currently using string.replace("-",""); removing '-' contact number.

you can use phonenumberutils.stripseparators(string) (available in api 1+).

or can use regular expression‌​:

filternum = filternum.replaceall("[^0-9]+", ""); 

— remove characters not in range 0...9. think easier. here's the documentation.
