Automatically include NativeAOT debug symbols in Android App Bundles for Google Play #13206

Android framework version

net11.0-android (Preview)

Affected platform version

Reported with .NET SDK 11.0.100-rc.2.26504.105 and Android workload 37.2.0-rc.2.84.

Description

Automatically include the generated NativeAOT debug symbols in Android App Bundles (.aab) so Google Play can use them for native crash reports without a custom MSBuild target.

This is a focused follow-up to the comment by @tipa in #8903. The reporter states that explicitly adding the generated symbols to the bundle removed the Play Console warning about missing native debug symbols.

The SDK should package the generated symbols under BUNDLE-METADATA/com.android.tools.build.debugsymbols/<ABI>/, with the name lib$(TargetName).so.dbg, for each ABI included in a Release NativeAOT bundle. The symbols must match the native library in the bundle. Users should not need to specify ABI paths or add a custom target.

Acceptance criteria:

• Release NativeAOT bundles include the generated app symbols for each packaged ABI.
• Packaged symbols have build IDs that match the corresponding native libraries.
• Add automated coverage for the bundle paths and symbol inclusion.
• Confirm that Play Console accepts the symbols without the missing-symbol warning for the NativeAOT app library.

The reporter checked clean builds, matching build IDs, and local ndk-stack source-line lookup. Production crash symbolication in Google Play and Mono were not tested. This issue covers the generated NativeAOT app library symbols; the broader native crash support request remains in #8903.

Steps to Reproduce

1. Build a .NET 11 Android NativeAOT app in Release mode with PublishAot=true and AndroidPackageFormat=aab.
2. Upload the bundle to Google Play Console.
3. Observe the warning about missing native debug symbols.
4. Add the target below, rebuild, and upload the bundle. The reporter states that this removed the warning.

Did you find any workaround?

@tipa supplied this target for arm64-v8a and x86_64:

<Target Name="IncludePlayNativeSymbols" BeforeTargets="_BuildApkEmbed" Condition="'$(Configuration)' == 'Release' And '$(PublishAot)' == 'true' And '$(AndroidPackageFormat)' == 'aab'">
  <ItemGroup>
    <AndroidAppBundleMetaDataFile Include="com.android.tools.build.debugsymbols/arm64-v8a/lib$(TargetName).so.dbg:$(OutputPath)android-arm64/native/lib$(TargetName).dbg.so" />
    <AndroidAppBundleMetaDataFile Include="com.android.tools.build.debugsymbols/x86_64/lib$(TargetName).so.dbg:$(OutputPath)android-x64/native/lib$(TargetName).dbg.so" />
  </ItemGroup>
</Target>

Relevant log output

No build logs were supplied in the source comment. The Play Console warning quoted in #8903 is:

This App Bundle contains native code, and you've not uploaded debug symbols. We recommend you upload a symbol file to make your crashes and ANRs easier to analyze and debug.
