When specifying the width and height of your scaled Bitmap, is the method asking for pixels or density-independent pixels?
I have a 240dp device and when scaling an image to 240x240, the image is barely half the screen size. I was expecting it to be full screen. Does this mean the method uses pixels?

You can do a check when you want to return the BitMap look to see if the ArrayList of Paths is bigger than 0 and return the BitMap if so, or else return null.
A bitmap (or raster graphic) is a digital image composed of a matrix of dots. When viewed at 100%, each dot corresponds to an individual pixel on a display. In a standard bitmap image, each dot can be assigned a different color. In this instance we will simply create a Bitmap directly: Bitmap b = Bitmap.
A bitmap is a mapping from one system such as integers to bits. It is also known as bitmap index or a bit array. The memory is divided into units for bitmap. These units may range from a few bytes to several kilobytes. Each memory unit is associated with a bit in the bitmap.
Yes, it uses px. You can obtain the size of the screen, and call createScaledBitmap(screenWidth ... )
