UsageStats

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 timeout, 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 timeout)` 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.

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

public static final Creator<UsageStats> CREATOR

Public constructors

UsageStats

public UsageStats (UsageStats stats)

Parameters
`stats`	`UsageStats`

Public methods

add

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

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

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

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

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

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

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

public String getPackageName ()

Returns
`String`

getTotalTimeForegroundServiceUsed

public long getTotalTimeForegroundServiceUsed ()

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

Returns
`long`

getTotalTimeInForeground

public long getTotalTimeInForeground ()

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

Returns
`long`

getTotalTimeVisible

public long getTotalTimeVisible ()

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

Returns
`long`

writeToParcel

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.
`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
