Transition from RandomizeKey to GenRandomBytesENC

Provides instructions for replacing deprecated RandomizeKey method calls with GenRandomBytesENC. Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

import android.widget.TextView;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {

    crypt.put_CipherMode("cbc");
    crypt.put_KeyLength(256);

    //  ------------------------------------------------------------------------
    //  The RandomizeKey method is deprecated:

    //  Generates and sets a random 32-byte (256-bit) secret key.
    crypt.RandomizeKey();

    //  ------------------------------------------------------------------------
    //  Do the equivalent using GenRandomBytesENC followed by SetEncodedKey

    crypt.SetEncodedKey(randomKeyBase64,"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."
