what should profile picture of user , show activity?

just add following parameter in existing code

parameters.putstring("fields", "id,name,email,gender,birthday,picture.type(large)");

picture.type(large) return url profile picture

by way can url jsonobject returned facebook this:

profilepicurl = object.getjsonobject("picture").getjsonobject("data").getstring("url");
