You should assign your variable inside your onCreate() method after you have called setContentView() and you added an extra full stop (period) by mistake after the casting to a button which is removed in the code below.
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
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);
}
}
Hope this helps Daniel
