Firebase compatibility errors

I have a problem that I always had, and tried to understand it, but never succesfully. The compatibility between firebase implementations. I take the repositories from https://mvnrepository.com/artifact/com.google.firebase , but it doesn't help me. I event put apply plugin: 'com.google.gms.google-services' at the end of build.gradle, such in dependecies.
My implementations are:
implementation 'com.google.firebase:firebase-core:16.0.8'
implementation 'com.google.firebase:firebase-auth:16.2.0'
implementation 'com.google.firebase:firebase-firestore:18.1.0'
implementation 'com.google.firebase:firebase-storage:16.1.0'
It works very well without last one (storage) but I needed that, and when I put it there, i get some errors. If someone can explain why it works well with some versions, and with some not, I would apreciate that.
The error i get is:
java.lang.NoClassDefFoundError: Failed resolution of: Lcom/google/firebase/FirebaseApp$IdTokenListenersCountChangedListener;

when I have updated Gradle this nothing-saying error changed to proper one - the issue was that Google database Room dependency hadn't had proper cerificate and I needed to change openjdk9 to openjdk8 (I am using Ubuntu), then error disappeared

Duplicate class MultiDex$V14.class

My Android gradle build is failing during the ProGuard phase with a duplicate class error for MultiDex$V14.class (see below). I understand what a duplicate class is and I know what MultiDex is but I still don't understand how it's a duplicate.
Questions:
I see one definition is in multidex.jar, of course. How can I tell where the other is defined?
Isn't ProGuard supposed to remove duplicate entries instead of complaining about them?
The "What went wrong" description at the bottom seems unrelated to the duplicate class. Is it?

Error Building Android App

I am getting a weird error when I am trying to build a app. I don't think it's related to my code and need some help in resolving it. When I press run, the logcat giving me this error:

I am wondering if it to do with my phone's hardware or the cyanogenmod software running on it which causes the error.
Thank you for the help.

You hit the DEX 64k method limit.
There are few solutions which will help you to resolve this problem:
remove unused gradle dependencies
replace libaries with huge amount of methods with smaller ones, e.g.:
compile 'com.google.android.gms:play-services-analytics:8.4.0'
->
compile 'com.google.android.gms:play-services-base:8.4.0'
compile 'com.google.android.gms:play-services-location:8.4.0'
compile 'com.google.android.gms:play-services-maps:8.4.0'
...
remove unused code by configuring the ProGuard
enable Multidex:
build.gradle
android {
...
defaultConfig {
...
// Enabling multidex support.
multiDexEnabled true
}
...
}
dependencies {
compile 'com.android.support:multidex:1.0.0'
}
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.android.multidex.myapplication">
<application
...
android:name="android.support.multidex.MultiDexApplication">

</manifest>
Reference:
Building Apps with Over 65K Methods.

This line com.android.dex.DexIndexOverflowException: method ID not in [0, 0xffff]: 65536 states that you are over the 64k method limit the Compiler has for every .dex file. Read up on it. Solutions include using Multidex or more solutions here https://www.contentful.com/blog/2014/10/30/android-and-the-dex-64k-methods-limit/. This maybe a duplicate of other issues. Look at
How to solve the issue with Dalvik compiler limitation on 64K methods?
