+<p>
+            
+            This sample demonstrates how to use the Launcher Shortcuts API introduced in API 25.
+            This API allows an application to define a set of Intents which are displayed as
+            when a user long-presses on the app's launcher icon. Examples are given for
+            registering both links both statically in XML, as well as dynamically at runtime.
+            
+        </p>
