I am new to Android programming, but not to programming in general or Java. My question here is mainly about best practices.

I created a class MenuListActivity that extends a ListActivity that shows menu items in a list and starts another Activity when clicked. Each menu is a child class of the MenuListActivity class and implements a getMenuItems() method to create the menu items.

In my onCreate() method, I call that getMenuItems() to create a MenuListAdapter class that is then set as the adapter of the ListActivity's ListView.

However, sometimes I get an illegalStateException telling me that
"The content of the adapter has changed but ListView did not receive a notification."
. Notice it happens sometimes, not all the times. I do not touch the adapter in any other thread, in fact the adapter is set like this:
protected void onCreate(Bundle savedInstanceState) {
    ArrayList<menuadapteritem> menuItems = getMenuItems();
    this.setListAdapter(new MenuAdapter(this, menuItems));
Another possibility I can think of, is to create an Adapter member variable and call notifyDataSetChanged() on each update.

What would be the way to do this correctly? (And hopefully fix my crashes Wink | ;-) ).
