The 0 is not the problem.
You have a group with no children, and that's quite logical, because
that's exactly the case you are trying to customize (hide the group
indicator).
The problem is the code executed in that case, under the "if":
"indicator.setVisibility(View.INVISIBLE)".
I believe that "indicator" is null.
Which is also quite logical, because ExpandableListView doesn't use a
view to draw the indicators (either group or child), it directly draws
Drawable objects on top of any children or group items.
Where does the "indicator" in your code come from? What is its value in
the code you posted, is it null?

indicator is an imageview.Then , I tried to set the visibility of
this image depending on the number of children. But when I debug the
"if( getChildrenCount( groupPosition )==0) {
indicator.setVisibility( View.INVISIBLE );. " the app crashes. The
"0" is the problem, beacause when I turn it to another number it works
perfectly.
Thanks for your answer.
