Create Compressed .tgz (.tar.gz) TAR Archive

See more Tar Archive Examples

Demonstrates how to create a compressed TAR archive containing an entire directory tree. This example creates a compressed archive using GZip compression. The typical file extension used is .tgz or .tar.gz. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    boolean success = false;

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkTar tar = new CkTar();

    // The TAR component will produce a  GNU tar 1.13.x format
    // archive by default.
    // It is also possible to create PAX -- POSIX 1003.1-2001 format
    // or USTAR -- POSIX 1003.1-1988 format.
    // Set the WriteFormat property to "gnu", "pax", or "ustar" to
    // choose the output TAR format:
    tar.put_WriteFormat("gnu");

    // Add a directory tree to be included in the output TAR archive:
    success = tar.AddDirRoot("/Users/chilkat/temp/abc123");
    if (success != true) {
        Log.i(TAG, tar.lastErrorText());
        return;
        }

    // Create the compressed TAR archive.
    // Note: You may use UNC paths, absolute, or relative paths.
    success = tar.WriteTarGz("/Users/chilkat/testData/tar/abc123.tgz");
    if (success != true) {
        Log.i(TAG, tar.lastErrorText());
        return;
        }

    Log.i(TAG, "Success.");

  }

  static {
      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
