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.
