"Xamarin.Android exposes three Android API level project settings:
- Target Framework – Specifies which framework to use in building your application. This API level is used at compile time by Xamarin.
- Android.Minimum Android Version – Specifies the oldest Android version that you want your app to support. This API level is used at run time by Android.
- Target Android Version – Specifies the version of Android that your app is intended to run on. This API level is used at run time by Android."
"[...] if the minimum Android version setting is lower than the target framework setting, your app can also run on earlier versions of Android. For example, if you set the target framework to Android 5.0 Lollipop and set the minimum Android version to Android 4.0.3 (Ice Cream Sandwich), your app can be installed on any platform from API level 15 to API level 21, inclusive."
