Remarks

Dispatcher to register OnBackInvokedCallback instances for handling back invocations.

It also provides interfaces to update the attributes of OnBackInvokedCallback. Attribute updates are proactively pushed to the window manager if they change the dispatch target (a.k.a. the callback to be invoked next), or its behavior.

Fields

PriorityDefault	Default priority level of `OnBackInvokedCallback`s.
PriorityOverlay	Priority level of `OnBackInvokedCallback`s for overlays such as menus and navigation drawers that should receive back dispatch before non-overlays.

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)
RegisterOnBackInvokedCallback(Int32, IOnBackInvokedCallback)	Registers a `OnBackInvokedCallback`.
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)
UnregisterOnBackInvokedCallback(IOnBackInvokedCallback)	Unregisters a `OnBackInvokedCallback`.

Extension Methods

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