[Android] Failed to install the following Android SDK packages as some licences have not been accepted

안드로이드 라이센스 오류

안드로이드 스튜디오를 업데이트 한 후 아래와 같은 빌드 오류가 발생했다.

[Warning]
The specified Android SDK Build Tools version (30.0.1) is ignored, as it is below the minimum supported version (30.0.2) for Android Gradle Plugin 4.2.2.

Android SDK Build Tools 30.0.2 will be used.

To suppress this warning, remove "buildToolsVersion '30.0.1'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.

[Fail]
License for package Android SDK Build-Tools 30.0.2 not accepted.
