I recently decided to convert my simple ListView into a Separted List
View in order to categorize by list items. After creating my custom
ArrayAdapter to hold each section within my List
I noticed that adding sections and items to my ListView containing
default data when my application loads works fine. However, when I
call my update function to remove default data and append data from
background server communications my application crashes with a
ArrayIndexOutOfBoundsException.
I've searched the net and found a few others with similar issues but
found no solutions. I'm thinking it has to do with my getView of the
Custom ArrayAdapter I created (PlayerArrayAdapter).
After logging, I noticed that the first section returns views
correctly, however after the first list item of the second category
(section) is created, I get the exception. My initial thoughts were
that I was attempting to access data that did not exists, however that
was not the case as you can see below in my log:
