Updating the contents of a MergeAdapter

I have a pretty nifty MergeAdapter that contains a bunch of custom views and some custom ListAdapters. This MergeAdapter drives a ListActivity that displays content that get's updated every x seconds.

Currently I just create a new MergeAdapter, create and add all of my custom views (and this includes a few ImageViews) - and call setAdapter on the ListView in my activity.

After about 10 minutes of updates I run out of heap space and crash.

Ultimately because a new ImageView is added, and the following exception is thrown:

Caused by: java.lang.OutOfMemoryError: bitmap size exceeds VM budget

With simpler adapters (like ArrayAdapter), I would just update the data set, and call

on the adapter.

Is there a similar/recommended approach for "updating" a MergeAdapter? Or should I be walking the contents of a potentially complex MergeAdapter and updating individual Views?

notifyDataSetChanged() works, AFAIK. The current MergeAdapter has the code to ripple any changes from ListAdapters inside it to whatever has registered interests in changes in the MergeAdapter. This probably has not been tested enough, so if you have a sample app that demonstrates otherwise, post a link to it or send it to me (mention this SO question).
