Android Studio 프로젝트에 Lucene 추가

Question

Android Studio 2.1.2 프로젝트에 Lucene 6.2.0을 추가하는 데 문제가 있습니다. 그러나이 라이브러리를 IntelliJ IDEA에 추가하는 것은 문제가되지 않습니다. Lucene 파일을 내 libs 폴더에 복사 한 다음 here으로 표시된 jar 파일을 라이브러리로 추가하려고했습니다 (마우스 오른쪽 버튼 => 라이브러리로 추가). Build.gradle 잘보고 있었다 :

To run dex in process, the Gradle daemon needs a larger heap. 
 
It currently has approximately 910 MB. 
 
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB. 
 
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.

은 메이븐 중앙에서 종속성 이러한 라이브러리를 추가하는 시도하지만 결과는 상기와 동일했다.

compile fileTree(dir: 'libs', include: '*.jar') 

내 응용 프로그램이 오류없이 실행하지만 루씬 클래스가 인식되지 않은 :

Error:unsupported class file version 52.0 
Error:...while parsing org/apache/lucene/analysis/ar/ArabicAnalyzer.class 

나는이 방법을 시도했다.

내가 뭘 잘못하고있어?

Answer 1

문제는 지금 해결 된 것 같습니다.

Error:unsupported class file version 52.0 

라이브러리는 여전히 강력하게 충분한 같은 라이브러리를 사용하기 당신이 당신의 안드로이드 Studio 프로젝트 설정에서 1.8 이상 JDK를 선택한 경우에도 자바 8을 지원하지 않는 자바 8 (버전 52.0)와 안드로이드 API를 쓴 것을 의미한다. 틀 렸으면 고쳐줘.
