🤖 Android RCA Analyzer

AI-powered Android Defect Root Cause Analysis Tool
Built for Senior QA Architects, Framework Engineers & Android Debug Specialists

---

🎯 What It Does

A single-file, browser-based tool that accepts Android bug reports and diagnostic artifacts, then uses Claude AI to produce a complete 8-step Root Cause Analysis in seconds.

8-Step Investigation Flow

Step	Description
1️⃣ Categorize Defect	Crash · ANR · Camera Failure · Performance · Battery · Memory Leak · Thermal · UI · Connectivity · Sensor
2️⃣ Log Analysis	Exception type · Stack trace · Error codes · Thread info · Process name
3️⃣ Framework Mapping	Application → Framework → HAL → Kernel → Vendor → Driver layers
4️⃣ Root Cause	Immediate cause · Underlying cause · Trigger condition · Dependency failure
5️⃣ Confidence Score	High (>90%) · Medium (70–90%) · Low (<70%) with reasoning
6️⃣ Fix Recommendation	Developer fix · Config fix · Workaround · Validation plan
7️⃣ Risk Assessment	Severity · Customer impact · Production risk
8️⃣ Automation	Suggested regression, smoke, stress, monkey test cases

ROOT CAUSE ANALYSIS
Primary Cause    | Binder thread pool exhaustion in CameraService
Secondary Cause  | Upstream HAL callback timeout not handled
Confidence       | High · 91%

FIX RECOMMENDATION
Developer Fix    | Increase binder thread pool size, add timeout handler
Workaround       | Force-stop camera app, clear cache

AUTOMATION TESTS
1. [Regression] Camera Launch Stress Test
2. [Monkey]     Random camera gesture stress under low memory
3. [Regression] ANR detection on camera open/close cycle
