In Android Studio, selectFile > New > Import Project.
Go to the location where you saved the repository and select the project directory for
Kotlin or Java:
Kotlin:PATH-REPO/android-samples/ApiDemos/kotlin
Java:PATH-REPO/android-samples/ApiDemos/java
SelectOpen. Android Studio builds your project, using the Gradle build
tool.
Create a blanksecrets.propertiesfile in the same directory as your project'slocal.propertiesfile. For more information about this file, seeAdd your API key to the project.
