From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait(long timeoutMillis, int nanos) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. final void wait() Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public methods

build

Added in API level 35

public UsageEventsQuery build ()

Builds a read-only UsageEventsQuery object.

Returns
UsageEventsQuery	This value cannot be null.

setEventTypes

Added in API level 35

public UsageEventsQuery.Builder setEventTypes (int... eventTypes)

Sets the list of usage event types to be included in the query.

Note:

An empty array will be returned by UsageEventsQuery.getEventTypes() without calling this method, which indicates querying for all event types. Apps are encouraged to provide a list of event types. Only the matching types supplied will be used to query.

Parameters

eventTypes

int: the array of the usage event types. See UsageEvents.Event. This value cannot be null. Value is UsageEvents.Event.NONE, UsageEvents.Event.ACTIVITY_RESUMED, UsageEvents.Event.ACTIVITY_PAUSED, android.app.usage.UsageEvents.Event.END_OF_DAY, android.app.usage.UsageEvents.Event.CONTINUE_PREVIOUS_DAY, UsageEvents.Event.CONFIGURATION_CHANGE, android.app.usage.UsageEvents.Event.SYSTEM_INTERACTION, UsageEvents.Event.USER_INTERACTION, UsageEvents.Event.SHORTCUT_INVOCATION, android.app.usage.UsageEvents.Event.CHOOSER_ACTION, android.app.usage.UsageEvents.Event.NOTIFICATION_SEEN, UsageEvents.Event.STANDBY_BUCKET_CHANGED, android.app.usage.UsageEvents.Event.NOTIFICATION_INTERRUPTION, android.app.usage.UsageEvents.Event.SLICE_PINNED_PRIV, android.app.usage.UsageEvents.Event.SLICE_PINNED, UsageEvents.Event.SCREEN_INTERACTIVE, UsageEvents.Event.SCREEN_NON_INTERACTIVE, UsageEvents.Event.KEYGUARD_SHOWN, UsageEvents.Event.KEYGUARD_HIDDEN, UsageEvents.Event.FOREGROUND_SERVICE_START, UsageEvents.Event.FOREGROUND_SERVICE_STOP, android.app.usage.UsageEvents.Event.CONTINUING_FOREGROUND_SERVICE, android.app.usage.UsageEvents.Event.ROLLOVER_FOREGROUND_SERVICE, UsageEvents.Event.ACTIVITY_STOPPED, android.app.usage.UsageEvents.Event.ACTIVITY_DESTROYED, android.app.usage.UsageEvents.Event.FLUSH_TO_DISK, UsageEvents.Event.DEVICE_SHUTDOWN, UsageEvents.Event.DEVICE_STARTUP, android.app.usage.UsageEvents.Event.USER_UNLOCKED, android.app.usage.UsageEvents.Event.USER_STOPPED, android.app.usage.UsageEvents.Event.LOCUS_ID_SET, or android.app.usage.UsageEvents.Event.APP_COMPONENT_USED
