It appears that there is a bug in android where subactivities' views are not kept isolated from each other (like AppWidgetHostView does). Android generates the same set of id's across applications and I found that another subactivity in the activity group has the same id assigned to it and it's a list view. I am going to suppress saving instance state for now, as a temporary fix but I understand that won't enable me to get the default state saving functionality built into android. Should I open a bug?
