public class HellonumberActivity extends Activity {

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        Button exit = (Button)findViewById(R.id.btnexit);

        exit.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {

                                                })

                                                .setNegativeButton("No",

                                                                                new DialogInterface.OnClickListener() {

                                                                                                public void onClick(DialogInterface dialog, int arg1) {
