Paste a crash or ANR stack trace to get a readable breakdown — the exception, the root cause, and the most relevant app frames. Paste your crash or ANR stack trace in your browser to view the relevant details; results reflect what you paste.

About Crash / ANR Analyzer
Paste a crash or ANR stack trace to get a readable breakdown — the exception, the root cause, and the most relevant app frames.
Crash / ANR Analyzer is part of APKLint’s code quality toolkit — Static analysis for Kotlin, Java, and your Gradle build. It’s free to use and needs no account.
Your privacy is the default: what you submit is processed on our servers over an encrypted connection for that request only — it isn’t written to file or object storage, and never shared.
What Crash / ANR Analyzer checks
- Identifies the exception type and message
- Highlights the most relevant app frames
- Separates framework frames from your code
- Gives a readable summary of the stack
Good to know: Works on the trace text you paste. It does not de-obfuscate using a ProGuard mapping file or parse native tombstones.
When to use Crash / ANR Analyzer
- Best for
- Pasting a crash or ANR stack trace to get a readable breakdown, the exception, the likely root cause, and where to look.
- Not the right tool for
- Not a binary analyzer and not a live profiler.
- What you get back
- A parsed trace: the exception type, the probable root frame, and a plain-language explanation.
- How it differs from related APKLint tools
- It is the runtime-failure tool, unrelated to the static APK and code analyzers, focused on logs you already have.
- Limitations
- It reads the trace you paste; without symbols, obfuscated frames stay opaque.
