What's new

Issues fixed

Application and library build and deployment

  • Developer Community 790804, Developer Community 854497: Starting in Xamarin.Android 10.1, Mono.AndroidTools.RequiresUninstallException: The installed package is incompatible. Please manually uninstall and try again. interrupted deployment if the keystore used to sign the app had changed compared to the previous deployment. The fix for this issue is also included in Xamarin.Android 10.1.4.0.
  • Developer Community 854863: More than one device connected, please provide --device-id could prevent deploying successfully in projects configured to use the Android App Bundle publishing format when more than one device or emulator was attached.
  • Developer Community 869165: error CS0234: The type or namespace name 'CodeDom' does not exist in the namespace prevented building successfully in projects that used the word System as a dotted part of the default namespace for the project.
  • GitHub 4068: error MSB4044: The "CopyGeneratedJavaResourceClasses" task was not given a value for the required parameter "SourceTopDirectory". prevented incremental builds from completing successfully for projects using the Xamarin.AndroidX.Migration NuGet package.
  • GitHub PR 4106: Any unhandled exceptions in the Xamarin.Android MSBuild tasks would result in two MSBuild errors instead of one.
  • GitHub PR 4121: warning XA2000: Warning: Use of AppDomain::CreateDomain detected in assembly ... The AppDomain's will not be part of .NET 5 and therefore will be missing in newer Xamarin.Android releases. did not indicate that .NET 5 will still include the AppDomain type but only support use of a single AppDomain.
  • GitHub PR 4131: error ADB1000 was shown in addition to error ADB0030 if the ADB0030 error condition occurred.
  • GitHub PR 4205: Some of the Xamarin.Android MSBuild tasks were using foreground logging methods from background threads. That usage pattern could in theory lead to lock ups in the Visual Studio user interface.
  • Java.Interop GitHub 556: An app that referenced a library using the new support for Kotlin libraries could build successfully using an older version of Xamarin.Android but then fail when running on device. Xamarin.Android 10.2.0.99 adjusts one of the new APIs in Java.Interop.dll so that older versions of Xamarin.Android produce a linker error at build time.

Design-time build process
