Mobile app need code cleaning and gui change

I have 2 Android apps. All the apps connect to an api and for the most part it works. The only issue I'm having is that last app developer left some static url paths/strings and it causes erroneous results. The only thing needed to be done is to make the apps follow the path strings. I also need a minor GUI change for which I will provide psd file. I would need the app to be uploaded to Android for us, this is very important. The apps will need to work with the latest KitKat be backward compatible with prior versions such as gingerbread. I need the work to be done in 2 or 3 days max. Also, I need the freelancer to be available within my time zone (GMT 7:00). It is ok at the time zone you're in, but I need chat with you when going over details. For this reason, I wont favor companies to bid, but only for freelancers that are independent, or that at least have the time after your normal day work to attend to the task. I'll provide more details when I'm interested in a bid. Additional Project Description:
