Xamarin Forms NoSuchMethodError：没有静态方法 FormsViewGroup.sendViewBatchUpdate

Question

Updated Visual Studio Community and several NuGet packages in a working solution. Now when trying to run on an Android device or simulator getting the following error:

Java.Lang.NoSuchMethodError: no static method "Lcom/xamarin/forms/platform/android/FormsViewGroup;.sendViewBatchUpdate(Landroid/view/View;FFIZFFFFFFFF)V"

Downgrading is not an option.

Tried Clean All and delete bin and obj as suggested here but it didn't help. Tried different versions of Xamarin.Forms , also didn't help.

System:

macOS 10.15.3

Visual Studio Community 8.5

Xamarin.Forms 4.5.0.396

Min API 21

Target API 29

Answer 1

Turns out that R8 is removing this method for some reason. Adding the following Proguard rule fixed the issue:

-keep class com.xamarin.forms.platform.android.** {*;}
