<!-- Window layout affinity of this activity. Activities with the same window layout
affinity will share the same layout record. If an activity is launched in freeform window,
the activity will be launched to the latest position and size where any task, if the root
activity of that task shares the same window layout affinity with the activity being
launched. Window layout affinity is shared only among activities with the same UID.
affinity will share the same layout record. That is, if a user is opening an activity in
a new task on a display that can host freeform windows, and the user had opened a task
before and that task had a root activity who had the same window layout affinity, the
new task's window will be created in the same window mode and around the location which
the previously opened task was in.
<p>For example, if a user maximizes a task with root activity A and opens another
activity B that has the same window layout affinity as activity A has, activity B will
be created in fullscreen window mode. Similarly, if they move/resize a task with root
activity C and open another activity D that has the same window layout affinity as
activity C has, activity D will be in freeform window mode and as close to the position
of activity C as conditions permit. It doesn't require the user to keep the task with
activity A or activity C open. It won't, however, put any task into split-screen or PIP
window mode on launch.
<p>If the user is opening an activity with its window layout affinity for the first time,
the window mode and position is OEM defined.
<p>By default activity doesn't share any affinity with other activities. -->
