Hello,

You should Add your code after "Declare our new variable":

Declaring a (Button). Using the Button name (mExterminateButton) Using findById with properties (R.id.button1) mExterminateButton = (Button) findViewById(R.id.button1);

public class MainActivity extends Activity {

    protected Button mExterminateButton;

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

        // Declare our view variables
        mExterminateButton = (Button) findViewById(R.id.button1); // <- your code here
    }
}
