Kotlin |Java

public final class UsageEventsQuery
extends Object implements Parcelable

java.lang.Object
↳	android.app.usage.UsageEventsQuery

---

An Object-Oriented representation for a UsageEvents query. Used by UsageStatsManager#queryEvents(UsageEventsQuery) call.

Summary

Nested classes
class	UsageEventsQuery.Builder Builder for UsageEventsQuery.

Inherited constants

From interface android.os.Parcelable int CONTENTS_FILE_DESCRIPTOR Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor. int PARCELABLE_WRITE_RETURN_VALUE Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)".

Fields
public static final Creator<UsageEventsQuery>	CREATOR

Public methods
int	describeContents() Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
long	getBeginTimeMillis() Returns the inclusive timestamp to indicate the beginning of the range of events.
long	getEndTimeMillis() Returns the exclusive timpstamp to indicate the end of the range of events.
int[]	getEventTypes() Retrieves the usage event types for the query.
Set<String>	getPackageNames() Retrieves a Set of package names for the query.
void	writeToParcel(Parcel dest, int flags) Flatten this object in to a Parcel.

Inherited methods
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.
From interface android.os.Parcelable abstract int describeContents() Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. abstract void writeToParcel(Parcel dest, int flags) Flatten this object in to a Parcel.

Fields

CREATOR

Added in API level 35

public static final Creator<UsageEventsQuery> CREATOR

Public methods

describeContents

Added in API level 35

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
int	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or CONTENTS_FILE_DESCRIPTOR

getBeginTimeMillis

Added in API level 35

public long getBeginTimeMillis ()

Returns the inclusive timestamp to indicate the beginning of the range of events. Defined in terms of "Unix time", see System.currentTimeMillis().
Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

Returns
long	Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

getEndTimeMillis

Added in API level 35

public long getEndTimeMillis ()

Returns the exclusive timpstamp to indicate the end of the range of events. Defined in terms of "Unix time", see System.currentTimeMillis().
Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

Returns
long	Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

getEventTypes

Added in API level 35

public int[] getEventTypes ()

Retrieves the usage event types for the query.

Note that an empty array indicates querying all usage event types, and it may cause additional system overhead when calling UsageStatsManager#queryEvents(UsageEventsQuery). Apps are encouraged to provide a list of event types via Builder#setEventTypes(int...)

Returns

int[]

an array contains the usage event types that was previously set using Builder#setEventTypes(int...) or an empty array if no value has been set. 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

getPackageNames

Added in API level 35

public Set<String> getPackageNames ()

Retrieves a Set of package names for the query.

Note that an empty set indicates querying usage events for all packages, and it may cause additional system overhead when calling UsageStatsManager#queryEvents(UsageEventsQuery). Apps are encouraged to provide a list of package names via Builder#setPackageNames(String...)

Returns
Set<String>	a Set contains the package names that was previously set through Builder#setPackageNames(String...) or an empty set if no value has been set. This value cannot be null.

writeToParcel

Added in API level 35

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
dest	Parcel: This value cannot be null.
flags	int: Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
