Bit in configChanges
that indicates that the activity
can itself handle density changes. Set from the
configChanges
attribute.
Bit in configChanges
that indicates that the activity
can itself handle changes to the font scaling factor. Set from the
configChanges
attribute. This is
not a core resource configuration, but a higher-level value, so its
constant starts at the high bits.
Bit in configChanges
that indicates that the activity
can itself handle changes to the keyboard type. Set from the
configChanges
attribute.
Bit in configChanges
that indicates that the activity
can itself handle changes to the keyboard or navigation being hidden/exposed.
Note that inspite of the name, this applies to the changes to any
hidden states: keyboard or navigation.
Set from the configChanges
attribute.
Bit in configChanges
that indicates that the activity
can itself handle the change to layout direction. Set from the
configChanges
attribute.
Bit in configChanges
that indicates that the activity
can itself handle changes to the locale. Set from the
configChanges

that indicates that the activity
can itself handle changes to the IMSI MCC. Set from the
configChanges

Bit in configChanges
that indicates that the activity
can itself handle changes to the IMSI MNC. Set from the

Bit in configChanges
that indicates that the activity
can itself handle changes to the screen layout. Set from the

Bit in configChanges
that indicates that the activity
can itself handle the screen size. Set from the
configChanges
attribute. This will be
set by default for applications that target an earlier version
than HONEYCOMB_MR2
...
however, you will not see the bit set here becomes some
applications incorrectly compare configChanges
against
an absolute value rather than correctly masking out the bits
they are interested in. Please don't do that, thanks.

indicating that tasks started with this activity are to be
removed from the recent list of tasks when the last activity in the task is finished.
autoRemoveFromRecents
Bit in flags
indicating that, when the activity is the root
of a task, that task's stack should be cleared each time the user
re-launches it from home. As a result, the user will always
return to the original activity at the top of the task.
This flag only applies to activities that
are used to start the root of a new task. Set from the
clearTaskOnLaunch
attribute.

Bit in flags
corresponding to an immersive activity
that wishes not to be interrupted by notifications.
Applications that hide the system notification bar with
FLAG_FULLSCREEN
may still be interrupted by high-priority notifications; for example, an
incoming phone call may use
fullScreenIntent
to present a full-screen in-call activity to the user, pausing the
current activity as a side-effect. An activity with
FLAG_IMMERSIVE
set, however, will not be interrupted; the
notification may be shown in some other way (such as a small floating
"toast" window).
Note that this flag will always reflect the Activity's
android:immersive
manifest definition, even if the Activity's
immersive state is changed at runtime via
setImmersive(boolean)
.
Bit in flags
indicating whether this activity is able to
run in multiple processes. If
true, the system may instantiate it in the some process as the
process starting it in order to conserve resources. If false, the
default, it always runs in processName
. Set from the
multiprocess
attribute.
Bit in flags
indicating that this activity is to be persisted across
reboots for display in the Recents list.
persistable
Bit in flags
: If set, a single instance of the receiver will
run for all users on the device. Set from the
singleUser
attribute. Note that this flag is
only relevant for ActivityInfo structures that are describing receiver
components; it is not applied to activities.

indicating that the activity's state
is not required to be saved, so that if there is a failure the
activity will not be removed from the activity stack. Set from the
stateNotNeeded
attribute.
