android studio debugging stops working with proguard

Breakpoints step through code one line at a time without the need to add log statements and re-running your app first. That bug was found and fixed by examining the stack trace, and this assumption was verified using log statements.Īs you're already familiar with that example, it will be used to demonstrate how breakpoints can be used. Remember the division by zero example from the debugging lesson in Unit 1? On the final iteration of the loop, when the app attempts to perform division by zero, the app crashes with a java.langArithmeticException, because division by zero is impossible. You'll be greeted with a new Android Studio project, showing a file called MainActivity.kt.Name the app Debugging, make sure the language is set to Kotlin, and everything else is unchanged.On the Select a Project Template screen, choose Blank Activity.Start by creating a new Android Studio project. Rather than debugging a large and complex app, we're going to start with a blank project and introduce some buggy code to demonstrate the debugging tools in Android Studio. A computer with Android studio installed.Add variables to the Watches pane to aid with debugging.Add conditional expressions to breakpoints to save time debugging.Use breakpoints to pause a running app and inspect the code one line at a time.How to attach the debugger to your running app.You know how to navigate a project in Android Studio.You'll also learn how to use a feature called Watches, and track specific variables instead of having to add specific log statements. In this lesson, you'll learn about Android Studio's integrated debugger, how to pause execution of an app, and how to execute single lines of code at a time to pinpoint the exact source of the bug. While these are both powerful debugging tools, modern IDEs provide more functionality to make your debugging process more efficient. If you've completed Unit 1, you'll also be aware of how to read stack traces and research error messages. keep class * extends until this point, most beginning developers will probably be aware of debugging with Log statements. The mapping file is also generated, but has no text in it. The following files are generated each time I create a build: seeds.txtĪll of the files, except the mapping.txt, are being generated properly each time the build is created. The file used to be generated properly each time I created a build. In the last week, the Proguard mapping.txt file is suddenly being created as an empty file (0 KB) for all of my Android Studio projects.
