Remarks

Interface for applications to register back animation callbacks along their custom back handling.

This allows the client to customize various back behaviors by overriding the corresponding callback methods.

Callback instances can be added to and removed from OnBackInvokedDispatcher, which is held at window level and accessible through Activity#getOnBackInvokedDispatcher(), Dialog#getOnBackInvokedDispatcher(), Window#getOnBackInvokedDispatcher() and View#findOnBackInvokedDispatcher().

When back is triggered, callbacks on the in-focus window are invoked in reverse order in which they are added within the same priority. Between different priorities, callbacks with higher priority are invoked first.

Properties

Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
JniIdentityHashCode	Returns the value of java.lang.System.identityHashCode() for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)

Methods

Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls Dispose(); otherwise, does nothing. (Inherited from IJavaPeerable)
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
OnBackCancelled()	Called when a back gesture or back button press has been cancelled.
OnBackInvoked()	Called when a back gesture has been completed and committed, or back button pressed has been released and committed. (Inherited from IOnBackInvokedCallback)
OnBackProgressed(BackEvent)	Called when a back gesture progresses.
OnBackStarted(BackEvent)	Called when a back gesture has been started, or back button has been pressed down.
SetJniIdentityHashCode(Int32)	Set the value returned by JniIdentityHashCode. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by PeerReference. (Inherited from IJavaPeerable)
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)

Extension Methods

JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
