¿Por qué ocurrió este error? java.lang.RuntimeException: ImageLoader debe ser init con la configuración antes de usar

Question

He descargado un código de ImageDownloader de gitHub (from Here) Ahora cuando intento descargar la imagen de mi servicio web obtengo esta Excepción de tiempo de ejecución "ImageLoader debe estar init con la configuración antes de usar ".

No puedo resolverlo.

Y esta mi adaptador:

public class CustomAdapter extends BaseAdapter 
{ 
    private Context context; 
    private ArrayList<String> logo_URL; 

    private ListContent listContent; 
    private ArrayList< TeamDataClass> teamdata = null; 
    private ArrayList<EventDataClass> eventdata = null; 
    private DisplayImageOptions options; 
    private ImageLoader imageLoader; 

    public CustomAdapter(Context context,ArrayList<String> logo_URL,ArrayList<TeamDataClass> teamdata, ArrayList<EventDataClass> eventdata) 
    { 
     this.context = context; 
     this.logo_URL = logo_URL; 
     this.teamdata = teamdata; 
     this.eventdata = eventdata; 
     options = new DisplayImageOptions.Builder() 
     .showImageForEmptyUri(R.drawable.image_for_empty_url) 
     .cacheOnDisc() 
     .imageScaleType(ImageScaleType.EXACT) 
     .build(); 
     imageLoader= ImageLoader.getInstance(); 
    } 

    //@Override 
    public int getCount() 
    { 
     return teamdata.size()/2; 
    } 

    //@Override

     if (convertview == null) 
     { 
      convertview = inflater.inflate(R.layout.custom_list_score, null); 
      listContent = new ListContent(); 
      listContent.team_logo2 = (ImageView) convertview.findViewById(R.id.team_logo2); 
      listContent.team_logo1 = (ImageView) convertview.findViewById(R.id.team_logo1);

      convertview.setTag(listContent); 
     } 
     else 
     { 
      listContent = (ListContent) convertview.getTag(); 
     } 
     listContent.status.setText(eventdata.get(arg0).status);

Answer 1

He añadido esta línea en mi Constructor y su trabajado para mí ...

imageLoader.init(ImageLoaderConfiguration.createDefault(context)); 

Answer 2

protected ImageLoader imageLoader; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.activity_main); 

imageLoader = ImageLoader.getInstance(); 
imageLoader.init(ImageLoaderConfiguration.createDefault(this));
