My unzip funtion,it works but for index.html it gives above error

public static void unpackZip(String src, String dest, String folderName){

    final int BUFFER_SIZE = 4096;

    BufferedOutputStream bufferedOutputStream = null;
    FileInputStream fileInputStream;
    try {
        fileInputStream = new FileInputStream(src);
        ZipInputStream zipInputStream = new ZipInputStream(new BufferedInputStream(fileInputStream));
        ZipEntry zipEntry;

        while ((zipEntry = zipInputStream.getNextEntry()) != null){

            String zipEntryName = zipEntry.getName();

            String name = dest.substring(dest.lastIndexOf("/")-1);

            File FileName = new File(dest);
            if (!FileName.isDirectory()) {
                try {
                    if (FileName.mkdir()) {
                    } else {
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }

            File file = new File(dest+ "/" + folderName +"/" +zipEntryName);

            if (file.exists()){

            } else {
                if(zipEntry.isDirectory()){
                    file.mkdirs();
                }else{
                    byte buffer[] = new byte[BUFFER_SIZE];
                    FileOutputStream fileOutputStream = new FileOutputStream(file);
                    bufferedOutputStream = new BufferedOutputStream(fileOutputStream, BUFFER_SIZE);
                    int count;

                    while ((count = zipInputStream.read(buffer, 0, BUFFER_SIZE)) != -1) {
                        bufferedOutputStream.write(buffer, 0, count);
                    }

                    bufferedOutputStream.flush();
                    bufferedOutputStream.close();
                }
            }
        }
        zipInputStream.close();
    } catch (FileNotFoundException e) {

        e.printStackTrace();
    }catch (IOException e) {
        // TODO Auto-generated catch block

build.gradle

zip4j implementation 'com.github.joielechong:zip4jandroid:1.0.1'

allprojects {
    repositories {
        maven { url "https://jitpack.io" }

    }
}

Code

String source = destFilePath + "/" + fileNameList.get(i);
String target = destFilePath.getAbsolutePath();

    try {
           ZipFile zipFile = new ZipFile(source);
           zipFile.extractAll(target);
         } catch (ZipException e) {
           e.printStackTrace();
           }
