Get the POP3 UIDL of an Email

See more Email Object Examples

Demonstrates the read-only Chilkat Email.Uidl property, which contains the unique message identifier assigned by a POP3 server; the value is also represented by the X-UIDL header field. This example sets X-UIDL directly to illustrate how it maps to the Uidl property (normally the value comes from the POP3 server during download).

// 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);

    //  Demonstrates the read-only Email.Uidl property, which contains the unique message
    //  identifier assigned by a POP3 server.  The value is represented by the X-UIDL header
    //  field.  Here we set X-UIDL directly to show how it maps to the Uidl property.

    CkEmail email = new CkEmail();

    //  Normally the POP3 server assigns this; we set it here for demonstration.
    email.AddHeaderField("X-UIDL","0000000123abcdef");

    Log.i(TAG, "Uidl = " + email.uidl());

  }

  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."
