Android studio coder needed helping at cheaper rate

Hi, I have an android codes needed for my personal project but there's errors. I have brought the live domain as my localhost xampp panel doesnt work. For my project, I have an app for food ordering with the database and also an admin panel. for now, my database is working but it is not link to android app. Meaning when i run android project, build successfully but cannot login or register into app. Then when login, it should be able to see menu list for user to order. My promotions tab when click will close the whole app. The order wise i havent get to try it yet so im not sure if there is any problem with that, since i cant get in the app now. Hope to hear from you soon.
