From interface android.os.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`	`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 was used, measured in milliseconds since the epoch.

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 millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public constructors

UsageStats

Added in API level 21

UsageStats (UsageStats stats)

Parameters
`stats`	`UsageStats`

Public methods

add

Added in API level 21

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

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(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.

getFirstTimeStamp

Added in API level 21

long getFirstTimeStamp ()

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

See currentTimeMillis().

Returns
`long`

getLastTimeStamp

Added in API level 21

long getLastTimeStamp ()

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

See currentTimeMillis().

Returns
`long`

getLastTimeUsed

Added in API level 21

long getLastTimeUsed ()

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

See currentTimeMillis().

Returns
`long`

getPackageName

Added in API level 21

String getPackageName ()

Returns
`String`

getTotalTimeInForeground

Added in API level 21

long getTotalTimeInForeground ()

Get the total time this package spent in the foreground, measured in milliseconds.

Returns
`long`

writeToParcel

Added in API level 21

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.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`.
