votes

I use VS 2019 and Xamarin

I try to run the example (new project), but I need level API 19 (Android 4.4.2)

I was set target, minimun sdk. But get error while build

"Severity Code Description Project File Line Suppression State Error The $(TargetFrameworkVersion) for App4.Android (v4.4) is less than the minimum required $(TargetFrameworkVersion) for Xamarin.Forms (8.1). You need to increase the $(TargetFrameworkVersion) for App4.Android. App4.Android"

I have already tried select different Android version (5,6,7), but apart from 8 only.

I don’t. Search on sites they write, simple changed and use. But in reality, this is not so. In general, is it really possible to write below Android 8?

You need to "compile" using the latest version to use Forms. You can limit the runtime Minimum and Target versions, assuming you are are NOT deploying to the App Store. If you are calling Android level APIs you will need to manually check that you are only using the APIs available for level 19. - SushiHangover

As described here Expanding target API level requirements in 2019, In order to provide users with the best Android experience possible, the Google Play Console will continue to require that apps target a recent API level:

  • August 2019: New apps are required to target API level 28 (Android 9) or higher.
  • November 2019: Updates to existing apps are required to target API level 28 or higher.

and in future as well the target API level requirement will advance annually.

So you need to set target api version as required, however your app will work on all the phones with minimum sdk support. Minimum sdk version you can set based on the features supported by your app.

you could set your TargetFram Version to the latest version，then set the Minimum version to 19, Target Version to the same as TargetFram Version.

  • 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.

In general, the Target Android Version should be bounded by the Minimum Android Version and the Target Framework. That is:

Minimum Android Version <= Target Android Version <= Target Framework
