CSE 382
Project #2 - Mobile Application: US Tax Information
Fall 2022
You will create a mobile app, USTaxes, using Xamarin that executes queries regarding tax returns filed in the US. The mobile app will be based on the following screenshots:
- A dollar amount provided by the user
- The name of a city provided by the user
- The name of a state provided by the user
- The type of query to perform (provided by the user). There are two types of queries:
- The first, termed amount, finds all zip codes that have an average tax return equivalent to the dollar amount provided by the user (i.e., box #1) ±$100.
- The second, termed city state, finds all zip codes that are in the city-state provided by the user.
- A button to initiate the query.
- The scrollable list of zip codes that are produced by the query. The results are sorted by zip code, with city, state, and average tax return shown too.
Notes.
● For a given zip code, the data file can include multiple options. For example, 45056 is associated with six options:
… 45056 STANDARD OXFORD OH ...
… 45056 STANDARD MIAMI UNIV OH …
You are to discard all but the first instance of a given zip code.
● You can repurpose your USLocations class from a previous project (copy it into your new project and revise it); you may also find it necessary to add methods/fields to the class. If the asynchronous portion of the code causes runtime problems, please drop back to doing regular, synchronous, IO.
● You are expected to alter the appearance of the app in order to make it more appealing and usual than the one displayed above. This includes, but is not limited to:
○ Colors
○ Font sizes
○ Labels to identify purpose of controls
○ Positions/layout of controls
○ Type of controls used for user input for effective, and resilient, user input
○ Enabling/disabling controls
○ You can make any changes you wish, as long as the spirit of the requirements are still met.
● Your program should not crash, regardless of the input entered by the user.
● The zipcodes.tsv must be treated as an embedded resource. This is necessary so that the mobile app has the original data file when it is deployed to an actual mobile device.
● Your program should not crash.
● Average tax return is to be computed as total wages in that zipcode divided by the total number of tax returns filed. A zip code (e.g, 45056) can appear multiple times in the file under multiple names (e.g., Oxford, Miami University, etc). For computing purposes, use the first one that appears in the file.
● XAML is not required for this project.
Submission.
● The submission for this assignment differs from the prior assignment.
● Here are the submission instructions to use when ready to submit to Canvas.
● Some extra notes for the video
○ At a minimum do the following searches:
■ amount: $25000
■ amount: $40000
■ citystate: Cleveland, OH
■ citystate: Detroit, MI
○ Make sure that you illustrate that your program does not crash. Do this by entering illegal information into any place the user can enter information. Any error checking that you do should be exhibited in your video.
○ The maximum length of video should be 4 minutes.
Scoring.
● (75) Correctness. Your application must operate correctly.
● (10) Robustness. Your program should not crash under any circumstances.
● (15) Appearance. Your application will be subjectively evaluated for visual and operational appeal. Implementing a basic application, such as the one displayed above, will receive 0 points on this criteria.
○ 13-15: Professional appearance/operation.
○ 10-12: Nice appearance/operation. Significantly better than the default.
○ 3-9: Some attempt was made to improve on the default application but the appearance/operation has an obvious need for improvement.
○ 0-3: Approximately the same quality as the default application.
