Workaround for the deprecated Crypt2.HashString method

Shows how to replace the deprecated HashString method. (Chilkat is moving away from the use of CkByteData.) 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);

    CkCrypt2 crypt = new CkCrypt2();

    crypt.put_Charset("utf-8");

    crypt.put_HashAlgorithm("sha256");

    String inputStr = "This is a test.";

    //  ------------------------------------------------------------------------
    //  The HashString method is deprecated:

    CkByteData outData = new CkByteData();

    success = crypt.HashString(inputStr,outData);

    //  ------------------------------------------------------------------------
    //  Workaround.
    //  (Chilkat is moving away from using CkByteData)

    crypt.put_EncodingMode("base64");
    String hash_base64 = crypt.hashStringENC(inputStr);

    Log.i(TAG, hash_base64);

  }

  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."
