Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Constructors

public UsageStats (UsageStats stats)

Added in API level 21

Public Methods

public void add (UsageStats right)

Added in API level 21

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

Parameters

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

Throws

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

public int describeContents ()

Added in API level 21

Describe the kinds of special objects contained in this Parcelable's marshalled representation.

Returns

a bitmask indicating the set of special object types marshalled by the Parcelable.

public long getFirstTimeStamp ()

Added in API level 21

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

See currentTimeMillis().

public long getLastTimeStamp ()

Added in API level 21

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

See currentTimeMillis().

public long getLastTimeUsed ()

Added in API level 21

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

See currentTimeMillis().

public String getPackageName ()

Added in API level 21

public long getTotalTimeInForeground ()

Added in API level 21

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

public void writeToParcel (Parcel dest, int flags)

Added in API level 21

Flatten this object in to a Parcel.

Parameters

dest	The Parcel in which the object should be written.
flags	Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`.
