Overview of the sample project

- [Voiceover] Before we get started coding our sample app,…let's take a look at the finished app…to see what we will be building.…I've started my virtual device simulator and have launched…the finished version of the app in the Debugger.…Our sample app will exercise a few different parts…of Firebase: analytics, remote config, and authentication.…The application contains three different activities.…The main activity contains a few buttons to demonstrate…how to record different kinds of events as analytics events.…

Events will be recorded when the user clicks…on these two top buttons,…even though they don't actually do anything in the app.…There's also a button to launch the sign in activity.…The sign in activity will be used to demonstrate…how to implement Firebase authentication.…In this case, we're going to build support…for email and password authentication.…We'll see how to create new accounts,…sign the user in, and sign the user out.…We'll also see how to detect different kinds…of authentication errors and report them to the user,…
