Summary

  • Android 17 build logs no longer contain build <product>/obj/NOTICE.*, so the Notice column stayed empty.
  • Also accept Install: lines for on-target notices. The filename may be NOTICE.xml, NOTICE.html, or NOTICE.txt, with an optional .gz.
  • Read each installed file by itself. Do not scan system/etc, which contains unrelated xml files.

Test plan

  • Android 16 log that still has build .../obj/NOTICE.html (or .xml / .txt / .gz) still fills the Notice column.
  • Android 17 log with Install: out/target/product/<product>/system/etc/NOTICE.xml.gz fills the Notice column from that file.
  • A log with Install: paths for NOTICE.html.gz and NOTICE.txt is picked up the same way.
  • fonts.xml next to system/etc/NOTICE.xml.gz is not treated as a notice index.
  • Confirm the analysis log prints Notice file from build log (Install): ... instead of Notice file not found.

Android 17 logs partition NOTICE files as Install paths, and the
filename may be xml, html, or txt with an optional .gz.

📝 Walkthrough

Walkthrough

Android build-log parsing now collects installed NOTICE paths and reads them individually. NOTICE discovery and loading support TXT files, gzip input, and multiple text encodings. Legacy NOTICE paths and the existing fallback remain supported.

Changes

Android NOTICE handling

Layer / File(s) Summary
NOTICE discovery and file loading
src/fosslight_android/check_notice_file.py
NOTICE discovery now includes qualifying TXT files and recognizes compressed XML, HTML, and TXT files. The shared loader handles gzip input, encoding attempts, and XML or HTML parsing. read_single_notice_file loads one specified file without scanning its parent directory.
Build-log NOTICE path integration
src/fosslight_android/android_binary_analysis.py
Build-log parsing collects distinct installed NOTICE paths and sets a legacy path only once during reverse traversal. The obj fallback applies only when neither source provides a path. NOTICE loading reads legacy paths with read_notice_file and installed paths with read_single_notice_file, then merges mappings and unique file paths.

Estimated code review effort: 3 (Moderate) | ~20 minutes

304-306: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

A legacy path found in an earlier reversed line can be mixed with a stale build_out_notice_file_path value.

build_out_notice_file_path is a module-level value. The check not build_out_notice_file_path is evaluated against the previous state, not per run. set_env_variables_from_result_log resets installed_notice_paths but does not reset build_out_notice_file_path or build_out_path. A second call in the same process keeps the first result. The tool calls the function once per run, so the impact is low. Reset both values at the start of the function if the function may be reused.

304 - 306:
Reset build_out_notice_file_path and build_out_path at the start of
set_env_variables_from_result_log so each invocation derives these values from
the current result log rather than retaining state from a previous call.
