Post only relevant code next time. The error text plainly states that jObj is null.

I have no intention of trying to plough through that unformatted code dump. However, it is highly likely that the following line did not return an object:

JSONObject jObj = jsonParser.makeHttpRequest(AppConfig.URL_Order, "POST", params);

don't forget: use "pre" tags to format it

M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.
