In Android, How Does Firebase Work? (Tutorial)

If you're already familiar with Firebase? Let's take a look at how Firebase functions in Android, as if it were a pizza in Firebase's stomach.

Firebase Work Android

Firebase is a backend service for mobile and web apps that includes a number of important features such as:

  • Hosting
  • Authentication
  • Push Notification
  • Executing A/B testing

And there's a lot more to Android, iOS, Unity, and Web apps.

But, in this article, we'll look at how Firebase works in Android. What problems can it answer for us, and how can we bring it to Android?

By Creating A Firebase Environment, You Can Learn How Firebase Works

As a result, we'll require an Integrated Development Environment, or IDE, to use Firebase in our Android project.

There are various IDEs for developing Android apps, such as Xamarin, Visual Studio, and Eclipse, but we'll choose "Android Studio," which Google recommends.

To begin, you must first download and install Android Studio, which is available for both Mac and Windows.

You can download it from its official website.

I won't go into detail on how to instal Android Studio because it's very self-explanatory and documented on their website.

Before downloading this 700 MB file, please review the system requirements.

After you've downloaded and installed the software, you'll need to build an Android project, which involves the steps below:
  • Choosing a project - you can choose any activity, and the code for that activity will be available when the project is formed. You must select the Empty Activity.
  • Set up your project by giving it a name, a package name (which must be unique), saving the location and language, and clicking the Finish button. You must leave all of the default settings for this presentation.
Remember that if this is your first project, it will take a few minutes or longer.

We're not here to learn how to code; instead, we're here to learn how Firebase works in Android, right?

As a result, we'll get right into it.

Android Studio integration with Firebase

Google's Firebase and Android Studio (also known as Android OS) are designed to function together as a family.

In Android Studio, there are two ways to incorporate Firebase.

1. The Plugin Method (Easiest one)
2. The Manual Method (Full of hassles)

Firstly,

Step 1 - Open your Android Studio project in a new window.

Step 2 - Select Firebase from the menu's Tools section.

Step 3 - On the right side, you'll find a window that lists all of Firebase's services.

Step 4 - Choose an option that suits your needs; for example, I'm interested in Firebase Analytics, therefore I'll select the option "Log an Analytics Event."

Step 5 - Now, regardless of which package you want to utilise, the first step is to link your project to Firebase. To do so, you'll need to use your Gmail account to log into Android Studio. Otherwise, it will lead you to a browser that will prompt you to log in.

Step 6 - Once you've logged in, you'll be asked to connect to an existing Firebase project or create a new one. After that, click the "Connect to Firebase" button at the bottom to connect to Firebase.

Step 7 - Implementing libraries in the build.gradle file, downloading the JSON file from Firebase, and then syncing the project will take some time.

Step 8 - Your project will be connected to Firebase after it is finished. Now you can use any Firebase product you've ever wanted.

Step 9 - As I picked Firebase Analytics, you can see a button that says "Add Analytics to your app." The instructions for all products are offered immediately in that pane. The remainder of the products are in the same boat. When you press that button, Android Studio will sync the project and add the product library to the build.gradle file. As a result, library functions are available in Android Studio. It will add the Firebase Analytics library to my account, allowing me to log custom analytics events directly into Firebase Console.

As you can see, utilising the Firebase plugin in Android Studio makes it simple to integrate Firebase into Android.

What is the Role of Firebase in Android Development?

Whether you're creating a static app to show consumers the menu of a client restaurant or a completely new social media app, Firebase is the place to go.

Because you can't hardcode menu items and pricing in a menu-showing app, Firebase can surely help you out.

Because you don't want to start an Android studio project, alter the pricing, sign an APK, distribute to customers, and wait for them to upgrade the app.

That isn't a viable choice.

As a result, you'll need to use Firebase remote config, a Firebase offering that allows you to preserve menu items and their pricing as key-value pairs. And you can keep them up to date on the go.

Firebase isn't just for remote configuration; it also allows you to:
  • To authenticate users for your social networking apps, you can utilize Firebase Authentication.
  • Not only can you utilize Firebase Database to store user data such as chat messages, but you can also set security rules for the database. On top of that, Firebase offers two different database types.
    • a) Firebase Realtime Database: data is stored in JSON and synchronised in realtime via DataSnapshots to every connected client.
    • b) Firebase Cloud Firestore: where data is saved as documents and collections, allowing for even greater efficiency.
  • Firebase Cloud Messaging can be used to automate tasks such as delivering a notification at a specific event.
  • Finally, Cloud Storage can allow you save user-generated content such as their profile picture, multimedia messages, and so on.
