The Amazon Fling SDK allows developers to enable second screen functionality within their apps. It is now possible to send media and web content from a mobile device to an Amazon Fire TV.
Functionality provided by the Amazon Fling SDK includes the ability to discover Fire TV devices from a controller app on a mobile device, control the playback of content sent from a controller app, and customize the user experience of a Fire TV player app. Fling controllers can be built into applications on Fire OS, Android, and iOS.
Developers can create a custom player application to receive content from the controller, or simply use the built-in media receiver included on Fire TV. More details on getting started with the Amazon Fling SDK can be found here:
