Tabview was working fine in the earlier versions of visual studio but it is causing problem only in the latest version of visual studio in my case Visual studio 16.4.296.

I have used tabview in xamarin forms and exception is occurring at LoadApllication(new App()); in MainActivity.cs Android project .

Exception:

Java.Lang.ClassNotFoundException:

Same issue here, my project 3 years old and it happened after upgrade to the latest..

I had to downgrade Xamarin.Forms from( 4.4.0.991265 to 4.3.0.991250) and downgrade Syncfusion controls from (17.4.0.39 to 17.3.0.14 The only one working for me).

I have the same issue!

I downloaded the sample and tried that, but STILL had the same issue. I upgraded VS2019 from 16.4.1 to 16.4.3 but still had the issue.

I was trying the app on a physical device running Android 5.0.2

I tried the sample on an emulator Android 6.0 API 23 and it worked!

I tried the sample on another physical device running Android 8.0.0 it worked.

I tried again on the physical device running Android 5.0.2 and it didn't work.

What is the minimum version of Android this should work on?

In the short term, I agree, but going forward, this issue needs to be addressed.
