Field Notes on Android Platform Engineering Android 平台工程現場筆記
Practical notes on Android BSP, industrial IoT devices, Edge AI platforms, OTA, VPN, diagnostics, and field reliability. 整理 Android BSP、工業 IoT 設備、Edge AI 平台、OTA、VPN、診斷與現場可靠性的實務筆記。
Why Android Devices Still Go Offline Even When the Framework Says Connected Android 顯示已連線，為什麼工業設備還是會失聯？
Industrial unattended devices need more than Android's default network state: they need reachability checks, failover policy, VPN recovery, diagnostics, and field-safe recovery paths. 工業無人值守設備不能只看 Android 的 connected 狀態，還需要可達性檢查、failover 策略、VPN 恢復、診斷與現場恢復路徑。
Why Customers Pay CoreEdge Lab to Maintain the Android Platform Layer 為什麼客戶願意花錢，把 Android 系統層交給我們維護？
The real cost is not maintenance itself, but disconnected devices, failed OTA, unclear ownership, delayed shipment, and field incidents. 真正昂貴的不是維護費，而是設備失聯、OTA 事故、責任不清、出貨延誤和現場派工。
Why Vendor Android BSP Packages Need Heavy Customization for Industrial Unattended Devices 為什麼原廠 Android BSP 需要大幅客製，才能跑在工業無人值守設備上？
A vendor BSP is usually a starting point for development, not a finished platform for unattended industrial deployment. 原廠 BSP 通常只是開發起點，不是可以直接放到現場長時間運行的工業設備平台。
