android.support.v4.content.FileProvider 클래스가 안드로이드 Kitkat에 없습니다.

Question

내 응용 프로그램에서 FileProvider을 사용하고 있습니다. 평소처럼 파일에 <Provider> 태그를 다음과 같이 선언했습니다.

<provider 
     android:name="android.support.v4.content.FileProvider" 
     android:authorities="com.jk.android.fileprovider" 
     android:exported="false" 
     android:grantUriPermissions="true"> 
     <meta-data 
      android:name="android.support.FILE_PROVIDER_PATHS" 
      android:resource="@xml/file_paths" /> 
</provider> 

나는 잘 작동 lollipop 버전이 안드로이드 장치에서 실행합니다. 내가 kitkat 버전을 시도 할 때 다음과 같은 오류를 보여줍니다 : 나는 this처럼 많은 솔루션을 시도했다하지만 나를 위해 작동하지 않습니다

FileProvider이 롤리팝 안드로이드 API 레벨 22에 도입 된, 그건 롤리팝 장치에서 테스트 할 때 ClassNotFoundException가 직면하지 않은 이유입니다. Android Kitkat에는 FileProvider 클래스가 없으므로 예외가 발생합니다. 파일 this post에 액세스하려는 경우
