This can be a really frustrating scenario, since it gives you very little information to go off of at first glance. Using console.log for debugging isn't considered the best practice, but it's fast, easy, and oftentimes provides some illuminating information Use breakpoints (or console.logs) to check and make sure a certain piece of code is being run, or that a variable has a certain value.This should narrow down the possible sources of the error, and provide you with more information to search the internet for others who have had the same problem.For example, if you use a state management library like Redux, you can try removing that from the equation completely to see if the issue lies in your state management (which is really common in React apps) If the code you're adding in each "piece" is complex, you may want to simplify what you're doing.Apply your recent changes piece by piece, until it breaks.Revert back to a working version of your code (this may even be a completely blank npx create-expo-app project).This step is vital in fixing obscure errors.
Isolate the code that's throwing the error.
Search for the error message in Google and Stack Overflow, it's likely you're not the first person to ever run into this. For errors that aren't as intuitive to solve, here's a good list of steps to take: Let's walk through using the debugger in Android Studio, to familiarize ourselves with this process and make future bugs easier to track down and address.Sometimes you'll be able to tell exactly what's wrong just by the stack trace, but other times the error message is a little more cryptic. It allows us to monitor our application in real time, and can provide additional insight regarding a connected device or emulator. Similar in name, the Android Studio version is also called the debugger. It can pause code, allow us to walk through code line-by-line, check what variables are, and more. This process is similar to using the console.log() method we learned in JavaScript, but with a few expanded options and functionalities.ĭo you remember using the JavaScript console and debugger in Intro to Programming and JavaScript? Android studio also offers a feature like this to assist in tracking down bugs and other issues. In the last lesson we learned about the Android Studio logcat, and how to record information to it using various Log methods.
