Actually i am working on livechat application i have four part for my application.after login screen there is open a window in which i am showing the list of visitor visiting the site.my data of the list is updating each after 3 seconds.this part is working fine.the list the list row i am showing the data like ipaddress,statustext,noofvisit,buttontext,durationtime extra.

When any new chat request come(list refresh if status text is chatrequest) and if i click on accept the chat accepted and call go to server status change and a new window will open chat window.this part is also working fine.the issue is for chat window for sending message a call go to server and for response message a call also go.

My issue is that the in chatting part 5 or 6 message are going and receiving after that i am getting null pointer exception.In chat window i am using code like following

TL;DR

630 lines of code is too much to ask of anyone to go through and try to make sense of. You're accessing element 0 of an ArrayList that doesn't contain any elements in line 189 of the Chat class - armed with that knowledge it should be trivial for you to find which ArrayList object that is, and take steps to prevent it from happening.
