Add a general Exception block to your JSON parsing try/catch and post the error that is caught:

//parse json data
 try{
     JSONArray jarray = new JSONArray(result);
        for(int i=0 ; i<jarray.length() ; i++) {
        JSONObject ob = jarray.getJSONObject(i);
        String titulo = ob.getString("title");
        String cate = ob.getString("catid");
        int cat = Integer.parseInt(cate);
        String coord = ob.getString("extra_fields_search");

        String latitud = coord.substring(0, 9);
        Float lat_f = Float.parseFloat(latitud);
        int lat = lat_f *1000000;

        String longitud = coord.substring(10, 19);
        Float lon_f = Float.parseFloat(longitud);
        int lon = lon_f*1000000;

        GeoPoint point = new GeoPoint(lat, lon);
        negocioNuevo = new Negocio(titulo, cat, point);
        listaNegocios.add(negocioNuevo);
        }  
 }catch(JSONException e){
     Log.e("miError de JSON", "Error parsing JSON "+e.toString());
 }catch(Exception e){
     Log.e("miError de General", "Error parsing data "+e.toString());
 }
