    private static final int LEFT= 1;
    private static final int TOP= 2;
    private static final int RIGHT= 3;
    private static final int BOTTOM= 4;

    private int imageScaledWidth,imageScaledHeight;
    // Adding parent class constructors   
    public CropView(Context context) {
        super(context);
        initCropView();
    }

    public CropView(Context context, AttributeSet attrs) {
        super(context, attrs, 0);
        initCropView();
    } …
