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)

Bit in configChanges that indicates that the activity can itself handle the 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.

Constant Value: 1024 (0x00000400)

CONFIG_SMALLEST_SCREEN_SIZE

Added in API level 13
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.

public static final int FLAG_IMMERSIVE

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). 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 Activity.setImmersive(boolean).
