Thank you for your report.

But It is not enough information to survey.
Could you give me more information such as
AiForms.Effects version, Xamarin.Forms version, Android SDK version, your linker settings and simple code in order to reproduce?

Thank you.

[chennakrishnakasukurthi]

Thank you for reply and Help muak.

AiForms.Effects - using the latest stable version
Xamarin.Forms version - 2.5.1.444934

Android SDK version - using latest Oreo (8.1), even i checked by changing in lower versions as well up to API level 21.

Am attaching a command to StackLayout and its working great in debug mode , while coming to release facing the issue when "Linking is set to be SDK Assemblies only."

Below is sample code.

Thanks,
Chennakrishna

Thank you for your additional information.

Though I tried building in the same environment, couldn't reproduce it.
My build worked it without problems.

I'm sorry I couldn't be of any help.

Hi all, I just ran into this issue, and deleting the /bin & /obj folder for the Android project worked for me.
