ActionScript extensions

The Extensions feature in Flash Lite 3.1 allows third-party developers to add features and ActionScript APIs to Flash Lite using a static or dynamically linked library. The DLL provides the implementation for the features, and Flash Lite allows the DLL to be used by calling ActionScript APIs. This makes it possible for Flash Lite developers to interact with APIs exposed by host devices by writing a DLL that bridges the capabilities of the device and of the Flash Player. These extensions can be statically or dynamically linked to the host implementation. For example, using this capability, developers can write applications that access the device’s filing system, or use GPS data provided by the device, and so on.
