환경설정을 제대로 했는데 에러가 계속 납니다.
아래의 소스를 보시고 답변 부탁드립니다.

● 1) project : build.gradle

buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath ‘com.android.tools.build:gradle:3.1.0’

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files

    classpath 'com.google.gms:google-services:3.2.0'
}

}
allprojects {
repositories {
google()
jcenter()

    mavenCentral()
    maven { url 'http://devrepo.kakao.com:8088/nexus/content/groups/public/' }

위 에러 메시지는 제가 보기에 서포트 라이브러리의 버전이 맞지 않아서 발생하는 문제 같아요.

개발자님이 쓰시는 버전, firebase가 쓰는 버전, 카카오 SDK가 사용하는 버전이 다를 경우에 런타임 예외가 발생할 수 있는데요. 우선 카카오 SDK에서는 프래그먼트 등 제한적인 부분에서만 서포트 라이브러리를 사용하므로 문제가 되는 버전을 exclude 하는 방식으로 먼저 시도해 보시는게 맞을 것 같아요.

dependencies {
    api('com.android.support:recyclerview-v7:22.2.0') {
       exclude module: 'support-v4'
    }
 }

위와 같은 블로그 포스트 들에도 어떻게 conflict를 해결할 수 있는지 간단하게 나와있어요 :slight_smile:
