Ungzip Base64 String

See more Gzip Examples

Suppose you have a gzip in base64 representation that contains a text file, such as XML. This example shows how to decompress and access the string. 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.

    CkGzip gzip = new CkGzip();

    String gzipBase64 = "H4sIAAAAAAAE ... X6aZjXO3EwAA";

    CkBinData bd = new CkBinData();
    success = bd.AppendEncoded(gzipBase64,"base64");

    success = gzip.UncompressBd(bd);
    if (success != true) {
        Log.i(TAG, gzip.lastErrorText());
        return;
        }

    String strXml = bd.getString("utf-8");
    Log.i(TAG, "XML:");
    Log.i(TAG, strXml);

  }

  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."
