How We Reduced Android App Crashes by 95%
From Production Nightmare to Rock-Solid Stability
Six months ago, our Android app had a 4.2% crash rate. Today, it’s 0.2%. This is the story of how we systematically hunted down and eliminated crashes in a production app serving 300K daily active users. No theory, just battle-tested fixes that work.
The Context:
Crashes aren’t just annoying — they cost users transactions and us revenue. We had to fix this fast, but throwing engineers at the problem wasn’t working. We needed a system.
The Problem: Too Many Crashes, Too Little Data
Our Firebase Crashlytics dashboard was a sea of red. Hundreds of unique crash signatures, thousands of occurrences daily. The VP of Engineering’s question was simple: “Where do we start?”
We had three major problems:
Problem 1: Crash reports were cryptic
Fatal Exception: java.lang.NullPointerException
at com.app.transaction.TransactionProcessor.process(SourceFile:847)Line 847 had 15 possible null references. Which one crashed? We had no idea.
Problem 2: Crashes weren’t reproducible
