WARNING: The specified Android SDK Build Tools version (28.0.0) is ignored, as it is below the minimum supported version (28.0.2) for Android Gradle Plugin 3.2.0.

Android SDK Build Tools 28.0.2 will be used.

To suppress this warning, remove "buildToolsVersion '28.0.0'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.

볼드체로 된 부분을 참고.

 

이런 에러가 나면 google play licensing library가 잘 설정되어 있는지 확인해야 한다. 

 

지원하는 안드로이드 버전에 따라 rev 2 이전의 라이브러리가 필요하기도 하다. 

 

나도 이번에 1  버전이 설치가 되어 있지 않아 계속 위와 같은 에러가 발생. 

 

라이브러리 1을 재설치 후 정상 빌드가 되는 것을 확인했다.
