NfcAdapter.ICreateNdefMessageCallback Interface

Definition

Namespace:

Android.Nfc

Assembly:

Mono.Android.dll

A callback to be invoked when another NFC device capable of NDEF push (Android Beam) is within range.

Remarks

A callback to be invoked when another NFC device capable of NDEF push (Android Beam) is within range.

Implement this interface and pass it to NfcAdapter#setNdefPushMessageCallback setNdefPushMessageCallback() in order to create an NdefMessage at the moment that another device is within range for NFC. Using this callback allows you to create a message with data that might vary based on the content currently visible to the user. Alternatively, you can call #setNdefPushMessage setNdefPushMessage() if the NdefMessage always contains the same data.

This member is deprecated. this feature is removed. File sharing can work using other technology like Bluetooth.

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

CreateNdefMessage(NfcEvent)	Called to provide a NdefMessage to push.
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)
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.
