I'm getting this when I click my login button and I have no idea why, I don't know why it says Hello in the error and I searched my whole project and can't find the occurrence of "Hello". Is there another cause for this error?
public class Login extends Activity implements OnClickListener {
private EditText user, pass;

// JSON parser class
JSONParser jsonParser = new JSONParser();

private static final String TAG_SUCCESS = "success";
private static final String TAG_MESSAGE = "message";
