I have an application with various tabs (on a tabhost), each tab is an activity that extends activity, and haves some textfields and things on it.On my first tab i am using it for showing the listview which is using customadapter and this list is getting data from server and data is updating after each 3 seconds in list.App is working fine but sometime it is being crashed and showing java.lang.NullPointerException in CustomAdapter in some point.

my code is mention below my class is like this
