My code is throwing an IndexOutOfBounds exception at some point (can't figure out where). The exception log below:

As you can see, this log doesn't show any class I wrote myself. To understand better what is happening, here is what my app do at this point: - A http request is made to fetch an array of data from server - I use this array to populate a ListView with several options user can choose
After a few tests, I've noticed that this error only occurs when the jsonArray I get from server has between 1 and 7 elements. If a specific search returns, let's say, 0, 7, 40 items, everything is ok. When I get only one element, or 4 elements, the app crashes.. No idea at all why this happens...
the method below is executed right after I get response from server:
private void didDownload(JSONObject result) {
try {
listingsArray = concatArray(listingsArray, result.getJSONArray("empresas"));
Location currentLocation = PreferenceData.getUserLocation(myContext);
for(int i = 0, j = listingsArray.length(); i < j; i++){
JSONObject c = listingsArray.getJSONObject(i);
JSONObject listing = c.getJSONObject("listing");
double listingLatitude = listing.getDouble("latitude");
double listingLongitude = listing.getDouble("longitude");
Location listingLocation = new Location("");
listingLocation.setLongitude(listingLongitude);
listingLocation.setLatitude(listingLatitude);
float distance = currentLocation.distanceTo(listingLocation);
listingsArray.getJSONObject(i).put("distancia", distance);
}
imageURLs = new String[listingsArray.length()];
for(int i = 0; i < listingsArray.length(); i++) {
String url = ImageUrlBuilder.buildURL(listingsArray.getJSONObject(i).getString("thumb"), myContext, "thumb");
imageURLs[i] = url;
}
} catch (JSONException e) {
Log.e(TAG, "Erro no Json");
}
tamanho = listingsArray.length();
cacheUpdated();
}
while debugging, step by step, the method below was the last one I could follow before the crash (this one runs in a worker thread, from another class, to load images into my listview items)
class PhotosLoader implements Runnable {
PhotoToLoad photoToLoad;
PhotosLoader(PhotoToLoad photoToLoad){
this.photoToLoad=photoToLoad;
}
@Override
public void run() {
try{
if(imageViewReused(photoToLoad))
return;
Bitmap bmp=getBitmap(photoToLoad.url);
memoryCache.put(photoToLoad.url, bmp);
if(imageViewReused(photoToLoad))
return;
BitmapDisplayer bd=new BitmapDisplayer(bmp, photoToLoad);
handler.post(bd); //here is where I can't debug further... The IndexOutOfBounds exception isn't caught below...
}catch(Exception e){
e.printStackTrace();
Crashlytics.logException(e);
}
}
}
I'm not sure if these methods have something to do with the error... Thanks in advance for any directions on this!
[UPDATE] getView():
/**
* Create a new ImageView when requested, filling it with a
* thumbnail or a blank image if no thumb is ready yet.
*/
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
// check if user reached end of list
if(shouldLoadMoreData(position)){
loadMoreData();
}
// can we recycle an old view?
if(convertView == null) {
convertView = mInflater.inflate(R.layout.listing_listview_item, parent, false);
holder = new ViewHolder();
holder.listingTitle = (TextView) convertView.findViewById(R.id.listingTitle);
holder.distancia = (TextView) convertView.findViewById(R.id.distancia);
holder.address = (TextView) convertView.findViewById(R.id.address);
holder.promotions = (TextView) convertView.findViewById(R.id.promotions);
holder.img = (ImageView) convertView.findViewById(R.id.img);
holder.loading = (ProgressBar) convertView.findViewById(R.id.loading);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
try {
JSONObject c = listingsArray.getJSONObject(position);
JSONObject listing = c.getJSONObject("listing");
double distance = c.getDouble("distancia");
String dist = (distance > 1000) ? String.format("%.1fkm", distance/1000) : String.format("%dm", (int)distance);
int p = c.getInt("promotions");
String promotions = (p > 1) ? p+" Ofertas" : p+" Oferta";
holder.listingTitle.setText(listing.getString("title"));
holder.address.setText(listing.getString("address"));
holder.promotions.setText(promotions);
holder.distancia.setText(dist);
} catch (JSONException e) {
e.printStackTrace();
}
// do we have a thumb stored in cache?
imageLoader.DisplayImage(imageURLs[position], holder.img, holder.loading);
return convertView;
}
