android app with location synch to database

Application requirements I would like to have an ANDROID app that does the following: • user logs in to the app. when logged in user enters a new unique code to check in on location [ie:it should include current location street number etc + date and time. This info is then sent to some form of a database like a log. This log can be accessed by other people with authorisation • when leaving current location , user should clock out with the same unique ID number previously entered. Data is transmitted to database with current location street number etc + date and time. Total number of hours & minutes at location will be calculated on the database. ID should then expire and cannot be reused. • When user logs in next, a new code is required to log the current location street number etc + date and time to a database. Other features preferred but not mandatory Be able to track distance traveled by user with the app at all times. App/database to generate a new unique login code which can be sent to an admin via email or sms. End product: Finished work required no later than 3 days All source code should include consistent indentation and commenting. NB: please email me for further discussion or to arrange a phone call
