How to increase size of center button icon.

[Aastha-dev]

I have added icon with size 290*230 pixel in drawable - xhdpi then also size has not been increased. I had also added this property in xml app:space_item_icon_only_size="40dp" which increase other item size but does not increase center button size.

instead of using small drawable file use a big size drawable file.
