class MainActivity extends Activity {

    Button submit;
    ProgressDialog pDialog;
    ImageView imageView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        submit = (Button) findViewById(R.id.SUBMIT_BUTTON_ID);
        imageView = (ImageView) findViewById(R.id.imageView1);
        submit.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                new MainTest().execute();


            }
        });
    }

            s = s.append(sResponse);
        }
    }

    public class MainTest extends AsyncTask<String, Integer, String> {

        @Override
        protected void onPreExecute() {
            pDialog = new ProgressDialog(MainActivity.this);
            pDialog.setMessage("Loading..");
            pDialog.setIndeterminate(true);
            pDialog.setCancelable(false);
            pDialog.show();
        }

        @Override
        protected String doInBackground(String... params) {

            try {
                postImageData();
            } catch (IOException e) {

        }

    }

}
