MidiDeviceInfo
class MidiDeviceInfo : Parcelable
| kotlin.Any | |
| ↳ | android.media.midi.MidiDeviceInfo |
This class contains information to describe a MIDI device. For now we only have information that can be retrieved easily for USB devices, but we will probably expand this in the future. This class is just an immutable object to encapsulate the MIDI device description. Use the MidiDevice class to actually communicate with devices.

array of PortInfo |
getProperties
fun getProperties(): Bundle!
Returns the android.os.Bundle containing the device's properties.
| Return | |
|---|---|
Bundle! |
the device's properties |
getType
fun getType(): Int
Returns the type of the device.

|---|---|
Int |
the device's type |
isPrivate
fun isPrivate(): Boolean

|---|---|
Boolean |
true if the device is private |
toString
fun toString(): String
| Return | |
|---|---|
String |
a string representation of the object. |
writeToParcel
fun writeToParcel(
parcel: Parcel,
flags: Int
): Unit
| Parameters | |
|---|---|
dest |
The Parcel in which the object should be written. This value cannot be null. |
flags |
Int: Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE. Value is either 0 or a combination of android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
