JSONArray apps = new JSONArray(result);
Log.i("LOG", "log = " + apps.length());
for (int i = 0; i < apps.length(); i++) {
JSONObject object = apps.getJSONObject(i);
StructApplication application = new StructApplication();
application.id = object.getString("app_id");
application.name = object.getString("app_name");
application.price = object.getInt("app_price");
application.logoUrl = object.getString("app_logoUrl");
