I have done a procedure to zip a file. But I can't unzip the zip file by 7-zip.

    public static void zipFile(String zipFile, String srcFile) throws IOException {
    InputStream i = FileSystemStorage.getInstance().openInputStream(srcFile);
    OutputStream o = FileSystemStorage.getInstance().openOutputStream(zipFile);
    ZipOutputStream zos = new ZipOutputStream(o);
    zos.putNextEntry(new ZipEntry(srcFile));
    int len;
    byte[] buffer = new byte[1024];
    while ((len = i.read(buffer)) > 0) {
        zos.write(buffer, 0, len);
    }
    zos.closeEntry();
}

I didn't try this but I guess it would look pretty close to this:

try(ZipOutputStream output = new ZipOutputStream(destinationOutputStream)) {
  output.putNextEntry(new ZipEntry("NameOfFileInZip"));
  output.write(byteArrayContentOfFileInZip); 
}

Check out ZipOutputStream samples for further guidance. Should be pretty similar to standard JavaSE only with different packages and more limited API.
