+# Facebook for PhoneGap on Android #
+by Jos Shepherd
+
+This is an attempt to make a PhoneGap plugin from the Facebook Android SDK:
+https://github.com/facebook/facebook-android-sdk
+
+It is currently not functional (the login dialog is silently failing to appear)

+/**
+ * A sample implementation of asynchronous API requests.  This class provides
+ * the ability to execute API methods and have the call return immediately, 
+ * without blocking the calling thread.  This is necessary when accessing the 
+ * API in the UI thread, for instance.  The request response is returned to 
+ * the caller via a callback interface, which the developer must implement.
+ * 
+ * This sample implementation simply spawns a new thread for each request,
+ * and makes the API call immediately.  This may work in many applications,
+ * but more sophisticated users may re-implement this behavior using a thread
+ * pool, a network thread, a request queue, or other mechanism.  Advanced
+ * functionality could be built, such as rate-limiting of requests, as per
+ * a specific application's needs.
+ * 
+ * @see RequestListener
+ *        The callback interface.
