Sharing and the Invocation Framework
The BlackBerry Application Platform lets you give users access to external services, such as Facebook, from a UI component or action item in your app. For example, users can 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.
Order the external services alphabetically.
Include a Cancel button in the top-left corner of the screen.
Avoid providing access to external services directly from the action bar. Allow users to access groups of services from the action menu instead.
