The debugger watch area is a powerful tool, it's worthy of two lessons in the course. If you don't know about Object Marking you need to see this!

There are several factors to cause apps to crash on your Android smartphones. Sometimes one or several bugs are responsible for crashing the apps.

Learn about tracepoints (AKA logpoints) how exception breakpoints don't have to suck, watchpoints, filters & why method breakpoints are problematic.

Stop digging through variables in the watch to find nuggets of gold, or rerunning the expression evaluation. Use entity renderers instead.

This isn't just about memory leaks. Understanding how RAM is used and its content provides insight into the app you can't get in any other way!

Debugging over the network using a protocol like JDWP isn't hard. However, there are risks that aren't immediately intuitive and some subtle solutions

Playwright Test for VSCode allows you to install Playwright in your projects or add new browsers configuration, but today the goal is the debug.

Does your application fail CI tests "sometimes"? Does it display flaky behavior? Did you add many logs trying to solve it? There's a better way: AOP!

Applications fail, that's inevitable. All the testing, QA, CI and defensive programming can make this a rare occurrence, but can't eliminate failure.

What do you do when you have a bug? Using a well defined process instead of looking everywhere, can significantly change the issue resolution process.

"It works on my machine" is never an excuse. Sometimes we have bugs that we can't reproduce or understand. How do we investigate these elusive bugs?

Delve into a two-pronged strategy that streamlines debugging, enabling developers to swiftly pinpoint and resolve elusive software glitches.

Explore the academic theory of the debugging process, focusing on issue tracking, team communication & the balance between unit to-integration tests.

Master the art of debugging with strategies like Rubber Ducking, leveraging tools, and systematic checklists. Turn challenges into rewarding puzzles!
