Can I customize the email composition experience with MvvmCross

Overview of MvvmCross Email Plugin

The MvvmCross Email plugin is supported on all platforms, including Windows UWP and WPF, although the implementation on these platforms is simplistic, relying on `mailto:` URL requests to open the default email client[1]. For more advanced customization, you might need to extend or replace this functionality with platform-specific code.

Basic Email Composition

To compose an email using MvvmCross, you typically resolve the `IMvxComposeEmailTask` interface and call its `ComposeEmail` method. This method takes parameters such as the recipient's email address, CC, subject, body, and whether the body is HTML. Here's an example:

csharp
var emailTask = Mvx.IoCProvider.Resolve();
emailTask.ComposeEmail("
 <script language='JavaScript' type='text/javascript'>
 <!--
 var prefix = 'm&#97;&#105;lt&#111;:';
 var suffix = '';
 var attribs = '';
 var path = 'hr' + 'ef' + '=';
 var addy13004 = 'r&#101;c&#105;p&#105;&#101;nt' + '&#64;';
 addy13004 = addy13004 + '&#101;x&#97;mpl&#101;' + '&#46;' + 'c&#111;m';
 document.write( '<a ' + path + '\'' + prefix + addy13004 + suffix + '\'' + attribs + '>' );
 document.write( addy13004 );
 document.write( '<\/a>' );
 //-->
 </script><script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '<span style=\'display: none;\'>' );
 //-->
 </script>This e-mail address is being protected from spambots. You need JavaScript enabled to view it
 <script language='JavaScript' type='text/javascript'>
 <!--
 document.write( '</' );
 document.write( 'span>' );
 //-->
 </script>", string.Empty, "MvvmCross Email", "I (Resource.Id.recipientEditText);
        var subjectEditText = FindViewById(Resource.Id.subjectEditText);
        var bodyEditText = FindViewById(Resource.Id.bodyEditText);

        // Button click handler to send the email
        var sendButton = FindViewById(Resource.Id.sendButton);
        sendButton.Click += async (sender, args) =>
        {
            // Implement logic to send the email using a custom method or library
            await SendEmailAsync(recipientEditText.Text, subjectEditText.Text, bodyEditText.Text);
        };
    }

    private async Task SendEmailAsync(string recipient, string subject, string body)
    {
        // Implement email sending logic here, possibly using a third-party library
        // or native Android Intent to open the email client with pre-filled fields
    }
}

Conclusion

While MvvmCross provides a basic email composition capability, achieving a highly customized email composition experience requires implementing platform-specific code or integrating third-party libraries. This approach allows you to leverage the strengths of each platform while maintaining a cross-platform architecture with MvvmCross.
