Malfunctioning in Lollipop but Functioning in KitKat

Question

I'm trying to give an EndGame response to players based on their performance on a game.

I access the method "onDraw" from MainActivity to display the message.

It works like a charm in Kitkat but on lollipop it somehow crashes.

Here are the codes:

In MainActivity

if (rec.getGameOver()) {
            saveScore(rec.getScore());
            rec.onDraw(rec.getCanvas());
        }

In Game class extends view

 if (score > value) {
            paint.setColor(Color.parseColor("#000000"));
            paint.setTextSize((int) (value));
            canvas1.drawText("Nice!", 0, (int) (value), paint);
            canvas1.drawText("Your got" + score, 0, (int) (value), paint);
        } else {
            paint.setColor(Color.parseColor("#000000"));
            paint.setTextSize((int) (value);
            canvas1.drawText("Try Again?!", 0, (int) (value), paint);
            canvas1.drawText("Your got" + score, 0, (int) (value), paint);
        }
        invalidate();

Every variable was already defined before use.

edit: here is the error
