안드로이드 Invoke-customs are only supported starting with Android O (--min-api 26) 에러 발생 해결

문제발생

    implementation platform('com.google.firebase:firebase-bom:30.0.0')
    implementation 'com.google.firebase:firebase-analytics'

파이어베이스 애널리틱스 SDK를 추가하기 위해

Firebase Android BoM을 사용하여 모듈(앱 수준) Gradle 파일 build.gradle 에

애널리틱스 안드로이드 라이브러리의 종속 항목을 선언하니 

Invoke-customs are only supported starting with Android O (--min-api 26) 에러 발생

 

implementation 'com.google.firebase:firebase-analytics' 애널리틱스만 추가되면 발생하지 않지만

implementation platform('com.google.firebase:firebase-bom:30.0.0') Firebase Android BoM을 사용하면 발생

해결

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

모듈(앱 수준) Gradle 파일 build.gradle android 안에 위와 같이 추가해주면 해결
