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<PictureInPictureUiState>	CREATOR

Public methods
int	describeContents() Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
boolean	equals(Object o) Indicates whether some other object is "equal to" this one.
int	hashCode() Returns a hash code value for the object.
boolean	isStashed() Returns whether Picture-in-Picture is stashed or not.
boolean	isTransitioningToPip() Returns true if the app is going to enter Picture-in-Picture (PiP) mode.
void	writeToParcel(Parcel out, 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 31

public static final Creator<PictureInPictureUiState> CREATOR

Public methods

describeContents

Added in API level 31

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

equals

Added in API level 31

public boolean equals (Object o)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o	Object: the reference object with which to compare.

Returns
boolean	true if this object is the same as the obj argument; false otherwise.

hashCode

Added in API level 31

public int hashCode ()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

Returns
int	a hash code value for this object.

isStashed

Added in API level 31

public boolean isStashed ()

Returns whether Picture-in-Picture is stashed or not. A stashed PiP means it is only partially visible to the user, with some parts of it being off-screen. This is usually a UI state that is triggered by the user, such as flinging the PiP to the edge or letting go of PiP while dragging partially off-screen. Developers can use this in conjunction with Activity.onPictureInPictureUiStateChanged(PictureInPictureUiState) to get a signal when the PiP stash state has changed. For example, if the state changed from false to true, developers can choose to temporarily pause video playback if PiP is of video content. Vice versa, if changing from true to false and video content is paused, developers can resume video playback.

Returns
boolean

isTransitioningToPip

Added in API level 35

public boolean isTransitioningToPip ()

Returns true if the app is going to enter Picture-in-Picture (PiP) mode. This state is associated with the entering PiP animation. When that animation starts, whether via auto enter PiP or calling Activity.enterPictureInPictureMode(PictureInPictureParams) explicitly, app can expect Activity.onPictureInPictureUiStateChanged(PictureInPictureUiState) callback with isTransitioningToPip() to be true first, followed by Activity.onPictureInPictureModeChanged(boolean, Configuration) when it fully settles in PiP mode. When app receives the Activity.onPictureInPictureUiStateChanged(PictureInPictureUiState) callback with isTransitioningToPip() being true, it's recommended to hide certain UI elements, such as video controls, to archive a clean entering PiP animation. In case an application wants to restore the previously hidden UI elements when exiting PiP, it is recommended to do that in onPictureInPictureModeChanged(isInPictureInPictureMode=false) callback rather than the beginning of exit PiP animation.

Returns
boolean

writeToParcel

Added in API level 31

public void writeToParcel (Parcel out, 
                int flags)

Flatten this object in to a Parcel.

Parameters
out	Parcel: 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
