- Xamarin.Forms app (focus on Android)
- MVVM pattern
- API 30 target (tested on my Galaxy s9 which is API 29...)
- Permissions asked at startup
- It's worth noting that Google specifically discourages this practice, but for the purposes of proving that I can indeed implement such things, it makes far more sense to do permissions the "old" way.
- First up (at
App.OnStart()) we check the 3 permissions we need and if they are not granted we store each into an IEnumerable of a class that contains the permission name, description and rationale for display. - We then ask the user for each permission, and if we get it we remove that permission from our IEnumerable.
- When the first page is navigated to via our
AppShell, It will display those permissions we don't yet have, and present an option to ask again. - Originally I was going to use Xamarin.Essentials.Permissions, but it mapped confusingly with the (relatively new) ActivityRecognition permission in Android.
