### Overview (`README.md`)

# Trinea Android Common

## Overview
Trinea Android Common is a collection of cache components, UI widgets, and utility helpers that power thousands of Android apps. The project focuses on reproducible solutions for list pagination, image/network caching, download management, and day-to-day toolkit gaps so that small teams can ship stable products quickly.

## Modules at a Glance
- **Cache suite**: in-memory/disk image caches, HTTP cache, and preload data cache with FIFO/LIFO/LRU/etc. policies plus persistence helpers.
- **Reusable views**: pull-to-refresh & infinite scroll `ListView`, paged `Gallery`, responsive `ScrollView`, ad/banner carousel, and more.
- **Utility helpers**: `DownloadManagerPro`, shell/package/resource/file/json/string/collection utilities, silent install helpers, time/date helpers, and random utilities used across apps.
- **Dev Tools App**: [Dev Tools on Google Play](https://play.google.com/store/apps/details?id=cn.trinea.android.developertools) lets developers browse the latest OSS projects, inspect activities, decompile APKs, perform color pick, dump manifest info, and toggle developer options quickly.

## Getting Started
1. Import the library module or add the dependency:
   ```groovy
   implementation 'cn.trinea.android.common:trinea-android-common:4.2.15'
   ```
2. Proguard
    ``` xml
    -keep class cn.trinea.android.** { *; }
    -keepclassmembers class cn.trinea.android.** { *; }
    -dontwarn cn.trinea.android.**
    ```   
3. Review the [API Guide](http://trinea.github.io/doc/trinea_android_common/index.html) and [sample app](https://github.com/Trinea/AndroidDemo) for usage patterns.
4. When integrating as a library project, open *Project Properties → Android → Library* and add **TrineaAndroidCommon**.

## Maintenance & Roadmap
Although the codebase has been quiet recently, the components remain in active use across the community. We are preparing modernization work (AndroidX migration, refreshed sample app, expanded tests) and will leverage Claude/Codex for OSS to accelerate documentation, governance, and CI improvements. Community members can watch GitHub Issues/Discussions for upcoming milestones.

# Claude for OSS & Codex for OSS Readiness

## Project Overview
- **Project**: Trinea Android Common (`android-common`)
- **Mission**: provide ready-to-use cache implementations, UI widgets, and utility helpers so Android teams can bootstrap stable apps quickly.
- **Scope**: image/network/cache layers, pull-to-refresh and paging widgets, DownloadManager extensions, shell/package/file/json utilities, etc.

## Governance & Compliance
- **License**: Apache License 2.0.
- **Maintainer**: [Trinea](https://github.com/Trinea); decisions shared via GitHub Discussions, Issue templates, and CodeKK.
- **Contribution flow**: Fork → feature branch → PR with CLA confirmation → unit tests/static analysis → review → merge.
- **Distribution**: Gradle/Maven Central (`cn.trinea.android.common:trinea-android-common`) plus Dev Tools App scaffolds.

## Impact
- Used by thousands of domestic and international apps, 5k+ GitHub stars.
- Referenced by InfoQ, GeekTime, and enterprise templates to teach caching/tooling patterns.
- Maven Central downloads historically exceed 100k/month, validating real-world demand.

## Claude for OSS Plan
1. **Docs modernization**: Claude helps refresh multilingual README/API guides and migration docs.
2. **Issue triage**: summarize duplicate issues, propose first-pass diagnostics, and improve response quality.
3. **Knowledge transfer**: generate design docs/comments so new maintainers can onboard faster.

## Codex for OSS Plan
1. **AndroidX migration**: Codex assists with scripts that port legacy support APIs to AndroidX and upgrade AGP/Gradle.
2. **Test coverage**: auto-generate unit/instrumentation tests for caches and utilities.
3. **Performance insights**: use Codex to script benchmarks/LeakCanary configurations and analyze regressions.

## Responsible AI Use
- Every AI-assisted change is reviewed and annotated in PRs/releases.
- Sensitive logs or proprietary data are never uploaded; data is anonymized when needed.
- Rollback mechanisms and audit history ensure traceability.

## Support Needs
1. Align modules with AndroidX + Kotlin best practices and publish a refreshed release.
2. Raise test coverage above 50% and add benchmarking.
3. Update samples/docs with modern Compose-centric guidance.
