Firebase Admin SDK causes gradle "Dependency Error"

Question

I'm trying to add the Firebase Admin SDK to my project. When I add this:

compile 'com.google.firebase:firebase-admin:4.1.1'

It gives me a "Dependency Error" When I sync.

The stacktrace:

You can't use the Firebase Admin SDK inside an Android app. You have to write a different Java program for that, which normally resides on a server you control.

See also this question for other problems that can come up if you try to use firebase-admin from within an Android app.

I have an Android project. And I'm not willing to buy a server for this reason. All I want is custom authentication. It's a pitty Google makes it this complicated. – Ali Bdeir Feb 10 '17 at 16:05
why don't you just use custom auth of Firebase API? This tutorial explained how to add custom auth to your apps https://forum.xda-developers.com/showpost.php?p=66902019&postcount=5 also you can check firebase doc itself – Elias Fazel Feb 10 '17 at 16:13
All these are trying to make me use the admin sdk – Ali Bdeir Feb 10 '17 at 16:14
I don't want neither email nor password. I just want phone number. Sort of like whatsapp – Ali Bdeir Feb 10 '17 at 16:14
i recommend this Fabric guide https://docs.fabric.io/android/digits/sign-in-with-phone-number.html good luck – Elias Fazel Feb 10 '17 at 16:20
