Android - Split Drawable

Question

I am attempting to split an image into pieces, lets say for example 16 chunks (4x4).

I have found so many examples with java, but Android does not have BufferedImage

I think you need this

void createImageArrays()
{
    Bitmap bMap = BitmapFactory.decodeResource(getResources(), image);
    Bitmap bMapScaled = Bitmap.createScaledBitmap(bMap, 240, 240, true);

    bitmapsArray[0] = Bitmap.createBitmap(bMapScaled, 0, 0, 80, 80);
    bitmapsArray[1] = Bitmap.createBitmap(bMapScaled, 80, 0, 80, 80);
    bitmapsArray[2] = Bitmap.createBitmap(bMapScaled, 160, 0, 80, 80);
    bitmapsArray[3] = Bitmap.createBitmap(bMapScaled, 0, 80, 80, 80);
    bitmapsArray[4] = Bitmap.createBitmap(bMapScaled, 80, 80, 80, 80);
    bitmapsArray[5] = Bitmap.createBitmap(bMapScaled, 160, 80, 80, 80);
    bitmapsArray[6] = Bitmap.createBitmap(bMapScaled, 0, 160, 80, 80);
    bitmapsArray[7] = Bitmap.createBitmap(bMapScaled, 80, 160, 80, 80);
    bitmapsArray[8] = Bitmap.createBitmap(bMapScaled, 160, 160, 80, 80);

}

The original image is 240x240 and I divided it into 9 pieces of 80x80

BufferedImage in Java SE is like a Bitmap in Android. Drawable is just an interface that tells you that something is drawable. It can be a bitmap, shape, color, etc.
