Android App Crashes: Causes, Detection, and Fixes

Android app crashes will cost us users and damage our Play Store ranking. To prevent them from happening, we need to understand the most frequent causes of crashes, read the stack trace effectively, and have plans for common painpoints such as null values. This article will give you the tools to do that.

JavaScript Debugging: the Complete Guide

An effective JavaScript debugging process is vital for any web developer. Over 95% of the web is built with JavaScript code, but the language carries its own distinct challenges due to its unique runtime model. This guide will help you master these challenges and become truly fluent in the Internet’s first language. You’ll learn about: You’ll leave with a process that works in any case, no matter how edgy.

Swift Arrays: Complete Guide to Sort, Filter, Map and Reduce

Swift arrays are one of the most commonly used collection types in iOS and macOS development. They provide ordered, type-safe storage for values and include powerful higher-order functions such as map, filter, reduce, and sort. With value semantics, copy-on-write optimisation, and a rich set of built-in operations, Swift arrays make it easier to write safe, efficient, and expressive code. This guide will empower you to master the basics of Swift arrays and explore all the functionality they provide.

React Native OTA updates: Bitrise CodePush demo

From our CodePush webinar: a practical walkthrough of setting up and managing CodePush for over-the-air (OTA) updates on Bitrise using a React Native application. Staff Solutions Engineer Atanas Chanev shows you how updates are handled by pushing a direct update via the command-line interface, promoting a staging release to production, and executing an emergency rollback to a previous version using the API.

The mobile gap: Vision-based testing catches what code reviews miss

The pull request looked perfect. Two approvals, clean diff, all checks green. The team shipped it Thursday afternoon. By Friday morning, support tickets were coming in. On a popular mid-range Android device, the new checkout button rendered behind a promotional banner: visually present but physically untappable. Every reviewer read that code, yet none of them could have caught it, because the defect was never visible in the diff. It only ever appeared on the device.

Mobile test recording just got a lot less painful (Studio 11.4) #Katalon #MobileTesting #QA

Mobile Recorder Interactive Mode is now official in Katalon Studio 11.4. Interact directly on the device view and Studio reflects exactly what you're doing. Select an object in Device View, and your test steps follow that selection automatically. We've also improved the action flow so common recorder tasks feel more natural inside your session. Less guesswork. Faster mobile testing. Tell us in the comments which feature you want covered in next month's update.

Android App Crashes: Causes, Diagnosis, and Fixes

Android app crashes are a nightmare for developers. But they rarely come out of the blue. Most crashes stem from structural causes like leaky memory or sloppy resource management, and most failures will have a root cause that surfaces in either logcat or the stack trace. This post will give you a true Android crash course, showing you the tell-tale signs and the tried-and-tested fixes that work across devices, territories and app utilities.

Your Mobile Tests Just Got a Lot Less Repetitive | What's New in Katalon Studio | Give It a Test

Katalon Studio's latest update is out. Sơn Huỳnh (Support Engineer, Katalon) walks through what's new in Katalon Studio 11.3 and 11.4 — from a faster, more direct Mobile Recorder to saving your AI-generated API tests straight into the repository.

AI Debugging: How to Use AI to Find and Fix Bugs Faster

At its simplest, AI debugging automates repetitive coding tasks like searching logs, reading stack traces and comparing sessions. But good AI debugging is a much more challenging concept that relies on focused context, runtime evidence and structured investigation paths. In this post we’ll show you how to debug with AI, not just productively but also responsibly. Let’s get into it.

How can AI agents reduce operational costs throughout the organization?

‍ Every CFO has looked at the headcount report and asked the same question. Why does it take twelve people and four tools to do something that feels, on paper, like it should take three? The honest answer is usually not laziness or bloat. It is a coordination tax. Someone has to read an email, decide what it means, open three other systems to check context, type a response, update a tracker, and notify two other teams. None of that is hard work.
