Problems about GUI fontsize

I declared 2 GUIstyles in one script, like this:

var TextStyle1 = new GUIStyle();
var TextStyle2 = new GUIStyle();

In the inspect I set the fontsize of “TextStyle1” to be 40,
and, the fontsize of “TextStyle2” to be 30,
Now here is the question:
If i just run it in unity, the different fontsizes were set correctly,
but if i “build and run” it on an andriod pad,
the text showed on the pad screen were the same small, just like I didn’t set it before.

Can anyone tell me what happened??? Thanks!

FWIW…

note the selected answer in green here …

we totally gave up and just made the change to GlyphDesigner/2DTK. It is incredibly easier.
