Android local-network regression scanner
Build a developer tool that scans Android projects for upcoming permission and networking regressions related to local network access. It would catch missing declarations, runtime permission flows, and hostname-to-private-IP edge cases before release.
为什么这很重要
You maintain a small Android companion app for a home service, and everything seems fine until a target SDK bump or phone update causes local connectivity to break. Users report that the app cannot reach their LAN device, but nothing obvious in your logs points to the real cause. Because the issue is tied to evolving platform permissions and subtle networking rules, you can ship a release that looks healthy in basic testing yet fails in production. A pre-release scanner that flags risky permission gaps and local-address access patterns would save you from support tickets, bad reviews, and hours of post-release debugging.
- · 专为 Maintainers of Android apps that connect to self-hosted services, home automation systems, NAS devices, or LAN-only APIs. 打造。
- · 最可能的变现方式：SaaS subscription。

为什么这件事可能失败
自我反驳——最重要的信任度信号
- 1The user base may be too niche and too accustomed to free tooling to support SaaS pricing.
- 2Developers may rely on existing lint tools and documentation instead of adding another CI product.
- 3The most painful failures may require runtime simulation, reducing trust in a mostly static scanner.
证据综述
AI 如何合成此洞察——无原话引用
Several commenters framed the core issue as a developer-side miss rather than a platform defect, which supports a tooling opportunity aimed at maintainers. Multiple people referenced SDK bumps, missed documentation, and insufficient testing, while others highlighted that the underlying permission model is acceptable. That combination suggests demand for software that prevents release mistakes rather than software that bypasses platform rules.
