Android App - Barcode Scanner (ZXing), SQLite database, UI

PROJECT OVERVIEW ----------------------------- --- I am on a TIGHT deadline. This project needs to be done in 7 days --- - I need Android app that will allow users to query a local database and add items to a cart. - The program will integrate the ZXing barcode scanner to scan ISBN barcodes. - It will also allow the user to type in a number instead of scanning. - The database will all be local (in SQLite db file). - The database will have just TWO tables. One for bibliographic data and one for the current cart. FUNCTIONALITY -------------------------- - The program will have a "home" screen - Home screen has two buttons: "Scan ISBN" and "Type ISBN" - Home screen will display a total price of all items in the cart. - Home screen also has a "Reset" button, which empties all items from cart - If the user chooses to "Scan ISBN", program will use the ZXing library to scan ISBN barcode. - If the user chooses to "Type ISBN", program will show a numerical keyboard for typing ISBN - Query SQL database for product information (Title, Author, Price) and display - Allow user to "Accept" or "Decline" - Take user back to home screen. - Aesthetics are not important. OTHER NOTES ------------------------------ - I will own full copyright and ALL source files - App will be on Android Market as a free app - You will guarantee a 2 week free bugfix period - I will need your report on development progress every day;
