+Android Studio Support
+-----------------------
+
+You can also build and run SampleApp (and some other experimental apps) using Android
+Studio.  To create the project either select "import project" from the quickstart
+screen or use File -> Open.  In both cases you'll need to select ./platform_tools/android/apps
+as the root directory of your project.
+
+Finally to be able to build within Android studio it needs to know the path to 
+ninja so you will need to add a properties file and populate it with the path
+to depot_tools.  The syntax and location of that file is...
+ 
+    # 
+    # file location: ./platform_tools/android/apps/gradle.properties
+    #
+    depot_tools.dir=<path_to_depot_tools>
+    
+That should be all the setup you need.  You should now be able to build and deploy
+SampleApp on ARM, Intel, and MIPS devices.
