'ExpandableListAdapter' is abstract; cannot be instantiated

I was working on the tutorial at http://javapapers.com/android/android-expandable-listview/.

I was working on the MainActivity.java section, and I got this error:

'ExpandableListAdapter' is abstract; cannot be instantiated

How can I fix this?

I know it's a little old question but this answer might help to those facing similar issue. Essentially, you are getting that error as ExpandableListAdapter is an abstract class. To get rid of it implement your own Adapter. You might refer to following post to understand how it can be done - http://www.androidhive.info/2013/07/android-expandable-list-view-tutorial/. Hope this helps. Thanks.
