NfcAntennaInfo

Kotlin |Java

class NfcAntennaInfo : Parcelable

kotlin.Any
↳	android.nfc.NfcAntennaInfo

Contains information on all available Nfc antennas on an Android device as well as information on the device itself in relation positioning of the antennas.

Summary

Inherited constants

From class Parcelable

Int

CONTENTS_FILE_DESCRIPTOR

Descriptor bit used with describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Int

PARCELABLE_WRITE_RETURN_VALUE

Flag for use with writeToParcel: the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Public constructors
`NfcAntennaInfo(deviceWidth: Int, deviceHeight: Int, deviceFoldable: Boolean, availableNfcAntennas: MutableList<AvailableNfcAntenna!>)`

Public methods
Int	`describeContents()`
MutableList<AvailableNfcAntenna!>	`getAvailableNfcAntennas()` Get all NFC antennas that exist on the device.
Int	`getDeviceHeight()` Height of the device in millimeters.
Int	`getDeviceWidth()` Width of the device in millimeters.
Boolean	`isDeviceFoldable()` Whether the device is foldable.
Unit	`writeToParcel(dest: Parcel, flags: Int)` Flatten this object in to a Parcel.

Properties
static Parcelable.Creator<NfcAntennaInfo!>	`CREATOR`

NfcAntennaInfo

Added in API level 34

NfcAntennaInfo(
    deviceWidth: Int, 
    deviceHeight: Int, 
    deviceFoldable: Boolean, 
    availableNfcAntennas: MutableList<AvailableNfcAntenna!>)

Parameters
`availableNfcAntennas`	MutableList<AvailableNfcAntenna!>: This value cannot be `null`.

Public methods

describeContents

Added in API level 34

fun describeContents(): Int

Return
`Int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR`

getAvailableNfcAntennas

Added in API level 34

fun getAvailableNfcAntennas(): MutableList<AvailableNfcAntenna!>

Get all NFC antennas that exist on the device.

Return
`MutableList<AvailableNfcAntenna!>`	This value cannot be `null`.

getDeviceHeight

Added in API level 34

fun getDeviceHeight(): Int

Height of the device in millimeters.

getDeviceWidth

Added in API level 34

fun getDeviceWidth(): Int

Width of the device in millimeters.

isDeviceFoldable

Added in API level 34

fun isDeviceFoldable(): Boolean

Whether the device is foldable. When the device is foldable, the 0, 0 is considered to be bottom-left when the device is unfolded and the screens are facing the user. For non-foldable devices 0, 0 is bottom-left when the user is facing the screen.

writeToParcel

Added in API level 34

fun writeToParcel(
    dest: Parcel, 
    flags: Int
): Unit

Flatten this object in to a Parcel.

Parameters
`dest`	Parcel: 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

Properties

CREATOR

Added in API level 34

static val CREATOR: Parcelable.Creator<NfcAntennaInfo!>
