Samples
You can open each of the following samples as an Android Studio project, and run them on a mobile device or a virtual device (AVD). When doing so you need to add each sample app you wish to try to a Firebase project on the Firebase console. You can add multiple sample apps to the same Firebase project. There's no need to create separate projects for each app.
To add a sample app to a Firebase project, use the applicationId value specified
in the app/build.gradle file of the app as the Android package name. Download
the generated google-services.json file, and copy it to the app/ directory of
the sample you wish to run.
