[Android] two ways to get photo in the List View

int tmp_index = 0;
  final List < Map < String, Object >> data = new ArrayList< Map< String, Object >>();
  for (int i = 0; i < camNameArr.length; i++) { 
    Map< String, Object> item = new HashMap< String, Object>();
    item.put("name", camNameArr[i]);

    //----get photo from project    
    Log.e("camIDArr[i] " +i,""+camIDArr[i]);
    Log.e("*tmp_index",""+tmp_index);
    item.put("image", mPics[i]);

//   // ----get photo from sd card
//   String photoName = "main" + (i + 1) + ".jpg";
//   // new DownloadImagesToSdCard("http://spaceflightnow.com/news/n0211/04soho/sun.jpg",photoName, savePhotoPath);
//   item.put("image", savePhotoPath + photoName);
   data.add(item);
