Android主屏幕小部件的最大高度和宽度

Question

Is there a possible way to get the size of device's grid? (4x4 or 5x5). With the code below, I can only get the dimension of the full screen. I've attached an image file for clarification.

Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
int width = size.x;
int height = size.y;

Answer 1

I've had an appWidget that was 1x1 cell in size. I set it to 72dp x 72dp, and it was working fine.. But it seems like Google changed the widget dimension sizing formula from

(cells * 74) - 2

to

(cells * 70) - 30

So now the default size of my widget has to be 40dp x 40dp..
