Let's start with the Apple class by adding the required import statements and the member variables. Add the code and study it, and then we will discuss it:
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.graphics.Point;
import java.util.Random;
class Apple {
// The location of the apple on the grid
// Not in pixels
private Point mLocation = new Point();
// The range of values we can choose from
// to spawn an apple
private Point mSpawnRange;
private int mSize;
// An image to represent the apple
private Bitmap mBitmapApple;
}The Apple class has a Point object that we will use to store the horizontal and vertical location of the apple. Note that this will be a position on our virtual grid, and not a specific pixel position.
There is a second Point variable called mSpawnRange as well that will eventually hold...
