Facebook Audience Network delivers smarter mobile monetization.
Its allows you to monetize your Android apps with Facebook ads.
The Audience Network gives publishers and developers the option to choose between three different ad units: banners, interstitials and native ads. All three ad units have access to the same great targeting and advertisers, since the ads are automatically rendered to fit the unit you chose. Whenever possible, a click on an ad doesn’t take your users out of your app. Instead, users can download other apps and visit webpages from within your app.
