Kotlin |Java

public final class UsageStats
extends Object implements Parcelable

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

Contains usage statistics for an app package for a specific time range.

Summary

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<UsageStats>`	`CREATOR`

Public constructors
`UsageStats(UsageStats stats)`

Public methods
`void`	`add(UsageStats right)` Add the statistics from the right `UsageStats` to the left.
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`long`	`getFirstTimeStamp()` Get the beginning of the time range this `UsageStats` represents, measured in milliseconds since the epoch.
`long`	`getLastTimeForegroundServiceUsed()` Get the last time this package's foreground service was used, measured in milliseconds since the epoch.
`long`	`getLastTimeStamp()` Get the end of the time range this `UsageStats` represents, measured in milliseconds since the epoch.
`long`	`getLastTimeUsed()` Get the last time this package's activity was used, measured in milliseconds since the epoch.
`long`	`getLastTimeVisible()` Get the last time this package's activity is visible in the UI, measured in milliseconds since the epoch.
`String`	`getPackageName()`
`long`	`getTotalTimeForegroundServiceUsed()` Get the total time this package's foreground services are started, measured in milliseconds.
`long`	`getTotalTimeInForeground()` Get the total time this package spent in the foreground, measured in milliseconds.
`long`	`getTotalTimeVisible()` Get the total time this package's activity is visible in the UI, measured in milliseconds.
`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 21

public static final Creator<UsageStats> CREATOR

Public constructors

UsageStats

Added in API level 21

public UsageStats (UsageStats stats)

Parameters
`stats`	`UsageStats`

Public methods

add

Added in API level 21

public void add (UsageStats right)

Add the statistics from the right UsageStats to the left. The package name for both UsageStats objects must be the same.

Parameters
`right`	`UsageStats`: The `UsageStats` object to merge into this one.

Throws
`IllegalArgumentException`	if the package names of the two `UsageStats` objects are different.

describeContents

Added in API level 21

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`

getFirstTimeStamp

Added in API level 21

public long getFirstTimeStamp ()

Get the beginning of the time range this UsageStats represents, measured in milliseconds since the epoch.

See System#currentTimeMillis().

Returns
`long`

getLastTimeForegroundServiceUsed

Added in API level 29

public long getLastTimeForegroundServiceUsed ()

Get the last time this package's foreground service was used, measured in milliseconds since the epoch.

See System#currentTimeMillis().

Returns
`long`

getLastTimeStamp

Added in API level 21

public long getLastTimeStamp ()

Get the end of the time range this UsageStats represents, measured in milliseconds since the epoch.

See System#currentTimeMillis().

Returns
`long`

getLastTimeUsed

Added in API level 21

public long getLastTimeUsed ()

Get the last time this package's activity was used, measured in milliseconds since the epoch.

See System#currentTimeMillis().

Returns
`long`

getLastTimeVisible

Added in API level 29

public long getLastTimeVisible ()

Get the last time this package's activity is visible in the UI, measured in milliseconds since the epoch.

Returns
`long`

getPackageName

Added in API level 21

public String getPackageName ()

Returns
`String`

getTotalTimeForegroundServiceUsed

Added in API level 29

public long getTotalTimeForegroundServiceUsed ()

Get the total time this package's foreground services are started, measured in milliseconds.

Returns
`long`

getTotalTimeInForeground

Added in API level 21

public long getTotalTimeInForeground ()

Get the total time this package spent in the foreground, measured in milliseconds. When in the foreground, the user is actively interacting with the app.

Returns
`long`

getTotalTimeVisible

Added in API level 29

public long getTotalTimeVisible ()

Get the total time this package's activity is visible in the UI, measured in milliseconds. Note: An app may be visible but not considered foreground. Apps in the foreground must be visible, so visible time includes time in the foreground.

Returns
`long`

writeToParcel

Added in API level 21

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: The Parcel in which the object should be written. 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
