12,206 PointsWhy is this question in the course right off the start?
I just started the "Build an Interactive Story App" course and I watched the first video. I then moved on to the second step and it was this question:
"Initialize the member variable mExterminateButton using the findViewById() method. The ID for the button is button1. Don't forget to cast the generic View returned by the method!"
Why is this a part of the course right off the start? Was it a test to see if the user watched the "How to make a simple app" course? Is it an error? I answered it right, but it seemed kind of weird.
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
}
}

Courses Plus Student 94,610 PointsHi Michael,
In the "Beginner Android Development" track, this course is listed after "Build a Simple Android App".
I don't know if that course was listed as a prerequisite for this course but I think the challenge is assuming a certain level of prerequisite knowledge.
