Re-Encode (How to convert encodings)

See more Encryption Examples

Demonstrates how to convert a string from one encoding to another. 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 assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkCrypt2 crypt = new CkCrypt2();

    // Here are some bytes as a hex string
    String hex = "4142434445462140232425";

    // The ReEncode method converts a string from one encoding to another.
    // Valid encodings are "url", "base64", "qp", "hex", "modbase64", "base64url", "base32", "base58",
    // and any of the encodings listed here:  http://cknotes.com/chilkat-binary-encoding-list

    // Convert from hex to base64
    String b64 = crypt.reEncode(hex,"hex","base64");
    Log.i(TAG, "base64: " + b64);

    // Convert from base64 to base32
    String b32 = crypt.reEncode(b64,"base64","base32");
    Log.i(TAG, "base32: " + b32);

    // Convert from base32 back to hex
    hex = crypt.reEncode(b32,"base32","hex");
    Log.i(TAG, "hex: " + hex);

  }

  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."
