I need a Java Application that can work on a mobile device

I am looking for a Java developer with experience working on Mobile Apps.

This application would be packaged as an APK.
Key features of app:

- It must scan/ allow manual input of foot items and their expiry date.
- It must store these items on a built-in database and display the foods.
- It should give users notification that food is about to expire or not
The notification should be configurable and in days, eg, in 3 days your milk will expire
- The application should also have an algorithm that tells users if they are wasting or not,
for example, if they have wasted food twice in a week, it will display what they have better and have a red mark,
if they have not wasted any food, it would display a green tick, and a message like 'Well done you haven't wasted anything'

- The application currently will be used by one user, myself so login details are not required.

Any further functions or requirements please contact me
