ICT311 My Checkins

Case Study: MyCheckins

A startup company plans to develop an app which allows users to check in their daily activities. For example, a user can log the following information in the app:

• At 15:00 on 1 st August 2019, I visited Delicious restaurant with friends. We were there for half an hour. A photo is attached.

The requirements for the app are listed as follows:

1. When a user opens the app, the main user interface (List UI) appears, which includes the following items:

• A list of check-in records is shown. For each record, its "title", date, and place are displayed.
• A toolbar with two entries: "New", Help.

2. When the user clicks the menu item "New" in List UI, a new UI (Item UI) appears to allow the user to log a new record. The following items should be displayed: Title, Place, Details, Date, Location, Image, Share.

• "Title", Place, and Details are editable text fields.
• "Date" is a button, showing the current date. When clicked, it uses a dialog for users to pick up a date.
• "Location" has two parts: a (read-only) text view, and a button. The text view shows the GPS location (Latitude, Longitude) captured when this UI first shows. When the button Show map is clicked, it opens a new window to display the saved GPS location in Google Map.
• "Image" has two parts: an image view, and a button. When the button is clicked, it allows the user to take a picture of the receipt with the camera, and display it.
• "Share" is a button, allowing to send a summary of the record.
• When a user leaves this UI, the record details are saved. The List UI should be refreshed.

3. When the user clicks a record in List UI, its details will be displayed in a new UI (Item UI) similar to Requirement 2, but

• GPS location should not be updated. Display the same GPS location when this record was created.
• A button "Delete" to delete this record. Deletion should bring the app to the refreshed List UI.

4. When the user clicks the menu item "Help" in the List UI, a new UI appears to show help messages. The requirement is:

• Use Webview for the implementation.
• Use "https://www.wikihow.com/Check-In-on-Facebook" as the dummy content to show.

General implementation requirements:

• Requirement 2 & 3 should be implemented with one Activity.
• Use fragments for List UI and Item UI.
• Save receipt records with SQLite.
