Using android package in shared project code

Matt Dietsche 1

I'm adding android-specific "Xamarin.Android.MP4Transcoder" NuGet package only to the android project in a shared project. My understanding is that I can use the package in shared project files by wrapping it in #if __ANDROID__ statements. But when I try adding the namespace in a shared project file, visual studio says that the namespace doesn't exist. Can I not do this?

I understand that it might not be the best way to do it, but I'm working on adding something to an existing project, and refactoring things to use interfaces for sharing code across platforms isn't feasible for me at the moment.

Hi @Matt Dietsche , maybe you need to download this nuget package into both of your iOS and Android real projects, please refer this answer: https://stackoverflow.com/a/54243683/14324452

Hey @Dylan Zhu-MSFT , thanks for your response. This is an Android specific package, so the package manager won't actually let me install it in either the iOS project or the shared project.

Hi @Matt Dietsche , thank you for reply. Please try to go to "C:\Users[use name].nuget\packages\xamarin.android.mp4transcoder\1.0.47\lib\MonoAndroid10", and add "Xamarin.MP4Transcoder.dll" as reference in your ios project. And then check if it could work.
