getDevices
MidiDeviceInfo[] getDevices ()
Gets the list of all connected MIDI devices.
| Returns | |
|---|---|
MidiDeviceInfo[] |
an array of all MIDI devices |
openBluetoothDevice
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
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
void registerDeviceCallback (MidiManager.DeviceCallback callback, Handler handler)
Registers a callback to receive notifications when MIDI devices are added and removed.
The onDeviceStatusChanged(MidiDeviceStatus) 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 MidiManager.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
void unregisterDeviceCallback (MidiManager.DeviceCallback callback)
Unregisters a MidiManager.DeviceCallback.
| Parameters | |
|---|---|
callback |
MidiManager.DeviceCallback:
a MidiManager.DeviceCallback to unregister
|
