An effective JavaScript debugging regime is essential if we want to build responsive, reliable and highly-rateable Android apps. JavaScript doesn’t enforce types at compile time (unlike Swift) and this means errors often happen quietly, when users are already feeling them. So it’s vital that we debug pre-emptively, using knowledge rather than guesswork.

Custom logging can technically capture everything, but in practice, it rarely does. Coverage degrades over time, external APIs get forgotten, and during incidents, you're left asking "did anyone log this?" instead of debugging. Automatic capture solves this. If you're a technical leader, there's a good chance your team is spending significant time on custom logging… and you might not even realize how much it's costing you in productivity and incomplete debugging data.

Kotlin annotations allow compilers or libraries to understand our code. These metadata tags don’t directly change code logic, but they help modify how it is interpreted, optimized, or validated. This simplifies Android development by automating repetitive tasks and ensuring consistent code behavior. It also improves code readability, reduces boilerplate code, and introduces automated checks and generation.

Remote debugging is the most reliable way to grasp what’s really happening inside a mobile app once it’s out in the wild. We’re talking crashes that never appear in development, and issues from users that can’t be reproduced locally. If you ship mobile apps, you’ve been vexed by these problems at some point.

Heroku's logging system is your primary window into application behavior, but its ephemeral nature and streaming architecture can feel mysterious at first. This guide walks through everything developers need to know about Heroku logs, from understanding what they are and how to access them, to working around their limitations and forwarding them to external services like Honeybadger Insights for complete observability. Read on to master Heroku logging.

Chrome developer tools, or Chrome DevTools, give us a window on how our websites working in the wild. Built for developers of all experience grades, they provide powerful ways to inspect, debug and optimize our projects. However the sheer breadth of functionality can be a mind-melt if you’ve not worked with DevTools before, and there are lots of advanced features that even experienced users find tricky.

iOS code signing is a critical step in app development, ensuring apps are secure and trusted by Apple and users. However, it often leads to frustrating errors that can disrupt development and delay app launches. Here’s what you need to know.
