Remarks
DragAndDropPermissions controls the access permissions for the content URIs associated with a DragEvent.
Permission are granted when this object is created by android.app.Activity#requestDragAndDropPermissions(DragEvent) Activity.requestDragAndDropPermissions. Which permissions are granted is defined by the set of flags passed to View#startDragAndDrop(android.content.ClipData, View.DragShadowBuilder, Object, int) View.startDragAndDrop by the app that started the drag operation.
The lifecycle of the permissions is bound to the activity used to call android.app.Activity#requestDragAndDropPermissions(DragEvent) 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.

Properties
| Name | Description |
|---|---|
| Class |
Returns the runtime class of this |
| Creator |
Gets the Parcelable creator used to reconstruct this type from a Parcel. |
| Handle |
The handle to the underlying Android instance. (Inherited from Object) |
| JniIdentityHashCode |
Gets the identity hash code assigned to this Java peer by the interop runtime. (Inherited from Object) |
| JniManagedPeerState | (Inherited from JavaObject) |
| JniPeerMembers |
Gets the JNI peer metadata used by the .NET for Android binding runtime. |
| PeerReference |

Methods
| Name | Description |
|---|---|
| Clone() |
Creates and returns a copy of this object. (Inherited from Object) |
| Construct(JniObjectReference, JniObjectReferenceOptions) | (Inherited from JavaObject) |
| 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(Parcel,int) , the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit. |

| Equals(Object) | (Inherited from JavaObject) |
| Equals(Object) |
Indicates whether some other object is "equal to" this one. (Inherited from Object) |
| GetHashCode() |
Returns a hash code value for the object. (Inherited from Object) |
| JavaFinalize() |
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. (Inherited from Object) |
| Notify() |
Wakes up a single thread that is waiting on this object's monitor. (Inherited from Object) |
| NotifyAll() |
Wakes up all threads that are waiting on this object's monitor. (Inherited from Object) |
| Release() |
Revoke permissions explicitly. |
| SetHandle(IntPtr, JniHandleOwnership) |
Sets the Handle property. (Inherited from Object) |
| SetPeerReference(JniObjectReference, JniObjectReferenceOptions) | (Inherited from JavaObject) |
| ToArray<T>() |
Creates a managed array from this Java array wrapper. (Inherited from Object) |
| ToString() |
Returns a string representation of the object. (Inherited from Object) |
| UnregisterFromRuntime() |
Unregisters this Java peer from the interop runtime. (Inherited from Object) |
| Wait() |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>. (Inherited from Object) |
| Wait(Int64, Int32) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
| Wait(Int64) |
Causes the current thread to wait until it is awakened, typically by being <em>notified</em> or <em>interrupted</em>, or until a certain amount of real time has elapsed. (Inherited from Object) |
