RegisterDeviceCallback(Int32, IExecutor, MidiManager+DeviceCallback)

Registers a callback to receive notifications when MIDI devices are added and removed for a specific transport type.

[Android.Runtime.Register("registerDeviceCallback", "(ILjava/util/concurrent/Executor;Landroid/media/midi/MidiManager$DeviceCallback;)V", "", ApiSince=33)]
public void RegisterDeviceCallback(int transport, Java.Util.Concurrent.IExecutor executor, Android.Media.Midi.MidiManager.DeviceCallback callback);

[<Android.Runtime.Register("registerDeviceCallback", "(ILjava/util/concurrent/Executor;Landroid/media/midi/MidiManager$DeviceCallback;)V", "", ApiSince=33)>]
member this.RegisterDeviceCallback : int * Java.Util.Concurrent.IExecutor * Android.Media.Midi.MidiManager.DeviceCallback -> unit

Parameters

transport: Int32

The transport to be used. This is either TRANSPORT_MIDI_BYTE_STREAM or TRANSPORT_UNIVERSAL_MIDI_PACKETS. Value is one of the following: TRANSPORT_MIDI_BYTE_STREAM; TRANSPORT_UNIVERSAL_MIDI_PACKETS

executor: IExecutor

The Executor that will be used for delivering the device notifications. This value cannot be null.

callback: MidiManager.DeviceCallback

a DeviceCallback for MIDI device notifications. This value cannot be null.

Attributes: RegisterAttribute

Remarks

Registers a callback to receive notifications when MIDI devices are added and removed for a specific transport type. The DeviceCallback.onDeviceStatusChanged method will be called immediately for any devices that have open ports. This allows applications to know which input ports are already in use and, therefore, unavailable. Applications should call getDevicesForTransport(int) before registering the callback to get a list of devices already added.
