Sharing and the invocation framework

The BlackBerry platform lets you give users access to external services, such as Facebook, from a UI component or action item in your application. For example, users could tap

  • "Share" to share a photo with a Facebook friend
  • "Open in" to open an image in an image editor
  • "Set as" to set a ring tone
  • "Contact" to call a contact

You can give users access to external services in the action bar, action menu, or context menu.

Best practices

  • Order services alphabetically.
  • Include a Cancel button at the top left corner of the screen.
  • Avoid providing access to a group of services directly from the action bar. Allow users to access groups of services from the action menu instead.
