Commit unoplatform/uno#22676 broke Android+Skia+NativeAOT startup; see also unoplatform/uno#22832. This is noticeable when building and launching Uno.Gallery for Android+Skia+NativeAOT:

git clone https://github.com/unoplatform/Uno.Gallery.git
cd Uno.Gallery
git checkout b1943997ac1982722c240e3350ba3e0d92c5f55e
# anything between 6.6.0-dev.92 and "the fix" will fail
sed -i '' 's/"Uno.Sdk": ".*"/"Uno.Sdk": "6.6.0-dev.127"/g' global.json
dotnet publish -m:1 -r android-x64 -f net10.0-android -p:TargetFrameworkOverride=net10.0-android \
  -bl Uno.Gallery/Uno.Gallery.csproj -p:UseSkiaRendering=true -p:SkiaPublishAot=true \
  "-p:ApplicationTitleVendorSuffix= (NAOT)" -p:ApplicationIdVendorSuffix=.naot
adb logcat > log.txt &
adb install Uno.Gallery/bin/Release/net10.0-android/android-x64/publish/com.nventive.uno.ui.demo.naot-Signed.apk
adb shell am start com.nventive.uno.ui.demo.naot/crc64a57a145253f0f267.MainActivity

After launching the app, it crashes with:

PR unoplatform/uno#22834 fixes the issue, but before we merge it we want an integration test that exercises this codepath.

Uno.Gallery was chosen as the integration test app. :-)

(It can't be in unoplatform/uno because to reproduce the bug it needs to build against published NuGet paackages, and unoplatform/uno only uses in-tree build artifacts; see also.)

Update Uno.Gallery so that CI includes a new set of jobs, which:

1. Builds Uno.Gallery for Android+Skia+NativeAOT,
2. Installs the resulting APK on an emulator,
3. Launches the app via a new Instrumentation subclass.

We can't use "normal" UI Testing a'la f31954e because Uno.UITest doesn't support Skia, and the crash descibed above requires a Skia environment to observe.

As the crash is observed during app startup, we can instead use an Instrumentation which otherwise does nothing, then run:

adb shell am instrument -w com.nventive.uno.ui.demo.naot/my.MainInstrumentation

and check the output (logged to the executing console). If it has:

INSTRUMENTATION_CODE: -1

then the app launched successfully; otherwise, Something Went Wrong™ (presumably it crashed).

Pull request overview

Adds a CI integration test for Uno.Gallery that validates Android Skia + NativeAOT startup by building a NativeAOT APK, installing it on an emulator, and executing a minimal Android Instrumentation entrypoint to detect startup crashes.

Changes:

• Add an Android Instrumentation class used to validate app startup (no UI testing needed).
• Introduce a new CI stage/jobs to build the Skia+NativeAOT APK and run the instrumentation on an emulator.
• Refactor emulator provisioning logic into a shared script and reuse it from the existing Android UI test runner script.

LGTM. The shared android-sdk-emu.inc.sh extraction is a clean DRY improvement.

A few minor, non-blocking observations:

1. android-sdk-emu.inc.sh — mac-only default for CMDLINETOOLS: The default value is commandlinetools-mac-8512546_latest.zip. Since the emulator job runs on macos-14 this works today, but if a future caller runs on Linux, they'd need to override CMDLINETOOLS. A comment noting this assumption would help future maintainers.

2. android-sdk-emu.inc.sh — unconditional SDK level installs: The script installs platform levels 28, 34, 35, and 36 regardless of which API level the test actually targets (currently API 34 only). This is inherited from the original android-uitest-run.sh, so not a regression, but could maybe be trimmed in a follow-up to save CI time.

3. android-sdk-emu.inc.sh — commented-out shebang: Line 1 is # #!/usr/bin/env bash (commented). Since this file is sourced rather than executed directly, the shebang is correctly absent — but the commented-out line is a bit unusual. Consider removing it or adding a brief note that this file is meant to be sourced.

@agneszitte : thank you for the comments. They are all addressed in 4244648.

1. CMDLINETOOLS uses uname to choose between macOS (Darwin) and Linux package names, and errors out if it isn't set.
2. install_android_sdk for 34 and 35 have been removed. Now it only installs $ANDROID_SIMULATOR_APILEVEL and 36.
3. The commented-out shebang has been removed.
