Part 2 Submission

Setup

The file name must be part2.zip. Files named differently will not be marked.

Unreadable files will not be marked (e.g., different file formats like. tar or .tar.gz). Code that does not build and execute will not be marked.

Make sure your project executes correctly, i.e., the application is built and installed in your emulator/physical devise. You can execute gradle assemble from the command line, which should execute successfully and generate the apk file app/build/outputs/apk/debug/app- debug.apk.

Clean up your project and remove unnecessary files by executing Build > Clean Project on Android Studio or /gradlew clean from the command line.

Export your Android Studio project as a zip file: File > Manage IDE Settings >Export to Zip File. The file name must be part2.zip.

Move/copy the exported file to the sem2hw folder you have created.

Finally, rerun/test your project again - unzip it and import it on Android Studio to check that everything works.

To start working on your solution, download part2.zip, unzip it locally, and import it as an Android Studio project.

Your first task is to implement a shopping list.

The data that you need to store for each shopping list is as follows:

• ListId: the unique id for a shopping list; this is an internal field and must not be shown anywhere in the app.

.

name: the name of the shopping list (a string); each list name must be unique.

image: an optional image to be associated with the shopping list.

For each product added to the shopping list, the app must allow the following fields:

.

.

name: the name of the product added to the shopping list (a string); cach product name must be unique in a shopping list.

quantity: a value indicating the quantity of the product. The text field for this must be of input type number.

unit: the unit for the item, which should be one of "Unit", "Kg", "Litre" (add more units if you wish), implemented in the UI using a Spinner view.

You will have to create the necessary Java classes to implement this. All your Java classes should be created in package uk.ac. Le.co2103.part2.
