MidiManager

This class is the public application interface to the MIDI service.

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 `openDevice(MidiDeviceInfo, MidiManager.OnDeviceOpenedListener, Handler)` and `openBluetoothDevice(BluetoothDevice, MidiManager.OnDeviceOpenedListener, Handler)`

Nested Classes

class

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

Public Methods

public MidiDeviceInfo[] getDevices ()

Added in API level 23

Gets the list of all connected MIDI devices.

Returns

an array of all MIDI devices

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

Added in API level 23

Opens a Bluetooth MIDI device for reading and writing.

Parameters

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

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

Added in API level 23

Opens a MIDI device for reading and writing.

Parameters

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

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

Added in API level 23

Registers a callback to receive notifications when MIDI devices are added and removed.

Parameters

callback	a `MidiManager.DeviceCallback` for MIDI device notifications
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.
