Set the Email Date Header to the Current System Date/Time

Demonstrates how to set the Date header field of an email to the computer's current date/time. Note: When an email object is instantiated, the Date header field is automatically added and initialized to the current system date/time. The need to explicitly set the Date header could arise when loading an email from a .eml. 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);

    boolean success = false;

    CkEmail email = new CkEmail();

    // At this point, a new email object has been instantiated, and it
    // already has a Date header field containing the current date/time.
    Log.i(TAG, "Date: " + email.emailDateStr());

    // We can also get the Date header like this:
    Log.i(TAG, "Date: " + email.getHeaderField("Date"));

    // Load a .eml into the email object:
    success = email.LoadEml("myEmlFiles/someEmail.eml");
    if (success != true) {
        Log.i(TAG, email.lastErrorText());
        return;
        }

    // Show the Date that was in the .eml
    Log.i(TAG, "Date: " + email.emailDateStr());

    // Now the Date header contains whatever was in the .eml
    // Let's update it to the current system date/time..

    CkDateTime dateTime = new CkDateTime();

    dateTime.SetFromCurrentSystemTime();

    success = email.SetDt(dateTime);
    if (success != true) {
        Log.i(TAG, email.lastErrorText());
        return;
        }

    // Now show that the Date is the current system time:
    Log.i(TAG, "Date: " + email.emailDateStr());
    Log.i(TAG, "Date: " + email.getHeaderField("Date"));

  }

  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."
