```
String url  ="https://m.facebook.com/messages/read/?fbid=101631428274763";
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);

```

I want to directly send some messages. This way I am able to send message to fb page...but, not able to add some texts to text field. So, how can I send messages? I know that I can do that by `intent.putExtra` but, what the `name` would be?
