问题
I'm developing a Xamarin.Forms App (early stages) and have just set up AppCenter to build and distribute it. AppCenter takes the Xamarin.Android project, builds it successfully, signs with the same debug keys and makes the .apk available for download. I've tested in two different devices and the app installs successfully but won't run (opens and closes straightaway), no errors are shown.
If I deploy the app from Visual Studio it works fine.
- Xamarin.Forms 3.4.0.1008975
- Mono.Android v4.0.30319 (Xamarin.Android)
- Minimum Android 4.4 / Target 8.1
- Tested on Android 6 and 9 (both work if deployed from Visual Studio, and don't work with the distributed release from AppCenter)

Any suggestion is strongly appreciated.
回答1:
The solution to this problem was to disable the "Use Shared Runtime" property from the project options.
Instructions:
- Right click on the android project
- Go to Android Options
- Uncheck "Use Shared Runtime"
- Commit && push the changes
- Trigger a new build on AppCenter
