Thanks for contributing this! I wasn't aware of the need for the NDK when I put this PR up 🙏
I've made some comments which I think would bring the changes more in line with our script style such as it is.
I'm not sure if this code actually belongs within this script since it isn't dealing with the SDK itself but I think we can revisit that question later if nobody else has opinions.
scripts/install_swift_sdk.sh
Outdated

Is there no way we can know this ahead of time? We control the whole system here from a blank VM.

If we do need to exit here can we use fatal and explain what the issue is?

Do we actually need the cd here can we just refer to things using longer paths?

We change directories so that the NDK is downloaded adjacent to the artifactbundle, otherwise it is in the current folder, which seems like it might cause confusion and clutter.
The path search is unfortunately because the swiftpm configuration folder varies based on OS and configuration. I observed that for the swift-nio test run that it was /root/.swiftpm/swift-sdks, but I'm not sure if that will always be the case.
Note that we could do this and it would just work, plus it would allow us to avoid needing to change directories:
cd $(swift sdk configure --show-configuration swift-DEVELOPMENT-SNAPSHOT-2025-10-17-a-android-0.1 | grep 'sdkRootPath: ' | head -n 1 | cut -f 2- -d ':')/../../../..
That's pretty gnarly, but let me know if you think it is preferable and I will implement it.

@marcprux Could you enable write access to your branch from maintainers so that we can merge in |
I'd be happy to, but I don't see the usual "Allow Edits by Maintainers" checkbox. 😕 Anyway, I've merged in |

Great! Let me know if you hit any more snags with the Android workflow in future PR checks… |

Fixes the Android CI workflow
Motivation:
The recently-added Android SDK workflow fails (as mentioned at #3418 (comment)). The confusing error message is due to a post-install step that is needed to download and link the Android NDK into the Swift SDK's artifactbundle.
This PR also adds a one-line fix to Sources/NIOPerformanceTester/main.swift that gets it building for Android so the entire swift-nio package can be built.
Modifications:
Adds a post-install step to the SDK installation that is needed for the Swift SDK for Android. This is the same technique used by swiftlang/github-workflows#172, and is described as a necessary step in the Android getting started guide
Result:
The "Android Swift SDK" CI check should now pass successfully. See an example at https://github.com/swift-android-sdk/swift-nio/actions/runs/18761057590/job/53525442382
Note:
This PR will not pass the Android check until it has been merged, because it relies on being able to down the the script https://raw.githubusercontent.com/apple/swift-nio/main/scripts/install_swift_sdk.sh from
apple/swift-nio/main, which will not include the Android fix until the PR is merged. But once it is merged, the Android SDK CI should start passing.
