ParcelFileDescriptor	The FileDescriptor returned by readFileDescriptor(), allowing you to close it when done with it.
ParcelableSpan	A special kind of Parcelable for objects that will serve as text spans.
PatternMatcher	A simple pattern matcher, which is safe to use on untrusted data: it does not provide full reg-exp support, only simple globbing that can not be used maliciously.
PendingIntent	A description of an Intent and target action to perform with it.
PermissionGroupInfo	Information you can retrieve about a particular security permission group known to the system.
PermissionInfo	Information you can retrieve about a particular security permission known to the system.

WifiInfo	Describes the state of any Wifi connection that is active or is in the process of being set up.
WindowManager.LayoutParams

Class Overview

Interface for classes whose instances can be written to and restored from a Parcel. Classes implementing the Parcelable interface must also have a static field called CREATOR, which is an object implementing the Parcelable.Creator interface.

A typical implementation of Parcelable is:

 public class MyParcelable implements Parcelable {
     private int mData;
     
     public void writeToParcel(Parcel out, int flags) {
         out.writeInt(mData);
     }

     public static final Parcelable.Creator CREATOR
             = new Parcelable.Creator() {
         public MyParcelable createFromParcel(Parcel in) {
             return new MyParcelable(in);
         }

         public MyParcelable[] newArray(int size) {
             return new MyParcelable[size];
         }
     }
     
     private MyParcelable(Parcel in) {
         mData = in.readInt();
     }
 }

Summary

Nested Classes
public interface	Parcelable.Creator<T>	Interface that must be implemented and provided as a public CREATOR field that generates instances of your Parcelable class from a Parcel.

Constants
int	CONTENTS_FILE_DESCRIPTOR	Bit masks for use with describeContents(): each bit represents a kind of object considered to have potential special significance when marshalled.
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)`".

Public Methods
abstract int	describeContents() Describe the kinds of special objects contained in this Parcelable's marshalled representation.
abstract void	writeToParcel(Parcel dest, int flags) Flatten this object in to a Parcel.

Constants

public static final int CONTENTS_FILE_DESCRIPTOR

Bit masks for use with describeContents(): each bit represents a kind of object considered to have potential special significance when marshalled.

Constant Value: 1 (0x00000001)

public static final 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)". Some implementations may want to release resources at this point.

Constant Value: 1 (0x00000001)

Public Methods

public abstract int describeContents ()

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 abstract void writeToParcel (Parcel dest, int flags)

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.
