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
}
}
