Answer 1

Based on @Sakthi 's code, but add scaling :)

        Rect rect = new Rect(0,0,canvas.getWidth(), canvas.getHeight());
        Matrix matrix = new Matrix();
        matrix.postTranslate(-bitmap.getWidth()/2, -bitmap.getHeight()/2);
        matrix.postScale(
                ((float)rect.width()) / bitmap.getWidth(),
                ((float)rect.height()) / bitmap.getHeight());
        matrix.postRotate(180);
        matrix.postTranslate(rect.exactCenterX(), rect.exactCenterY());
        canvas.drawBitmap(bitmap, matrix, null);
