ANDROID - after click button, go to landscape page

Question

I have a problem....

First, I go to main page. After I click MASUK button, I hope I can go to BOARD VIEW which have landscape orientation. But I got error.

public class MainActivity extends Activity {
Button masuk;

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

    masuk = (Button) findViewById(R.id.button_masuk);
    masukClicked();
 }

 void masukClicked() {
    masuk.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            Intent intent = new Intent(MainActivity.this, Board.class);
            startActivity(intent);
        }
    });
 }
}

BOARD VIEW in this class

public class Board extends Activity{

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