[android] solved Duplicate class android.support.v4.app.INotificationSideChannel found in modules core-1.9.0-runtime

 

오래된 외부 라이브러리를 사용 할때 

androidx.core 와 Duplicate 문제가 발생 할 때가 있다.

 

 

 

gradle.properties 파일에 옵션을 추가해주면 해결 될 때가 있다.

android.enableJetifier=true

 

• android.enableJetifier: 이 플래그가 true로 설정되면 Android 플러그인에서 자동으로 기존 타사 라이브러리를 이전하여 바이너리를 다시 작성해 AndroidX 종속 항목을 사용합니다. 지정하지 않으면 플래그는 기본적으로 false입니다.

 

원인은 구버전과 충돌이 발생하는데 enableJetifier 플래그를 사용하면 빌드시 최신 버전만 남기는 마이그래션을 지원하여 해결되는 것으로 보인다.
