Firebase Backend in Android

Question

This is my project's gradle files, I'm trying to get it to sync. I have included error logs, and code . Below you will find the files in order.

I got most of my code from the firebase docs, and still keep getting a fail, when I try syncing my project

I think that you have to add the libraries of Firebase to your project, fo example if you need to use the storage you need to add the:

    compile 'com.google.firebase:firebase-storage:10.2.1'

in your gradle dependencies, but before of that you need to registrer your project in the Firebase page, get your key and downlowad the

google-services.json

for your project. Check the tutorials in their page.

In your application build.grade, try removing:

compile 'com.google.firebase:firebase-storage:11.2.0'
compile 'com.google.firebase:firebase-auth:11.2.0'
compile 'com.google.firebase:firebase-messaging:11.2.0'
compile 'com.google.firebase:firebase-database:11.2.0'

and replacing them with this dependency:

compile 'com.google.android.gms:play-services-gcm:8.4.0'
