Activities that serve as the root of a task may give up certain task identifiers to activities above it in the task stack. These identifiers include the task base Intent, and the task name, color and icon used in the recent task list. The base @link{Intent} is used to match the task when relaunching based on an incoming Intent. *

To relinquish its identity the base activity must have the activity attribute android:relinquishTaskIdentity=”true” in the manifest.

Returns an new intent to start {@link NewDocumentActivity} as a new document in recents..


Activity that changes its task identifiers by setting a new {@link}

Creates a new {@link} with a new label and icon to change the appearance of this activity in the recents stack.
