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