I was wondering if there is a way to open up the android clock application and start a timer using the activity starter. I want the user to be able to set there own timer with the android clock timer and then use that information to start a countdown inside an app inventor app. The user interface of the android timer is easier to use and more aesthetically appealing than one I think I can build out. Any help on specifically what Action, Class, and Packages are necessary would be greatly appreciated.
