LeakLens is a high-performance, professional-grade memory leak detection and fix assistant for Android Studio. It bridges the gap between static code analysis and runtime heap debugging, providing a seamless "detect-analyze-fix" workflow without ever leaving your IDE.
Most tools wait for your app to crash. LeakLens catches leaks before they are even compiled.
Using a high-performance UAST (Universal Abstract Syntax Tree) engine, LeakLens scans your Kotlin and Java code in real-time.
- Write-Time Prevention: 6+ specialized inspections flag leaks (like static Activity references or uncancelled coroutines) as you type.
- Editor Gutter Icons: Visual markers (🚫,
⚠️ ) indicate leaking classes directly in the code gutter. - One-Click Fixes: Use
Alt + Enterto automatically apply industry-standard patterns likeWeakReferencewrapping or lifecycle cleanup.
Integrates the Shark Heap Analysis engine (used by LeakCanary) directly into the IDE.
- SDK-Free Capture: No need to add dependencies to your
build.gradle. LeakLens works entirely via ADB and host-side analysis. - Live Memory Graph: Monitor Java Heap, Native Heap, and PSS in real-time with an integrated lite profiler.
- Auto-Trigger Safeguards: Configure thresholds to automatically dump the heap when your app hits critical memory levels.
