[ERROR] An error occurred while running subprocess cordova.
cordova run android exited with exit code 1.
Re-running this command with the --verbose flag may provide more information.
이럴 때는
이렇게 넣어 주면 된다.
android.useAndroidX: 이 플래그가 로 설정되면 trueAndroid 플러그인은 지원 라이브러리 대신 적절한 AndroidX 라이브러리를 사용합니다. 플래그가 false지정되지 않은 경우 기본적으로 플래그가 사용됩니다.
android.enableJetifier: 이 플래그가 로 설정되면 trueAndroid 플러그인은 바이너리를 다시 작성하여 AndroidX 종속성을 사용하도록 기존 타사 라이브러리를 자동으로 마이그레이션합니다. 플래그가 false지정되지 않은 경우 기본적으로 플래그가 사용됩니다.
android.useAndroidX=true
android.enableJetifier=true
이럴 경우 support.v4 와 관련된 import를 사용할 수 없게 된다.
sdk 가 업데이트 된 이후에 사용할 수 없기 때문이다.
