Hi Kleverton, 
The mentioned issue occurs because of Xamarin.Forms dependency update in our SfListView control, we have upgraded Xamarin.Forms dependency version of SfListView to in our version (2019 Volume 2 – SP1 release). For using this Syncfusion update or later versions, you must have to upgrade Xamarin.Forms dependency in your project to Xamarin.Forms or higher and also needs to set the Android project target version as 9.0 to resolve this issue.  
We have mentioned the same as breaking changes in our release notes,   
Please find the documentation regarding target framework version,

I am using the latest version of the following:

Xamarin.Forms v4.2.0.848062 

and the Android project is already targeting the API 28.

However, I am not being able to build the project.

Any solution?
