Crash Reporting & Store Release is a free Kotlin Multiplatform Academy lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Kotlin Multiplatform Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Crashes Will Happen
Even great apps crash on real devices. A crash reporter tells you what broke and where, instead of leaving you guessing from reviews.
Pick a Cross-Platform Tool
Tools like Crashlytics or Sentry have Android and iOS SDKs, so you can monitor both apps from one familiar dashboard.
Initialize on Each Platform
The reporter lives in native code. Initialize it in the Android app and the iOS app, not inside your shared commonMain module.
Report from Shared Code
Expose a tiny expect/actual logger so shared code can record handled errors that each platform forwards to its native reporter.
expect fun logError(t: Throwable)Read Native iOS Stack Traces
Kotlin/Native crashes appear with native frames. Uploading dSYM files lets the reporter symbolicate them into readable function names.
Add Breadcrumbs
A bare stack trace lacks context. Logging breadcrumbs of recent actions helps you reproduce the exact path into a crash.
Bump the Version
Before release, raise the version and build number. Stores reject duplicates, and crash reports group cleanly by version.
Release the Android App
Upload the signed app bundle to the Play Console, roll out to a test track first, then promote to production once it looks healthy.
Release the iOS App
Archive in Xcode, upload to App Store Connect, test through TestFlight, then submit that same build for App Store review.
Watch the First Hours
Right after launch, watch your crash-free rate. A sudden dip means roll back or ship a fast fix before more users are hit.
Close the Loop
Treat crash data as a backlog: triage top issues, fix them in shared or native code, and confirm the rate climbs in the next release.
Quick Check
Recall what makes iOS crash traces readable.
Recap
You wired a cross-platform crash reporter, bridged logging from shared code, uploaded dSYMs, released to both stores, and watched the crash-free rate. 🚀
