问题 I am developing an android app with Xamarin. I tested in successfully through emulator and in test cloud manually but when I am trying to run it through VSTS, I am getting: Mono Shared Runtime is not supported.

问题 We have a "legacy" Xamarin.Android and Xamarin.iOS project. We would like to inject a Xamarin Forms component as a subview into a "native" Android and iOS view. The component is only available as a Xamarin Forms component and it is too expensive rewrite the entire app to Xamarin.Forms. The main question is how can we add complex Xamarin.Forms layouts as a subview in a "native" Xamarin.Android or Xamarin.iOS view? We have done some proof of concept work, and have successfully injected a XF

问题 what would be typical app size made with mono droid? I'm talking about "hello world" type of app. 回答1: With full linking enabled, currently the Hello World sample app is around 4MB in size. I say currently because I know the team is always working on improving the linker to bring app size down even more, so it's likely to go down even further in the future. You can read about the linker here. 来源： https://stackoverflow.com/questions/8294346/mono-for-droid-app-size

问题 Not being patient enough for the Mono for Android book I started going through the Android programming constructs and translate them to the Mono infrastructure. Seems like most the time the good folks at Xamarin and I think along similar lines so progress has been relatively pain free but on the AIDL issue I'm stuck. Was AIDL implemented?

问题 I'm done with my app and now I'm trying to build the .apk and test it on my phone (without debug, in release mode). Setting the Linking to " None " everything works fine. The Problem here is, that the App is too large - its 20MB and thats rubbish. I read that article about Linking: Click Here So I tried " Sdk Assemblies Only " and " Sdk and User Assemblies ". The second option (Both Assemblies) failed directly, I wasn't even able to see the first screen (Login) of my App. With Linking set to
