如何在可通过 App Wrapping 配置的 Xamarin Android App 中创建设置

Question

I have created a Xamarin Android App that has a single setting that the user is prompted to enter on first start-up. The setting is then saved using Xamarin.Essentials.Preferences.Set and retrieved from then on using Xamarin.Essentials.Preferences.Get .

I need to make this setting configurable via "App Wrapping". I have search high and low to work out how to do this, and I am not able to find an example.

I did want to create the setting in a way where it showed in the Android Settings app (Android Settings/Apps/App Setting for the app), thinking if the setting was accessible in there it would be configurable by App Wrapping, but was not able to find a way of doing this either.

My app doesn't have a settings UI and doesn't need one, I just need a way to make this one setting configurable via App Wrapping.

Can anyone tell me how to do this?

I am using the following environment:

• IDE: VS2019
• Device: Samsung Galaxy Tab Active Pro
• Android: 9
• Packages:
  • Xamarin.Android.Support.Core.Utils
  • Xamarin.Android.Support.Design
  • Xamarin.Android.Support.Supportv4
  • Xamarin.Essentials

Thank you for your time.

So I have found no evidence that in Android you can add a custom setting to the Android Settings app (Android Settings/Apps/App Setting for the app). Instead I have opted to save a file with my setting value to Xamarin.Essentials.AppDataDirectory , and this way App Wrapping can be used to pre-configure config value they want in the file. If the file is not there when the app starts then I prompt the user for the value on first start-up and write it there. So it can either be pre-configured via App Wrapping or the user can enter it.
