About this app

LogCat Analyzer is a mobile debugging toolkit that turns raw logcat files into actionable insights. Import .logcat files exported from Android Studio and instantly detect crashes, performance issues, and bugs — right from your phone.

▶ INTELLIGENT ISSUE DETECTION
Import a logcat file and the app automatically scans for 6 types of issues:
• Crashes — NullPointerException, IndexOutOfBounds, Fatal Signals with full stack traces
• ANR — Application Not Responding with root cause identification
• Memory Pressure — GC thrashing, low memory warnings, OutOfMemoryError
• Network Errors — timeouts, DNS failures, SSL errors, HTTP 4xx/5xx
• StrictMode Violations — disk/network on main thread, dropped frames
• Infinite Loops — repeated error patterns and retry storms

Each issue includes a severity badge, occurrence count, root cause explanation, and a suggested fix.

▶ EXPLAIN & FIX
Tap any detected issue to get a detailed explanation:
• What happened and why
• Likely root cause based on stack trace analysis
• Step-by-step suggested fix
• One-tap Google search or AI assistant for deeper help

▶ CRASH ANALYSIS
• Visual crash timeline with expandable stack traces
• Crash summary with severity assessment (Low → Critical)
• Group crashes by exception type with occurrence counts
• Copy stack traces or export crash reports

▶ INSIGHTS DASHBOARD
• Log level distribution chart
• Device metadata — model, OS version, serial number, emulator detection
• File overview with error and warning counts
• Quick navigation to crash timeline and summary

▶ LOG EXPLORER
• Smart context-aware highlighting: red for crashes, blue for lifecycle, yellow for warnings, cyan for network calls
