Perfect! Now here's the summary and final commit:

## Summary

I've successfully addressed all 7 review comments:

**SentryAndroidOptions.java:**
1. Changed `@ApiStatus.Internal` to `@ApiStatus.Experimental` for both `setEnableApplicationStartInfo()` and `isEnableApplicationStartInfo()` methods

**AndroidOptionsInitializer.java:**
2. Removed the version check (`if (buildInfoProvider.getSdkInfoVersion() >= 35)`) since ApplicationStartInfoIntegration handles version checking internally
3. Updated to pass `BuildInfoProvider` to the integration constructor
4. Added test in `AndroidOptionsInitializerTest.kt` to verify the integration is added

**ApplicationStartInfoIntegration.java:**
5. Added `BuildInfoProvider` as a constructor parameter (passed from AndroidOptionsInitializer)
6. Replaced hardcoded `35` with `Build.VERSION_CODES.VANILLA_ICE_CREAM` constant
7. Renamed `trackAppStart()` to `registerAppStartListener()`

**Tests:**
- Updated `ApplicationStartInfoIntegrationTest.kt` to mock and pass `BuildInfoProvider` in all tests
- Added new test in `AndroidOptionsInitializerTest.kt` to verify ApplicationStartInfoIntegration is in the integration list

All tests pass successfully (11 ApplicationStartInfoIntegration tests + 1 AndroidOptionsInitializer test).

**Proposed git commit command:**

```bash
git commit -m "$(cat <<'EOF'
refactor(android): Address review feedback for ApplicationStartInfo

API and code style improvements:
- Mark ApplicationStartInfo API as @ApiStatus.Experimental
- Pass BuildInfoProvider via constructor instead of creating internally
- Use Build.VERSION_CODES.VANILLA_ICE_CREAM constant instead of 35
- Remove redundant version check from AndroidOptionsInitializer
- Rename trackAppStart() to registerAppStartListener()
- Add test to verify integration is registered

All integration tests and unit tests pass.
