Results Functioning well to do demo, not production-ready Wish to have more time to work on this project. ~ 5800 lines of Android client Java code ~60 hours

Future Works The features of this application needs to be polished and extended: Swipe View List used in My Sale and Watch List Activity can be polished that the icon of the item can be the thumbnail image of the book. On the Main Activity the user should be allowed to sign out and switch to different account. On Setting panel there should be option to change application permission access. The view of Message Activity can be enhanced. Search for textbook sales (“I want to buy” option) function can be more intuitive and user-friendly An introduction animation can be included. Integration with social media function.   The code base and the performance of the application can be optimized: Many unreferenced classes and library can be eliminated. Some custom libraries can classes can be simplified Better handling of tasks and services Better handling of threads and exceptions, which includes more clear separation of UI threads and non-UI threads to improve user experience. Better handling of debugging and testing The server REST API needs to be able to handle image URL link in the request or we may to develop Android API instead of REST.
