Public methods
describeContents
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
public List<AvailableNfcAntenna> getAvailableNfcAntennas ()
Get all NFC antennas that exist on the device.
Returns | |
---|---|
List<AvailableNfcAntenna> |
This value cannot be null . |
getDeviceHeight
public int getDeviceHeight ()
Height of the device in millimeters.
Returns | |
---|---|
int |
getDeviceWidth
public int getDeviceWidth ()
Width of the device in millimeters.
Returns | |
---|---|
int |
isDeviceFoldable
public boolean isDeviceFoldable ()
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.
Returns | |
---|---|
boolean |
writeToParcel
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 |
