Setting up the new Firebase

At this year's Google I/O, Google announced a number of interesting new features in Firebase. The new Firebase is said to be a “Unified app platform for mobile developers” adding new tools to help develop faster, improve app quality, engage users and monetize apps.

For a quick intro to what the new Firebase is about, you can watch this video.

The new features that are included in this new Firebase include:

1. Crash Reporting
2. Cloud Messaging
3. Realtime database and storage
4. Analytics.
5. Notifications.
6. Dynamic Links.
7. App Indexing.
8. AdWords.
9. Firebase Invites etc

Registration

First point to get started with Firebase, is to create an account here if you don't have one already.

Setup

Prerequisites

Before you can begin to enjoy the new Firebase, please ensure your development machine satisfies these prerequisites:

• A device running Android 2.3 (Gingerbread) or newer, and Google Play services 9.0.1 or newer
• The Google Play services SDK from the Android SDK Manager
• Android Studio 1.5 or higher
• An Android Studio project and its package name

Add Firebase to your app

Next step is to add Firebase to your app on the Firebase console. Follow the following steps to add firebase to your app.

1. Create project

Navigate to the console. If you don't already have an existing Firebase project, click on "Create new project" and follow through the steps as shown in the gif below. Else, if you have an exisiting Google project, click on "Import Google Project"

2. Add Firebase to your app

Now that you've created the project, in the dashboard, click on "Add Firebase to your Android app".

To proceed, you need at least a package name unique to your app. If you plan on using Dynamic Links, Invites, and Google Sign-In support in Auth, you have to include a debug signing key SHA1 fingerprint.

To see your debug key SHA1 fingerprint, run the following command if you use Linux or Mac:

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android 

If you're running Windows, use this command:

keytool -list -v -keystore C:\Documents and Settings\[User Name]\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android 

The whole process is as shown below:

3. Configure your app

Clicking add app will download a google-services.json file. You should move this file to your projects app module directory. Usually <project>/app directory. Click continue and follow these instructions:

1. In your project-level build.gradle file, add the following lines (<project>/build.gradle):

buildscript {
  dependencies {
    // Add this line
    classpath 'com.google.gms:google-services:3.0.0'
  }
}

1. In your app-level build.gradle (<project>/<app-module>/build.gradle):

apply plugin: 'com.android.application'

android {
  // ...
}

dependencies {
  // ...
  implementation 'com.google.firebase:firebase-core:9.0.0'
}

// Add to the bottom of the file
apply plugin: 'com.google.gms.google-services'

Sync your gradle files with the project and you're ready to go with firebase.
