Quoted-Printable Encode/Decode a String

See more Encryption Examples

_LANGUAGE_ example to quoted-printable encode and decode a 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);

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

    CkCrypt2 crypt = new CkCrypt2();

    // Here's a string in Icelandic using non us-ascii chars:
    String s = "Ég get etið gler án þess að meiða mig.";

    crypt.put_CryptAlgorithm("none");
    crypt.put_EncodingMode("quoted-printable");

    // Quoted-printable encode/decode the iso-8859-1
    // representation of the string.  Notice how each
    // Icelandic char is represented by 1 byte:
    crypt.put_Charset("iso-8859-1");
    String qp = crypt.encryptStringENC(s);
    Log.i(TAG, "iso-8859-1:");
    Log.i(TAG, qp);
    String decoded = crypt.decryptStringENC(qp);
    Log.i(TAG, decoded);

    // Now do the same using utf-8. Notice how each
    // Icelandic char is represented by 2 bytes in utf-8:
    crypt.put_Charset("utf-8");
    String qp = crypt.encryptStringENC(s);
    Log.i(TAG, "utf-8:");
    Log.i(TAG, qp);
    String decoded = crypt.decryptStringENC(qp);
    Log.i(TAG, decoded);

  }

  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."
