IComponentCallbacks Interface

Definition

The set of callback APIs that are common to all application components (android.app.Activity, android.app.Service, ContentProvider, and android.app.Application).

[Android.Runtime.Register("android/content/ComponentCallbacks", "", "Android.Content.IComponentCallbacksInvoker")]
public interface IComponentCallbacks : Android.Runtime.IJavaObject, IDisposable, Java.Interop.IJavaPeerable
[<Android.Runtime.Register("android/content/ComponentCallbacks", "", "Android.Content.IComponentCallbacksInvoker")>]
type IComponentCallbacks = interface
    interface IJavaObject

Remarks

The set of callback APIs that are common to all application components (android.app.Activity, android.app.Service, ContentProvider, and android.app.Application).

<p class="note"><strong>Note:</strong> You should also implement the ComponentCallbacks2 interface, which provides the ComponentCallbacks2#onTrimMemory callback to help your app manage its memory usage more effectively.</p>

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)
OnConfigurationChanged(Configuration)

Called by the system when the device configuration changes while your component is running.

OnLowMemory()

This is called when the overall system is running low on memory, and actively running processes should trim their memory usage.

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)
