See more HTML-to-XML/Text Examples

Demonstrates how to convert a string to the GSM character set. For more information about the GSM character set, see GSM Character Set

Note: This example requires Chilkat v9.5.0.79 or greater. Support for the GSM character set was added in v9.5.0.79.

// 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;

    // Demonstrates how to convert a string to the GSM character set byte representation.

    String s = "support@chilkatsoft.com, {abc}";

    // In the above string the a-z letters have the same 1-byte values in the GSM character set.
    // The '@' character is the 0x00 byte in GSM.
    // The curly brace chars are 2-bytes each in GSM -- each beginning with the 0x1B escape char.
    // The '.', ' ', and ',' are the same in GSM as us-ascii.

    // Let's convert to GSM.

    // bdGsm will contain the GSM bytes.
    CkBinData bdGsm = new CkBinData();

    // Append the string to bdGsm.  The 2nd arg "gsm" tells AppendString to
    // convert the incoming string to the gsm byte representation.
    success = bdGsm.AppendString(s,"gsm");

    // Let's examine what we have in hex:
    Log.i(TAG, bdGsm.getEncoded("hex"));

    // The result is:  737570706F7274006368696C6B6174736F66742E636F6D2C201B286162631B29

    // Save the GSM bytes to a file.
    success = bdGsm.WriteFile("qa_output/gsm.txt");

      // Note: If the incorrect library name is passed to System.loadLibrary,
