Constants

ACTIVITY_PAUSED

Added in API level 29

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

Added in API level 29

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

Added in API level 29

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

Added in API level 21

public static final int CONFIGURATION_CHANGE

An event type denoting that the device configuration has changed.

Constant Value: 5 (0x00000005)

DEVICE_SHUTDOWN

Added in API level 29

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

Added in API level 29

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

Added in API level 29

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

Added in API level 29

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

Added in API level 28

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

Added in API level 28

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)

Constant Value: 15 (0x0000000f)

SCREEN_NON_INTERACTIVE

Added in API level 28

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).
