// 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 requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    boolean success;

    // Create a text/plain part.
    CkMime ptMime = new CkMime();
    ptMime.SetBodyFromPlainText("This is the plain text body");
    Log.i(TAG, ptMime.getMime());
    Log.i(TAG, "****");

    // The ptMime contains:
    // ---------------------------------------
    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body
    // ---------------------------------------

    // Start with an empty MIME object...
    CkMime topLevelMime = new CkMime();

    // Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
    topLevelMime.NewMultipartMixed();

    // Append the ptMime as a child.
    topLevelMime.AppendPart(ptMime);
    Log.i(TAG, topLevelMime.getMime());
    Log.i(TAG, "****");

    // The topLevelMime contains:
    // --------------------------
    // 	Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
    // 
    // 	--------------010907090104040508040404
    // 	Content-Type: text/plain
    // 	Content-Transfer-Encoding: 7bit
    // 
    // 	This is the plain text body
    // 	--------------010907090104040508040404--
    // 

    // IMPORTANT: A copy of the MIME passed in AppendPart is appended.
    // Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
    // For example:
    ptMime.SetBody("this is the new plain text body.");
    // topLevelMime is unchanged.
    Log.i(TAG, topLevelMime.getMime());
    Log.i(TAG, "****");

    // To change the content in topLevelMime, we must get the text/plain part.
    // For example:
    CkMime ptMime2 = topLevelMime.GetPart(0);
    ptMime2.SetBody("this is the new plain text body.");

    // Now topLevelMime is changed.
    Log.i(TAG, topLevelMime.getMime());

      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."
