    indicator=(ImageView)convertView.findViewById(R.id.icon_img);
    if ( getChildrenCount( groupPosition ) == 0 ) {
        indicator.setVisibility( View.INVISIBLE );
    }
    else {
        indicator.setVisibility( View.VISIBLE );
        indicator.setImageResource( isExpanded ? 
       R.drawable.ic_arrow_up : R.drawable.ic_arrow_down );
    }

You can also define your own groupIndicator in XML:

First define your own drawable (I called it list_view_group_indicator.xml and placed it in the drawable directory)

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_expanded="true"
        android:drawable="@drawable/packagexgeneric" />
    <item
        android:drawable="@drawable/packagexgenericclose" />
</selector>

Then use it as a drawable for your expandableListview

<ExpandableListView android:id="@+id/server_show_list"
    android:layout_width="fill_parent"android:layout_height="wrap_content"
    android:groupIndicator="@drawable/list_view_group_indicator" />

ok 

   public View getGroupView(int groupPosition, boolean isExpanded, View convertView,
            ViewGroup parent) {

    if(getChildrenCount(groupPosition)==0)
    {
          // how do i hide the group indicator ?

    }

So, how can modify the group indicator for empty groups ?

You can try the setGroupIndicator(Drawable) method of ExpandableListView.
