Constants
COLOR_MODE_DEFAULT
public static final int COLOR_MODE_DEFAULT
Value for colorMode
indicating that the activity should use the
default color mode (sRGB, low dynamic range).
See also:
Constant Value: 0 (0x00000000)
COLOR_MODE_HDR
public static final int COLOR_MODE_HDR
Value of colorMode
indicating that the activity should use a
high dynamic range if the presentation display supports it.

CONFIG_RESOURCES_UNUSED
public static final int CONFIG_RESOURCES_UNUSED
This is probably not the constant you want, the resources compiler supports a less dangerous version of it, 'allKnown', that only suppresses all currently existing configuration change restarts depending on your target SDK rather than whatever the latest SDK supports, allowing the application to work with resources on future Platform versions.
Bit in configChanges
that indicates that the activity doesn't use Android
Resources at all and doesn't need to be restarted on any configuration changes. This bit
disables all restarts for configuration dimensions available in the current target SDK as
well as dimensions introduced in future SDKs. Use it only if the activity doesn't need
anything from its resources, and doesn't depend on any libraries that may provide resources
and need to respond to configuration changes. When set,
Activity.onConfigurationChanged(Configuration)
will be called instead of a restart,
and it\u2019s up to the implementation to ensure that no stale resource values remain loaded
anywhere in the code.
This overrides all other bits, and this is recommended to be used individually.
This is not a core resource configuration, but a higher-level value, so its constant starts at the high bits.
Constant Value: 134217728 (0x08000000)

public static final int CONFIG_SCREEN_LAYOUT
Bit in configChanges
that indicates that the activity

R.attr.configChanges
attribute. This will be
set by default for applications that target an earlier version
than Build.VERSION_CODES.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.
Constant Value: 1024 (0x00000400)
CONFIG_SMALLEST_SCREEN_SIZE
public static final int CONFIG_SMALLEST_SCREEN_SIZE
Bit in configChanges
that indicates that the activity
can itself handle the smallest screen size. Set from the
R.attr.configChanges
attribute. This will be
set by default for applications that target an earlier version
than Build.VERSION_CODES.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.

Bit in flags
corresponding to an immersive activity
that wishes not to be interrupted by notifications.
Applications that hide the system notification bar with
WindowManager.LayoutParams.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).
