Looks like there is something wrong with data used to construct the
SimpleExpandableListAdapter. Perhaps groupData or childData.
The code that crashes is this (as of Cupcake):
return mChildData.get(groupPosition).size();
Perhaps the values in groupData and childData are out of sync, one
including the top-level group, and one missing it?

if you look at the stack trace - it's all google code.
i'm just clicking on the group button.
i believe my code does not figure in this stack dump.

Well, getChildrenCount method is the one which is throwing this exception.
You are requesting an index 0 of an array which doesn't have any elements.
Can you post some code?
