Before we are able to use any of Firebase services, you need to connect the Firebase Cloud to your project. Let's begin!

## Step 2: Create a Firebase Project¶

• Click on the big Add Project Button, and enter a project name for your application (I will use PetApp)
• The next screen will ask if you want to enable Google Analytics for your app. This doesn't really matter since we won't be using it, but I would just disable it for now.
• Go ahead and click Create Project
• Wait for it to be done and click Continue. You have now created your first Firebase Project!

1. Click on the Android Icon to add Firebase to Android
2. The first field will ask you for your Android package name. To find it, go to the build.gradle(Module:app) file in your Android Studio project (It is found under Gradle Scripts). Look for the applicationId

3. Fill in a nickname for App nickname

4. We need the debug certificate finger. Open a terminal (look at your bottom bar), and key in the following command (choose based on your OS):

If you are facing issues with keytool, consider using the GUI method described here

# For Windows
keytool -list -v -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

# For Mac/Linux
keytool -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore

5. When prompted for the password, type in android

6. It will display the debug key under SHA1. Copy the numbers after it, and paste it into the signing certificate field on firebase.

7. Click Register

8. Download the google-services.json into your app folder. Then click Next

9. We now need to add Firebase SDK to our app. Go to the project-level build.gradle and add the following code under dependencies:

classpath 'com.google.gms:google-services:4.3.4'


10. Now go to the module-level build.gradle. Add the following code under plugins:

id 'com.google.gms.google-services'

11. While still in module-level build.gradle, add the following code under dependencies:

implementation platform('com.google.firebase:firebase-bom:26.2.0')

12. Press Sync Now near the top right.

13. Gradle will take some time to sync. You can see its progress near the bottom of the screen. Meanwhile you are done with the setup on the Firebase Website, so click Next and Continue to the Console.

We are now done with adding the core Firebase SDK! Now let us start adding the individual Firebase components!
