How to create a .zip archive excluding (skipping) files that match a set of wildcarded patterns. 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 requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkZip zip = new CkZip();

    success = zip.NewZip("test.zip");
    if (success != true) {
        Log.i(TAG, zip.lastErrorText());
        return;
        }

    // Create a string array object with our set of filename patterns
    // to be excluded:
    CkStringArray sa = new CkStringArray();
    success = sa.Append("*.bak");
    success = sa.Append("*.tmp");

    // Tell the zip object to use these exclusions:
    zip.SetExclusions(sa);

    // Append a directory tree.  The AppendFiles does
    // not read the file contents or append them to the zip
    // object in memory.  It simply appends references
    // to the files so that when WriteZip (or WriteZipAndClose,
    // or WriteExe, etc.) is called, the files are compressed
    // and encrypted.
    boolean recurse = true;
    success = zip.AppendFiles("/temp/a/*",recurse);

    success = zip.WriteZipAndClose();
    if (success != true) {
        Log.i(TAG, zip.lastErrorText());
        return;
        }

    Log.i(TAG, "Zip Created!");

      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."
