빌드시 난독화를 true로 설정하였더니 발생되었다. 물론 false 처리하면 정상적으로 빌드가 되었다.
문제는 정확한 클랙스나 패키지에 대한 정보 없는 오류 내용을 보여주고 있다는 데에 있다.
좀 더 정확한 정보를 주면 오류처리가 좀 더 수월할텐데… 때때로 아쉬울 때가 많다.

문제가 발생한 클래스를 찾아서 proguard-rules.pro 파일에 dontwarn 처리를 하든 keep를 하던 하면 되는데 찾기가 쉽지않다. 좀 더 상세하게 알려주면 좋으련만…
[예시]
-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
Android Gralde Plugin : 14 warnings 내용을 확인하였고, 혹시나 하는 마음에 처리하였다.
-dontwarn androidx.appcompat.widget.DrawableUtils.** –실패!!!
[해결]
-dontwarn androidx.appcompat.widget.**
빌드시간이 상당히 길어졌다.
디버깅거나 테스트를 빨리 하기 위해서는 난독화 설정을 false로 하고 빌드하게되면 시간을 벌 수 있다.
빌드는 성공하였지만 혹시라도 오류가 발생되고 앱을 중지되었다면 다른 라이브러리의 문제이다.
만약 오류원인을 찾을 수 없을 때 난독화 설정을 false로 처리 후 앱이 정상적으로 동작한다면 난독화가 원인인 경우가 있으니 참고하자.
