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.

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.

Model Context Protocol allows AI models like Claude to communicate with the outside world. But MCP debugging has been one of our steepest learning curves at Bugfender. Several different layers need to work together at the same time and if one thing breaks, it can scupper the whole workflow. That’s why we’re here today. To pass on hard-won knowledge, so you can jump the curve.

An effective Java debugging strategy lets us pause execution, inspect data, and observe real execution rather than relying on vague assumptions. The complexity of the Java Virtual Machine creates unique challenges, but a focused approach will turn this complexity to our advantage. This guide will equip you with the tools to do this, looking at: By the end, you’ll have a practical workflow to debug Java reliably across local and remote environments.

Node.js debugging allows us to identify and fix errors, unexpected behavior, and performance issues in server-side JavaScript applications. Instead of using the less precise console.log, we can connect a real debugger and control execution step by step. Most Node.js developers actually use one of two distinct setups: This guide will show you how to use both technologies, with a clear step-by-step workflow for each.

React Native debugging poses particular challenges due to the framework’s cross-platform codebase, which combines JavaScript and native platform components. However, an effective React debugging regime will enable you to proactively fix issues in both production and development. Today’s post will give you the fundamentals to build that regime, showing you: Want to jump to a specific bit of knowledge? Here’s the full list of contents.

JavaScript dates look simple until they’re not. Here’s the second way to create a date: pass the components manually. Year, month, day, hour, minute—each as a separate number. And anything you skip defaults to zero. So you can write just the year, month, and day like this……but there’s a catch coming.

Learn how to use the JavaScript Date object, format dates correctly, handle timezones, and avoid common bugs with the Date and Time API. This 2025 guide covers parsing, formatting, new date formats, and everything developers need to work reliably with date and time in JavaScript. If you’ve ever seen a date shift by one day, hours changing unexpectedly, or confusing “Invalid Date” errors… this tutorial will finally make it all make sense.

Bugfender is a modern remote logger tailor-made for mobile development.
Most developers debug their apps by looking at the logs generated by their application. Usually this means connecting the mobile device with a debugging cable and looking into NSLogs or logcat.
Bugfender is a cloud storage service with an easy to use SDK that lets developers send their application logs for later use. Works for early development phases, beta testing and production applications. Bugfender unlocks the possibility to detect errors earlier, assist better users who contact your customer support and ultimately achieve an excellent customer satisfaction.
Bugfender represents a new opportunity, log collection services have existed for years on the back-end and network monitoring industry but never applied yet to mobile devices.
