这是一篇来自加拿大的关于构建一个税务计算应用程序的安卓应用程序开发代写
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.
