thank time

i dont know thought static , cannot changed on run time.

you create work around here

first create class , add together public static string that

e.g

public class stringgen { public static string username public static string password }

set info perhaps log in

stringgen.username = *yourstring*

and phone call on app (activities , etc)

string myusername = stringgen.username

cheers
