## What it is
MethodTraceMan is an Android performance tool that finds high time-consuming methods causing app jank via bytecode instrumentation. It uses a Gradle plugin with ASM to instrument methods at compile time and displays method timing data in a browser UI with filtering by time, thread, and method name.

## Use cases
- find slow methods causing Android app jank
- trace method execution time via bytecode instrumentation
- profile Android app performance during development
- filter method timings by thread or duration
- instrument only specific packages with a Gradle plugin

## When to choose
- debugging Android app stutter and frame drops during development
- you want configurable method-level timing without manual code changes
- you prefer a visual UI to browse method cost data

## When to avoid
- production profiling (release builds use a noop dependency)
- iOS or non-Android projects
- projects needing actively maintained tooling or a licensed release

## Facets
- artifact type: library
- maturity: maintenance
- function: monitoring, benchmarking, developer-tools
- domain: android-tools, performance, developer-tools, mobile-development
- platform: jvm, cli
- tags: android, method-tracing, jank-detection, asm-instrumentation, gradle-plugin, bytecode-instrumentation, performance-profiling
