Kotlin Debugging Made Simple: All Your User Session Data, One Interactive View

Written by Miguel Valdes Faura | Jun 16, 2025 11:24:11 AM

Debugging Kotlin apps just got a bit simpler. We've rolled out an updated Timeline View in the Kotzilla Console that puts every piece of session data you care about onto one interactive screen. Here’s why you should check it out:

Meet the Interactive Overview Slider

First thing you’ll notice: an overview slider right at the top. It shows a clear visual timeline of key moments in any user session recording:

  • Screen transitions

  • Crashes

  • Detected issues

Want more detail? Zoom in on any part of the slider, and watch how the panels below instantly update to show that exact slice of the user session.

 

Dig into Session Activity Graphs

On the left side, you’ll find two key graphs plus useful metadata tabs:

  • Dependency resolution graph
    Tracks requested vs. created dependencies over time. You’ll spot spikes or gaps at a glance.

  • Thread execution timeline
    Maps key events and component resolutions across main and background threads, helping you identify performance bottlenecks or threading hiccups

  • Tabs for extra context

    • Session Summary: Device model, OS version, app version, session timestamp

    • Session Properties: Any custom properties you’ve added using the Kotzilla SDK API such feature flags, user preferences, or other metadata

 

Explore Detailed Event Insights

On the right, it’s all about specifics:

  • Full sequence of events
    See every component and dependency resolution event, complete with metadata.

  • Linked issue flags
    Any performance, architectural issues, or crashes detected in your app appear right next to the related component or dependency


  • Tree graph view
    Visualize dependency hierarchies and instantly spot which classes are taking the longest to resolve.

Instant Context from Your Issues View

Here’s a neat shortcut: when you click a specific user session from the Issues View, the Timeline opens focused on the exact moment the issue occurred. No hunting around, no manual searching, just instant, precise context of app issues.

Log in to the Kotzilla Console, open the Timeline View, and start zooming, clicking, and investigating, all in one place.

We think you’ll find root-cause analysis faster and more intuitive than ever. If you run into any questions or have feedback, drop us a line at support@kotzilla.io.

Happy debugging!
