Code Review for PR #421: Restore min SDK 23

I've reviewed the changes in this PR. Here's my comprehensive feedback:

Summary of Changes

• app/build.gradle: Changed minSdkVersion from 24 to 23
• .github/workflows/build_test.yml: Re-enabled testing on API levels 29, 30, and 32 (previously commented out)

Review Feedback

✅ Positive Aspects

1. Restoring API 23 support increases device compatibility, allowing the app to run on more Android devices
2. Re-enabling multiple test API levels (29, 30, 32) improves test coverage and helps catch potential issues across different Android versions

⚠️ Concerns and Issues

1. Test Failures

The PR description states "none of our tests are passing right now". This is a critical issue that needs to be addressed:

• The tests may be failing due to API 23 compatibility issues
• Re-enabling tests on multiple API levels without fixing underlying issues won't help
• Recommendation: First fix the tests on a single API level before enabling more

2. API Level 23 Still Disabled in Tests

I notice that API level 23 tests remain commented out in the workflow file:

# broken for unknown reasons. needs some offline debugging
# https://github.com/opendocument-app/OpenDocument.droid/issues/390
# - { arch: x86_64, api-level: 23 }

• If you're restoring min SDK to 23, you should also ensure tests pass on API 23
• The linked issue API 23 test broken #390 should be investigated and resolved
• Recommendation: Fix API 23 tests before merging this change

3. NDK Version Mismatch

The project documentation (CLAUDE.md) states NDK version 26.3.11579264 is required, but:

• The workflow uses NDK 28.1.13356709
• app/build.gradle also specifies NDK 28.1.13356709
• Recommendation: Update CLAUDE.md documentation to reflect the correct NDK version

🔒 Security Considerations

• No security concerns with these changes

🚀 Performance Considerations

• Supporting API 23 may require additional compatibility code that could impact performance
• Ensure any API 23-specific workarounds don't negatively affect performance on newer devices

🧪 Test Coverage

• Critical gap: No tests running on the minimum supported API level (23)
• This creates risk of shipping code that breaks on API 23 devices

Recommendations

1. Fix the failing tests first - The PR should not be merged with all tests failing
2. Enable API 23 tests - Since you're supporting API 23, you must test on it
3. Update documentation - Correct the NDK version in CLAUDE.md
4. Consider a phased approach:
   • First, fix tests on the current min SDK
   • Then restore API 23 support with working tests
   • Finally, re-enable additional API level tests
