8Introduction
9------------
10
11This sample shows the basic usage of the new Document-Centric Apps API. The new
12API modifies the meaning of the Intent#FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET flag, which is
13now deprecated. In versions before L it serves to define a boundary between the main task and a
14subtask. The subtask holds a different thumbnail and all activities in it are finished when the
15task is reset. In L this flag causes a full break with the task that launched it. As such it has
16been renamed to Intent#FLAG_ACTIVITY_NEW_DOCUMENT.
17
18This sample mainly uses Intent flags in code. But Activities can also specify in their manifests
19that they shall always be launched into a new task in the above manner using the new activity
20attribute documentLaunchMode which may take on one of three values, “intoExisting” equivalent to
21NEW_DOCUMENT, “always” equivalent to NEW_DOCUMENT | MULTIPLE_TASK, “none” the default, and
22“never” which will negate the effect of any attempt to launch the activity with NEW_DOCUMENT.
