39.2 Adding Navigation to the Build Configuration

A new Android Studio project does not, by default, include the Navigation component libraries in the build configuration files. Before performing any other tasks, therefore, the first step is to modify the app level build.gradle file. Locate this file in the project tool window (Gradle Scripts -> build.gradle (Module: app)), double-click on it to load it into the code editor and modify the dependencies section to add the navigation libraries:

dependencies {

    implementation 'androidx.navigation:navigation-fragment:2.0.0'

    implementation 'androidx.navigation:navigation-ui:2.0.0'

.

.

}

Note that newer versions of these libraries may have been released since this book was published. To identify and use newer versions of the libraries, add the above lines to the build file and then open the Project Structure dialog (File -> Project Structure...)...
