Constants

ACTIVITY_PAUSED

public static final int ACTIVITY_PAUSED

An event type denoting that an Activity moved to the background. This event has a package name and class name associated with it and can be retrieved using getPackageName() and getClassName(). If a package has multiple activities, this event is reported for each activity that moves to background. This event is corresponding to Activity.onPause() of the activity's lifecycle.

Constant Value: 2 (0x00000002)

ACTIVITY_RESUMED

public static final int ACTIVITY_RESUMED

An event type denoting that an Activity moved to the foreground. This event has a package name and class name associated with it and can be retrieved using getPackageName() and getClassName(). If a package has multiple activities, this event is reported for each activity that moves to foreground. This event is corresponding to Activity.onResume() of the activity's lifecycle.

Constant Value: 1 (0x00000001)

ACTIVITY_STOPPED

public static final int ACTIVITY_STOPPED

An activity becomes invisible on the UI, corresponding to Activity.onStop() of the activity's lifecycle.

Constant Value: 23 (0x00000017)

CONFIGURATION_CHANGE

public static final int CONFIGURATION_CHANGE

An event type denoting that the device configuration has changed.

Constant Value: 5 (0x00000005)

DEVICE_SHUTDOWN

public static final int DEVICE_SHUTDOWN

An event type denoting that the Android runtime underwent a shutdown process. A DEVICE_SHUTDOWN event should be treated as if all started activities and foreground services are now stopped and no explicit ACTIVITY_STOPPED and FOREGROUND_SERVICE_STOP events will be generated for them.

The DEVICE_SHUTDOWN timestamp is actually the last time UsageStats database is persisted before the actual shutdown. Events (if there are any) between this timestamp and the actual shutdown is not persisted in the database. So any open events without matching close events between DEVICE_SHUTDOWN and DEVICE_STARTUP should be ignored because the closing time is unknown.

Constant Value: 26 (0x0000001a)

DEVICE_STARTUP

public static final int DEVICE_STARTUP

An event type denoting that the Android runtime started up. This could be after a shutdown or a runtime restart. Any open events without matching close events between DEVICE_SHUTDOWN and DEVICE_STARTUP should be ignored because the closing time is unknown.

Constant Value: 27 (0x0000001b)

FOREGROUND_SERVICE_START

public static final int FOREGROUND_SERVICE_START

An event type denoting start of a foreground service. This event has a package name and class name associated with it and can be retrieved using getPackageName() and getClassName(). If a package has multiple foreground services, this event is reported for each service that is started.

Constant Value: 19 (0x00000013)

FOREGROUND_SERVICE_STOP

public static final int FOREGROUND_SERVICE_STOP

An event type denoting stop of a foreground service. This event has a package name and class name associated with it and can be retrieved using getPackageName() and getClassName(). If a package has multiple foreground services, this event is reported for each service that is stopped.

Constant Value: 20 (0x00000014)

KEYGUARD_HIDDEN

public static final int KEYGUARD_HIDDEN

An event type denoting that the screen's keyguard has been hidden. This typically happens when the user unlocks their phone after turning it on.

Constant Value: 18 (0x00000012)

KEYGUARD_SHOWN

public static final int KEYGUARD_SHOWN

An event type denoting that the screen's keyguard has been shown, whether or not the screen is off.

Constant Value: 17 (0x00000011)

MOVE_TO_BACKGROUND

public static final int MOVE_TO_BACKGROUND

This constant is deprecated.
by ACTIVITY_PAUSED

Constant Value: 2 (0x00000002)

MOVE_TO_FOREGROUND

public static final int MOVE_TO_FOREGROUND

This constant is deprecated.
by ACTIVITY_RESUMED

Constant Value: 1 (0x00000001)

NONE

public static final int NONE

No event type.

Constant Value: 0 (0x00000000)

SCREEN_INTERACTIVE

public static final int SCREEN_INTERACTIVE

An event type denoting that the screen has gone in to an interactive state (turned on for full user interaction, not ambient display or other non-interactive state).

Constant Value: 15 (0x0000000f)

SCREEN_NON_INTERACTIVE

public static final int SCREEN_NON_INTERACTIVE

An event type denoting that the screen has gone in to a non-interactive state (completely turned off or turned on only in a non-interactive state like ambient display).

Constant Value: 16 (0x00000010)

SHORTCUT_INVOCATION

public static final int SHORTCUT_INVOCATION

An event type denoting that an action equivalent to a ShortcutInfo is taken by the user.

See also:

ShortcutManager.reportShortcutUsed(String)

Constant Value: 8 (0x00000008)

STANDBY_BUCKET_CHANGED

public static final int STANDBY_BUCKET_CHANGED

An event type denoting a change in App Standby Bucket. The new bucket can be retrieved by calling getAppStandbyBucket().

See also:

UsageStatsManager.getAppStandbyBucket()

Constant Value: 11 (0x0000000b)

USER_INTERACTION

public static final int USER_INTERACTION

An event type denoting that a package was interacted with in some way by the user.

Constant Value: 7 (0x00000007)
