Get started with Bugsnag and Kotlin in minutes
Setup is quick using our Android or Java SDK. Thanks to Kotlin being 100% interoperable, you can leverage our Android and Java libraries and immediately begin detecting bugs in your Kotlin application.
Proactively improve software quality
Visibility into errors is only the first step. With two-way integrations and in-app workflow, you'll also make progress prioritizing bugs and moving them through your debugging process.
Prioritize bugs with the greatest user impact
See which crashes happen most and which affect the most users, so you can assess a crashes' impact and prioritize your work.
Benchmark releases to improve app health
Use the Releases dashboard to decide if a release is successful or needs to be rolled back. The crash rate indicator shows the percentage of sessions in a release that end in a crash, allowing you to compare release health and track improvements over time.

Investigate Kotlin app crashes
Tests aren't enough to keep your app crash-free. Device fragmentation and environment differences impact how your app runs.
Diagnostic error data from device
Avoid one-star reviews
Users who have negative experiences using your app can leave negative reviews. Avoid these by staying ahead of bugs and releasing quality code.
See where your app is running
Crash reports include device manufacturer, model, and OS name and version to help you understand if crashes are widespread or isolated to a specific device.
See the state of the device
Debugging is easier when you know the state a device was in during a crash. Bugsnag reports details on memory, hardware features, other apps open, rooted, permissions, battery, and more.
Identify crashes from other sources
Bugsnag lets you know when severe crashes are caused by backend or API changes, and alerts you to spiking error rates. You can even snooze alerts until they reach a critical level.

In-depth Kotlin exception reports
Automatically captured reports give you the answers you need to pinpoint the source of errors
Kotlin stacktrace
See the code that crashed
See the full de-obfuscated stacktrace for each exception, even full thread state information. If you're using ProGuard on Android, our Gradle plugin uploads your mapping files for each build so you can see the line of code that crashed.
See automatic breadcrumbs
Bugsnag automatically captures breadcrumbs, a timeline of navigation events and system broadcasts leading up to the crash being detected. Use them to easily reproduce crashes.
User information
Every exception is tagged with user details so you can correlate errors with customer support requests.
Mobile specific diagnostics
Exceptions on mobile require special context, like the screen open when a crash happened and out of memory errors.
