Back online again.
Here is a code sample:

public class controller extends Activity {

	/** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);

         Context currentContext = this;
         final BlinkAPI blinkAPI = new BlinkAPI(currentContext);


         lvVideo = (ListView)findViewById(R.id.ListViewVideo);
         radioTitleAdapter = new 
ArrayAdapter<String>(this,android.R.layout.simple_expandable_list_item_1,BlinkAPI.videoArrayList);
         lvVideo.setAdapter(radioTitleAdapter);
         }
         ...
        }

//*******************************************
        public class BlinkAPI {
	
	private static Context mContext;
	static ListView albumsLV, videoLV, tracksLV, artistsLV, radioLV;
	
	
	public BlinkAPI( Context ctx)
	{
		BlinkAPI.mContext = ctx;
		
		radioLV = (ListView )((Activity) 
mContext).findViewById(R.id.ListViewRadio);
		
	}
	
	private static void updateRadioTitles( )    {

             ...
             radioTitleAdapter.add(titleStr);		//PROBLEM
             radioTitleAdapter.notifyDataSetChanged(); //PROBLEM
     }

How do I get at radioTitleAdapter?
