NfcAntennaInfo

Kotlin |Java

public final class NfcAntennaInfo
extends Object implements Parcelable

java.lang.Object
↳	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 interface android.os.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(Parcel, int)`: 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)`".

Fields
`public static final Creator<NfcAntennaInfo>`	`CREATOR`

Public constructors
`NfcAntennaInfo(int deviceWidth, int deviceHeight, boolean deviceFoldable, List<AvailableNfcAntenna> availableNfcAntennas)`

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`List<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()` This method was deprecated in API level 37. This method is deprecated and no longer maintained.
`void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

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 timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

From interface


        
          android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Fields

CREATOR

Added in API level 34

public static final Creator<NfcAntennaInfo> CREATOR

Public constructors

NfcAntennaInfo

Added in API level 34

public NfcAntennaInfo (int deviceWidth, 
                int deviceHeight, 
                boolean deviceFoldable, 
                List<AvailableNfcAntenna> availableNfcAntennas)

Parameters
`deviceWidth`	`int`
`deviceHeight`	`int`
`deviceFoldable`	`boolean`
`availableNfcAntennas`	`List`: This value cannot be `null`.

Public methods

describeContents

Added in API level 34

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(Parcel,int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

getAvailableNfcAntennas

Added in API level 34

public List<AvailableNfcAntenna> getAvailableNfcAntennas ()

Get all NFC antennas that exist on the device.

Returns
`List<AvailableNfcAntenna>`	This value cannot be `null`.

getDeviceHeight

Added in API level 34

public int getDeviceHeight ()

Height of the device in millimeters.

Returns
`int`

getDeviceWidth

Added in API level 34

public int getDeviceWidth ()

Width of the device in millimeters.

Returns
`int`

isDeviceFoldable

Added in API level 34
Deprecated in API level 37

public boolean isDeviceFoldable ()

This method was deprecated in API level 37.
This method is deprecated and no longer maintained.

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

Returns
`boolean`

writeToParcel

Added in API level 34

public void writeToParcel (Parcel dest, 
                int flags)

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.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`
