A notification with no importance: shows nowhere, is blocked.

const val IMPORTANCE_UNSPECIFIED = -1000: Int

Value signifying that the user has not expressed an importance. This value is for persisting preferences, and should never be associated with an actual notification.

const val INTERRUPTION_FILTER_ALARMS = 4: Int

Interruption filter constant - Alarms only interruption filter - all notifications except those of category CATEGORY_ALARM are suppressed. Some audio streams are muted.

const val INTERRUPTION_FILTER_ALL = 1: Int

See priorityCallSenders, priorityCategories, priorityMessageSenders to define or query this criteria. Users can additionally specify packages that can bypass this interruption filter.

const val INTERRUPTION_FILTER_UNKNOWN = 0: Int

Interruption filter constant - returned when the value is unavailable for any reason.

fun areNotificationsEnabled(): Boolean

Returns whether notifications from the calling package are not blocked.

fun canUseFullScreenIntent(): Boolean

Returns whether the calling app can send fullscreen intents.

Fullscreen intents were introduced in Android HONEYCOMB, where apps could always attach a full screen intent to their notification via setFullScreenIntent}.

Android Q introduced the USE_FULL_SCREEN_INTENT permission, where SystemUI will only show the full screen intent attached to a notification if the permission is declared in the manifest.

Starting from Android UPSIDE_DOWN_CAKE, apps may not have permission to use USE_FULL_SCREEN_INTENT. If the FSI permission is denied, SystemUI will show the notification as an expanded heads up notification on lockscreen.

To request access, add the USE_FULL_SCREEN_INTENT permission to your manifest, and use ACTION_MANAGE_APP_USE_FULL_SCREEN_INTENT to send the user to the settings page where they can grant your app the FSI permission.
