Context: https://github.com/dotnet/android/issues/9133 Context: https://learn.microsoft.com/visualstudio/msbuild/copy-task?view=vs-2022 We sometimes get collisions between the Design-Time-Build (or AntiVirus) and our main build. This can result in errors such as: Error (active) XALNS7019 System.UnauthorizedAccessException: Access to the path 'D:\Projects\MauiApp2\obj\Debug\net9.0-android\android\assets\armeabi-v7a\MauiApp2.dll' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.File.InternalDelete(String path, Boolean checkHost) at Microsoft.Android.Build.Tasks.Files.CopyIfChanged(String source, String destination) in /Users/runner/work/1/s/xamarin-android/external/xamarin-android-tools/src/Microsoft.Android.Build.BaseTasks/Files.cs:line 125 at Xamarin.Android.Tasks.MonoAndroidHelper.CopyAssemblyAndSymbols(String source, String destination) in /Users/runner/work/1/s/xamarin-android/src/Xamarin.Android.Build.Tasks/Utilities/MonoAndroidHelper.cs:line 344 at Xamarin.Android.Tasks.LinkAssembliesNoShrink.CopyIfChanged(ITaskItem source, ITaskItem destination) in /Users/runner/work/1/s/xamarin-android/src/Xamarin.Android.Build.Tasks/Tasks/LinkAssembliesNoShrink.cs:line 161 at Xamarin.Android.Tasks.LinkAssembliesNoShrink.RunTask() in /Users/runner/work/1/s/xamarin-android/src/Xamarin.Android.Build.Tasks/Tasks/LinkAssembliesNoShrink.cs:line 76 at Microsoft.Android.Build.Tasks.AndroidTask.Execute() in /Users/runner/work/1/s/xamarin-android/external/xamarin-android-tools/src/Microsoft.Android.Build.BaseTasks/AndroidTask.cs:line 25 MauiApp2 (net9.0-android) C:\Program Files\dotnet\packs\Microsoft.Android.Sdk.Windows\34.99.0-preview.6.340\tools\Xamarin.Android.Common.targets 1407 If we look at the [MSBuild `<Copy/>` task][0] we see that it has a retry system in the cases of `UnauthorizedAccessException` or `IOException` when the code is `ACCESS_DENIED` or `ERROR_SHARING_VIOLATION`. The `<Copy/>` task also has public `Retries` and `RetryDelayMilliseconds` properties to control behavior. Duplicate that kind of logic into our `Files.Copy*IfChanged()` helper methods. This should give our builds a bit more resiliency to these kinds of issues. Instead of adding new `Files.Copy*IfChanged()` method overloads which accept "retries" and "retryDelay" parameters, we instead use environment variables to allow overriding these values: * `DOTNET_ANDROID_FILE_WRITE_RETRY_ATTEMPTS`: The number of times to try to retry a copy operation; corresponds to the `Copy.Retries` MSBuild task property. The default value is 10. * `DOTNET_ANDROID_FILE_WRITE_RETRY_DELAY_MS`: The amount of time, in milliseconds, to delay between attempted copies; corresponds to the `Copy.RetryDelayMilliseconds` MSBuild task property. The default value is 1000 ms. [0]: https://github.com/dotnet/msbuild/blob/main/src/Tasks/Copy.cs#L897 |

android-tools
android-tools is a repo to easily share code between the xamarin-android repo and the .NET for Android commercial tooling, such as IDE extensions, without requiring that the IDE extensions submodule the entire android repo, which is gigantic.
Build Requirements
-android-tools requires .NET 6 or later.
Build Configuration
The default make all target accepts the following optional
make(1) variables:
$(CONFIGURATION): The configuration to build. Possible values includeDebugandRelease. The default value isDebug.$(V): Controls build verbosity. When set to a non-zero value, The build is built with/v:diaglogging.
Build
To build android-tools:
dotnet build Xamarin.Android.Tools.sln
Alternatively run make:
make
Tests
To run the unit tests:
dotnet test tests/Xamarin.Android.Tools.AndroidSdk-Tests/Xamarin.Android.Tools.AndroidSdk-Tests.csproj -l "console;verbosity=detailed"
Build Output Directory Structure
There are two configurations, Debug and Release, controlled by the
$(Configuration) MSBuild property or the $(CONFIGURATION) make variable.
The bin\$(Configuration) directory, e.g. bin\Debug, contains
redistributable artifacts. The bin\Test$(Configuration) directory,
e.g. bin\TestDebug, contains unit tests and related files.
bin\$(Configuration): redistributable build artifacts.bin\Test$(Configuration): Unit tests and related files.
Distribution
Package versioning follows Semantic Versioning 2.0.0.
The major version in the nuget.version file should be updated when a breaking change is introduced.
The minor version should be updated when new functionality is added.
The patch version will be automatically determined by the number of commits since the last version change.
Xamarin.Android.Tools.AndroidSdk nupkg files are produced for every build which occurrs on Azure Devops.
To download one of these packages, navigate to the build you are interested in and click on the Artifacts button.
Alternatively, "unofficial" releases are currently hosted on the Xamarin.Android feed.
Add the feed to your project's NuGet.config to reference these packages:
<configuration>
<packageSources>
<add key="Xamarin.Android" value="https://pkgs.dev.azure.com/xamarin/public/_packaging/Xamarin.Android/nuget/v3/index.json" />
</packageSources>
</configuration>
