Prepend Added Header Fields to the Top

See more Email Object Examples

Demonstrates the Chilkat Email.PrependHeaders property. When true, header fields added through AddHeaderField or AddHeaderField2 are placed at the top of the header rather than appended at the bottom (the default is false). This affects only fields added after the property is set — it does not reorder fields that are already present. This example enables prepending and adds two custom header fields.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.

    super.onCreate(savedInstanceState);

    //  Demonstrates the Email.PrependHeaders property.  When true, header fields added via
    //  AddHeaderField (or AddHeaderField2) are prepended to the top of the header instead of
    //  appended to the bottom.  The default is false.
