The Sapling App supports many types of resources such as PDF’s, text documents, presentations, interactive labs, links, audio files and video files. Simply tap a resource icon in the All or Resources sections and the resource will display within the app.
You can also choose to open a resource in another application, such as Safari or Keynote. To do this, open the resource from the Resources section, tap the Share icon on the top right of the screen and select an eligible app to open the resource.
Currently the Android app does not support external resources. The only resources you can launch from within the Android app are Mobile Assignments.
