title: Zipping files and folders in android
body: <p>So I created a class follwoing the examples found here. <a href="http://www.jondev.net/articles/Zipping_Files_with_Android_%28Programmatically%29" rel="nofollow noreferrer">http://www.jondev.net/articles/Zipping_Files_with_Android_%28Programmatically%29</a> which is great, it works wonders, for files. When it comes to folders it does not work. I tried switching the strings to files and using isDirectory, but it was a no go. Here is the code:</p>
  
  <pre><code>import android.util.Log; 
  import java.io.BufferedInputStream;
  import java.io.BufferedOutputStream;
  import java.io.FileInputStream;
  import java.io.FileOutputStream;
  import java.util.zip.ZipEntry;
  import java.util.zip.ZipOutputStream;
  
  public class Compress {
  
      private static final int BUFFER = 2048;
      private String[] _files;
      private String _zipFile;
  
      public Compress(String[] files, String zipFile) {
          _files = files;
          _zipFile = zipFile;
      }
  
      public void zip() {
          try {
              BufferedInputStream origin = null;
              FileOutputStream dest = new FileOutputStream(_zipFile);
              ZipOutputStream out = new ZipOutputStream(new BufferedOutputStream(
                      dest));
              byte data[] = new byte[BUFFER];
              for (int i = 0; i &lt; _files.length; i++) {
                  Log.v("Compress", "Adding: " + _files[i]);
                  FileInputStream fi = new FileInputStream(_files[i]);
                  origin = new BufferedInputStream(fi, BUFFER);
                  ZipEntry entry = new ZipEntry(_files[i].substring(_files[i]
                          .lastIndexOf("/") + 1));
                  out.putNextEntry(entry);
                  int count;
                  while ((count = origin.read(data, 0, BUFFER)) != -1) {
                      out.write(data, 0, count);
                  }
                  origin.close();
              }
              out.close();
          } catch (Exception e) {
              e.printStackTrace();
          }
      }
  }
  </code></pre>
