와 같은 오류가 뜨면서 뜨지 않았다.

 

이유를 찾아보니...

 

Proguard 설정을 해주어야 한다고 한다.

 

 

위와 같이

 

Project Settings - Player - Publishing Settings - Build - Custom Proguard File를 체크해주자

 

 

그럼 다음과 같은 파일이 하나 생기는데

 

 

-keep class com.google.android.gms.games.leaderboard.** { *; }
-keep class com.google.android.gms.games.snapshot.** { *; }
-keep class com.google.android.gms.games.achievement.** { *; }

-keep class com.google.android.gms.games.quest.** { *; }
-keep class com.google.android.gms.nearby.** { *; }

 

다음과 같이 작성하고 저장한다.

 

 

Assets - External Depandency Manager - Android Resolver - Force Resolve를 해주면 완료.

 

(만약 현재 Platform이 Android가 아니라면 Android로 Switch 해준다)

 

 

 

성공적으로 사용자 인터페이스가 뜨는 모습
