How can I get the Facebook object id for a new web page?

I've got an Android app that integrates the Facebook Android SDK. We'd like to set it up so, at the users request, it dynamically creates a webpage and sends a "like" to Facebook for that page.

However, in order to do this it seems we need a Facebook Object ID for the webpage, and the page won't get a Facebook Object ID until someone physically loads the page and clicks the like button in the Javascript.

How can we开发者_开发知识库 get Facebook to assign an object ID for our page when it gets created?

You can get the webpage id by posting to the graph using ?id= url.
