@pictos I tried removing the [DynamicDependancy] after your suggested changes and it crashed. But adding those constructors won't hurt so I added them and and the attribute back. I am having no issues with running mediaElement with the test sample provided by developer now. Ty for the idea.

@pictos This as is now fixes the issue that was brought up. The OP has confirmed this fixes it.

Just to let you know, this is more a bandwidth than a proper fix. Those constructors are called from Java world when the managed object is collected, so at some point, the code tries to access a disposed MediaElement, would be good to get the stack trace and see the real issue

I agree 100 percent with that. I have already started investigating the issue. I see this as a workaround until a proper fix can be done. I just don't want to leave mediaElement in a non working state for some users.

Pull request overview

This PR aims to prevent .NET 10 trimming/linking from removing MediaElement public constructors by adding trimming annotations on the Android MauiMediaElement implementation (to address the Android crash/regression in #3114).

Changes:

• Added [DynamicDependency(DynamicallyAccessedMemberTypes.PublicConstructors, typeof(MediaElement))] annotations to Android MauiMediaElement members.
• Introduced additional Android MauiMediaElement constructor overloads and adjusted the JNI handle constructor to call the appropriate base constructor.
