DragAndDropPermissions


public final class DragAndDropPermissions
extends Object implements Parcelable

java.lang.Object
   ↳ android.view.DragAndDropPermissions


DragAndDropPermissions controls the access permissions for the content URIs associated with a DragEvent.

Permission are granted when this object is created by Activity.requestDragAndDropPermissions. Which permissions are granted is defined by the set of flags passed to View.startDragAndDrop by the app that started the drag operation.

The lifecycle of the permissions is bound to the activity used to call requestDragAndDropPermissions. The permissions are revoked when this activity is destroyed, or when release() is called, whichever occurs first.

If you anticipate that your application will receive a large number of drops (e.g. document editor), you should try to call release() on the obtained permissions as soon as they are no longer required. Permissions can be added to your activity's Activity.onSaveInstanceState bundle and later retrieved in order to manually release the permissions once they are no longer needed.

Summary

Inherited constants

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<DragAndDropPermissions> CREATOR

Public methods

int describeContents()

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

void release()

Revoke permissions explicitly.

void writeToParcel(Parcel destination, int flags)

Flatten this object in to a Parcel.

Inherited methods

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.

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 24
public static final Creator<DragAndDropPermissions> CREATOR

Public methods

describeContents

Added in API level 24
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

release

Added in API level 24
public void release ()

Revoke permissions explicitly.

writeToParcel

Added in API level 24
public void writeToParcel (Parcel destination, 
                int flags)

Flatten this object in to a Parcel.

Parameters
destination Parcel: The Parcel in which the object should be written. 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
