Free crop the image android

I want to crop the image with multiple paths like the below image:

.

So far, what I have implemented saves all drawn paths into an ArrayList, then I retrieve those cropped paths in another activity.

However, every path is adding the first drawn point.

Here's my code:

public boolean onTouch(View view, MotionEvent event) {

    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        points.clear();
        points2 = new ArrayList<Point>();
    }

    Point point = new Point();
    point.x = (int) event.getX();
    point.y = (int) event.getY();

    zoomPos.x = event.getX();
    zoomPos.y = event.getY();

    if (flgPathDraw) {
        zooming = true;
        if (bfirstpoint) {
            if (comparepoint(mfirstpoint, point)) {
                points.add(mfirstpoint);
                points2.add(mfirstpoint);
            } else {
                points.add(point);
                points2.add(point);
            }
        } else {
            points.add(point);
            points2.add(point);
        }
        if (!(bfirstpoint)) {
            mfirstpoint = point;
            bfirstpoint = true;
        }
    }

    invalidate();
    if (event.getAction() == MotionEvent.ACTION_UP) {
        mlastpoint = point;
        if (flgPathDraw) {
            if (points.size() > 12) {
                if (!comparepoint(mfirstpoint, mlastpoint)) {
                    zooming = false; 
                    points2.add(mfirstpoint);

                    addpaths.add(path);

                    invalidate();
                }
            }
        }

        if (points2!=null&&!(points2.isEmpty())) {
            pointlists.add(points2);
        }

    }

    return true;
}

//Croping code for drawn paths.

for (int j=0;j<CutPhotoView.pointlists.size();j++) {
    for (int i = 0; i <CutPhotoView.pointlists.get(j).size(); i++) {
        path.lineTo(CutPhotoView.pointlists.get(j).get(i).x, 
                    CutPhotoView.pointlists.get(j).get(i).y);
    }
    canvas.drawPath(path, paint);
}
