8 Introduction
9 ------------
10
11 This sample shows the basic usage of the new Document-Centric Apps API. The new
12 API modifies the meaning of the Intent#FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET flag, which is
13 now deprecated. In versions before L it serves to define a boundary between the main task and a
14 subtask. The subtask holds a different thumbnail and all activities in it are finished when the
15 task is reset. In L this flag causes a full break with the task that launched it. As such it has
16 been renamed to Intent#FLAG_ACTIVITY_NEW_DOCUMENT.
17
18 This sample mainly uses Intent flags in code. But Activities can also specify in their manifests
19 that they shall always be launched into a new task in the above manner using the new activity
20 attribute documentLaunchMode which may take on one of three values, intoExisting equivalent to
21 NEW_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.
