Facebook FB.ui send method not working on mobile web and need alternative - facebook

Question

I am trying to allow users of my app to notify multiple Facebook friends that they need them to vote for their favorite item on a web page. I have been using the FB send method (https://developers.facebook.com/docs/reference/dialogs/send/) and it has been working fine on desktop (code is below) but I just realized that I overlooked where it says in the docs that this dialog is "not supported on mobile devices."
Are there any alternatives to the send method that would allow a user to send a private message to their friends from mobile browsers? Perhaps a way to trick the api into thinking it's desktop?
I'm also open to using another FB dialog so long as it: 1) is functional from mobile browsers 2) allows pre-populating of recipients and 3) is private between the sender and the recipient such as a private message or notification.
Any ideas would be much appreciated. Thanks
Code for FB send method:
function resetSelector(){
$('#fs-user-list').empty();
$(".mutual-friends-link").fSelector({
max: 5,
excludeIds: exclusions,
facebookInvite: false,
lang: {
title: "Pick your mutual friends who will vote on the gifts (Last step)",
buttonSubmit: "Add Accomplices",
selectedLimitResult: "Limit is {5} people."
},
closeOnSubmit: true,
onSubmit: function(response){
var accompliceUid;
accomplices = response;
$('#index-accomplices').empty()
var i = 0
var FB_notification = function(accomplice, poll_id){
FB.api('https://graph.facebook.com/', 'post', {
id: "http://giftadvisor.herokuapp.com/polls/" + poll_id,
scrape: true
}, function(response){
FB.ui({
method: 'send',
to: [accomplice],
link: "http://giftadvisor.herokuapp.com/polls/" + poll_id,
}, fbCallback)
})
}
var fbCallback = function(){
console.log(i++)
if (i === accomplices.length){
window.location = "/polls/" + poll.id
}
}
_.each(accomplices, function(accomplice){
$('#index-accomplices').append('<img class="accomplices" src="http://graph.facebook.com/' + accomplice + '/picture?type=large">');
user = new User({uid: accomplice});
user.save(null,
{success: function(response){
console.log("users saved")
console.log(response.attributes.uid);
vote = new Vote();
vote.save({
user_id: response.attributes.id,
poll_id: poll.id,
image_url: "http://graph.facebook.com/" + response.attributes.uid + "/picture"
},{success: function(response){
FB_notification(accomplice, poll.id);
}
}
);
}});
});
// }});
},
onClose: function(){
// FB_notification(accomplices, poll.id);
}
});
}

The only thing I've seen approximating this is to use the now-deprecated Chat API. See, for example, what Grouper does.
Send dialog is really what I want, but failure on mobile web makes it useless. Have you found any other approaches that may work?
