Add a new function to the MainActivity class called logging() as shown.To learn more, check out the Kotlin documentation on Visibility Modifiers. This means you can also declare a TAG variable for other classes. Even though this variable is declared outside of MainActivity, it's declared as private so that it will only be accessible in MainActivity.kt. Note: The log tag is typically declared outside of the class. In MainActivity.kt, before the class declaration, add a constant called TAG, and set its value to the name of the class, MainActivity.Perform the following steps to start using logging in your blank project. These methods take two parameters: the first, called the "tag", is a string identifying the source of the log message (such as the name of the class that logged the text). There are several functions for logging output, taking the form Log.v(), Log.d(), Log.i(), Log.w(), or Log.e(). In an Android app, the best practice for logging output is using Log class. In the previous lessons, you used Kotlin's println() statement to produce text output. #How to print debug android studio simulatorThe simulator popup a dialog to tell you the android application has been stopped. ![]() Make sure the language is set to Kotlin, and leave everything else unchanged.Īfter creating the project, you'll be greeted with a new Android Studio project, showing a file called MainActivity.kt. When you execute an Android app after coding, you may always meet bellow errors in the android emulator. On the New Project screen, choose Empty Activity.Start by creating a new Android Studio project, as shown. #How to print debug android studio softwareNote: On some Android devices, the Build Number option can be accessed via Settings > About phone > Software information. On the Android device, navigate to Settings > About device, and tap the Build Number option seven times to enable developer mode. Rather than use a large and complex app, we're going to start with a blank project to demonstrate log statements and their usage for debugging.
