    <p>So I have a <code>ExpandableListView</code> and inside the child views I have a <code>ListView</code>. When I click on one of the items it opens another activity. The problem occurs when I press back and click on another list item. When I do that I get the mentioned exception. I never use a bitmap, so I really don't know what is causing the problem, is the redrawing of the items the problem or?</p> <p>I read (ref. <a href="http://developer.android.com/training/displaying-bitmaps/cache-bitmap.html" rel="nofollow">Caching Bitmaps</a> ) that I should implement a caching mechanism, but I don't know how to start and what should I cache if I don't use any bitmaps? What am I missing here?</p> <p>The Logcat:</p> <pre><code>09-10 05:48:03.345: E/AndroidRuntime(21011): FATAL EXCEPTION: main 09-10 05:48:03.345: E/AndroidRuntime(21011):

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
