NfcAntennaInfo

Added in API level 34
public NfcAntennaInfo (int deviceWidth, 
                int deviceHeight, 
                boolean deviceFoldable, 
                List<AvailableNfcAntenna> availableNfcAntennas)

Parameters
deviceWidth 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(android.os.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
public boolean isDeviceFoldable ()

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 Parcelable.PARCELABLE_WRITE_RETURN_VALUE, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
