shiv,

you have fetched values in variable "appno" set values variable "countrycode" instead of "appno".

in displaydetails.java, trying fetch the variable "appln_no" incorrect.

if @ code seems want pass appno value activity should keep this:

listviewdetails.java objintent.putextra("countrycode", appno);

displaydetails.java

int appno=intentobj.getintextra("appln_no", "countrycode");
