安卓应用程序开发代写｜Building a Tax Calculation App

Read the requirements thoroughly, answer the questions, and submit your answers in a compressed folder as instructed below.

Requirements:

Design and code a tax calculation app for Ontario based on the tax calculation rules found in “Combined Federal & Ontario Tax Brackets and Tax Rates Including Surtaxes” section of https://www.taxtips.ca/taxrates/on.htm.

The app will also account for RRSP contributions (i.e deduct RRSP from income when calculating tax, and display RRSP contribution limit for next year). RRSP limits are found on https://www.canada.ca/en/revenue-agency/services/tax/registered-plans-administrators/pspa/mp-rrsp-dpsp-tfsa-limits-ympe.html.

Your app should include a tax calculation class that takes care of everything related to taxation and one activity that shows a proper UI to the user and call the tax calculation methods properly. UI choices are up to your creative imagination. The app should allow its users to do some what-if analysis by providing a Slider to choose a multiplier (range:$0 to $27,230) for the RRSP deduction limit and calculate the tax as the user moves the slider. Here is a tutorial about Sliders: https://medium.com/analytics-vidhya/sliders-material-component-for-android-5be61bbe6726.

App data should be stored in Shared Preferences and retrieved whenever the app starts. A refresh button will be added to reload the data stored in shared preferences.
