Android: compress files in zip

Very good solution how to create zip archive by Java code on Android Zipping Files with Android (Programmatically).

I created a separate Class file Compress.java

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 < _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(); 
    } 
 
  } 
 
} 

To use this class in you Activity, do the following code:

File dir = new File(Environment.getExternalStorageDirectory(), 
				"mydir");
String zipName = dir.toString()+"zipname.zip";

String[] files = new String[] {dir.toString()+"file_one.jpg", dir.toString()+"file_two.gif"};

Compress c = new Compress(files, zipName);
c.zip();
