MidiManager

public final class MidiManager
extends Object

java.lang.Object
↳	android.media.midi.MidiManager

This class is the public application interface to the MIDI service.
Requires the PackageManager#FEATURE_MIDI feature which can be detected using PackageManager.hasSystemFeature(String).

Summary

Nested classes
`class`	`MidiManager.DeviceCallback` Callback class used for clients to receive MIDI device added and removed notifications
`interface`	`MidiManager.OnDeviceOpenedListener` Listener class used for receiving the results of `MidiManager.openDevice(MidiDeviceInfo, MidiManager.OnDeviceOpenedListener, Handler)` and `MidiManager.openBluetoothDevice(BluetoothDevice, MidiManager.OnDeviceOpenedListener, Handler)`

Public methods
`MidiDeviceInfo[]`	`getDevices()` Gets the list of all connected MIDI devices.
`void`	`openBluetoothDevice(BluetoothDevice bluetoothDevice, MidiManager.OnDeviceOpenedListener listener, Handler handler)` Opens a Bluetooth MIDI device for reading and writing.
`void`	`openDevice(MidiDeviceInfo deviceInfo, MidiManager.OnDeviceOpenedListener listener, Handler handler)` Opens a MIDI device for reading and writing.
`void`	`registerDeviceCallback(MidiManager.DeviceCallback callback, Handler handler)` Registers a callback to receive notifications when MIDI devices are added and removed.
`void`	`unregisterDeviceCallback(MidiManager.DeviceCallback callback)` Unregisters a `DeviceCallback`.

Inherited methods

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public methods

getDevices

public MidiDeviceInfo[] getDevices ()

Gets the list of all connected MIDI devices.

Returns
`MidiDeviceInfo[]`	an array of all MIDI devices

openBluetoothDevice

public void openBluetoothDevice (BluetoothDevice bluetoothDevice, 
                MidiManager.OnDeviceOpenedListener listener, 
                Handler handler)

Opens a Bluetooth MIDI device for reading and writing.

Parameters
`bluetoothDevice`	`BluetoothDevice`: a `BluetoothDevice` to open as a MIDI device
`listener`	`MidiManager.OnDeviceOpenedListener`: a `MidiManager.OnDeviceOpenedListener` to be called to receive the result
`handler`	`Handler`: the `Handler` that will be used for delivering the result. If handler is null, then the thread used for the listener is unspecified.

openDevice

public void openDevice (MidiDeviceInfo deviceInfo, 
                MidiManager.OnDeviceOpenedListener listener, 
                Handler handler)

Opens a MIDI device for reading and writing.

Parameters
`deviceInfo`	`MidiDeviceInfo`: a `MidiDeviceInfo` to open
`listener`	`MidiManager.OnDeviceOpenedListener`: a `MidiManager.OnDeviceOpenedListener` to be called to receive the result
`handler`	`Handler`: the `Handler` that will be used for delivering the result. If handler is null, then the thread used for the listener is unspecified.

registerDeviceCallback

public void registerDeviceCallback (MidiManager.DeviceCallback callback, 
                Handler handler)

Registers a callback to receive notifications when MIDI devices are added and removed. 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 getDevices() before registering the callback to get a list of devices already added.

Parameters
`callback`	`MidiManager.DeviceCallback`: a `DeviceCallback` for MIDI device notifications
`handler`	`Handler`: The `Handler` that will be used for delivering the device notifications. If handler is null, then the thread used for the callback is unspecified.

unregisterDeviceCallback

public void unregisterDeviceCallback (MidiManager.DeviceCallback callback)

Unregisters a DeviceCallback.

Parameters
`callback`	`MidiManager.DeviceCallback`: a `DeviceCallback` to unregister
