📜 Description

Keep Android's generated installation ID independent of the Data Collection userInfo option.

Restore installation IDs for the default distinctId, event and exit-info user.id, device context device.id, and hybrid scope serialization when userInfo=false. Application-configured user and distinct IDs remain authoritative. Automatic IP enrichment continues to follow userInfo.

Remove the now-unused isUserInfoWithLegacyAlways() resolver variant and update the Android policy tests.

💡 Motivation and Context

The installation ID is a random identifier generated once per app installation and historically remains available independently of sendDefaultPii. The Data Collection specification defines userInfo around automatic user information, but does not require it to control installation identity, device identity, or session correlation.

Keeping the installation ID independent preserves existing Android behavior and avoids changing crash-free user, session, log, metric, device-context, and hybrid SDK correlation when applications opt out of automatic user information.

💚 How did you test it?

• ./gradlew ':sentry-android-core:testDebugUnitTest' --tests='*AndroidOptionsInitializerTest*' --tests='*ApplicationExitInfoEventProcessorTest*' --tests='*DefaultAndroidEventProcessorTest*' --tests='*DeviceInfoUtilTest*' --tests='*InternalSentrySdkTest*'
• ./gradlew ':sentry:test' --tests='*DataCollectionResolverTest*'
• ./gradlew spotlessApply apiDump
• git diff --check

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• I updated the docs if needed.
• I updated the wizard if needed.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.
• Public API changes reviewed by another Mobile SDK team member or implemented according to the develop docs spec.

🔮 Next steps

Continue the remaining Data Collection configuration and release-gate work.
