How use fastlane to deploy xamarin.forms to both iOS and Android?

Question

Now I'm ready to deploy to beta testers an app with Xamarin.Forms. I wonder if fastlane is the right tool.

I have found small pieces in how do this:

Only for iOS:

https://developer.xamarin.com/guides/ios/deployment,_testing,_and_metrics/provisioning/fastlane/

but not show how build the project first or how select the IPA/apk.

For appcenter:

https://github.com/Microsoft/fastlane-plugin-appcenter

But expect to have the IPA/apk already.

Answer 1

Use msbuild to build both your Android and iOS app. Afterwards you can upload the IPA with fastlane deliver to iTunes Connect and the APK with fastlane supply to Google Play Console.
