// 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 {
  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    TextView tv = new TextView(this);
    String outStr = "";

    CkXml xml = new CkXml();

    xml.LoadXml("<abc a=\"123\" b=\"apple\">Test</abc>");

    //  The UpdateAttribute and AddOrUpdateAttribute methods
    //  are identical.  Both will replace the attribute's value if it
    //  already exists, or insert a new attribute if it does not yet exist.

    //  Change the value of attribute "b" to "pear".
    xml.UpdateAttribute("b","pear");

    //  Because no attribute named "c" exists, UpdateAttribute
    //  will create it:
    xml.UpdateAttribute("c","orange");

    //  If an attribute's value is an integer, the AddToAttribute
    //  method may be called to update it by adding an integer value.
    //  For example, update the value of "a" to "130" by adding 7.
    xml.AddToAttribute("a",7);

    //  Examine the result:
    outStr += xml.getXml() + "\n";
    tv.setText(outStr);
    setContentView(tv);
  }

  static {
      // Important: Make sure the name passed to loadLibrary matches the shared library
      // found in your project's libs/armeabi directory.
      //  for "libchilkat.so", pass "chilkat" to loadLibrary
      //  for "libchilkatemail.so", pass "chilkatemail" to loadLibrary
      //  etc.
      // 
      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."
