Android DocumentCentricRecents Sample
|
||
|
|
===================================
|
||
|
|
|
||
|
|
Sample demonstrating the basic usage of the new 'Document Centric Apps' API.
|
||
|
|
It let's you create new documents in the system overview menu and persists its
|
||
|
|
state through reboots.
|
||
|
|
|
||
|
|
Introduction
|
||
|
|
------------
|
||
|
|
|
||
|
|
This sample shows the basic usage of the new Document-Centric Apps API. The new
|
||
|
|
API modifies the meaning of the Intent#FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET flag, which is
|
||
|
|
now deprecated. In versions before L it serves to define a boundary between the main task and a
|
||
|
|
subtask. The subtask holds a different thumbnail and all activities in it are finished when the
|
||
|
|
task is reset. In L this flag causes a full break with the task that launched it. As such it has
|
||
|
|
been renamed to Intent#FLAG_ACTIVITY_NEW_DOCUMENT.
|
||
|
|
|
||
|
|
This sample mainly uses Intent flags in code. But Activities can also specify in their manifests
|
||
|
|
that they shall always be launched into a new task in the above manner using the new activity
|
||
|
|
attribute documentLaunchMode which may take on one of three values, “intoExisting” equivalent to
|
||
|
|
NEW_DOCUMENT, “always” equivalent to NEW_DOCUMENT | MULTIPLE_TASK, “none” the default, and
|
||
|
|
“never” which will negate the effect of any attempt to launch the activity with NEW_DOCUMENT.
|
||
|
|
|
||
|
|
