VerifiedDisplayHash

Added in API level 31
public VerifiedDisplayHash (long timeMillis, 
                Rect boundsInWindow, 
                String hashAlgorithm, 
                byte[] imageHash)

Creates a new VerifiedDisplayHash.

Parameters
timeMillis long: The timestamp when the hash was generated. Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

boundsInWindow Rect: The bounds of the requested area to generate the hash. This is in window space passed in by the client. This value cannot be null.

hashAlgorithm String: The selected hash algorithm that generated the image hash. This value cannot be null.

imageHash byte: The image hash generated when creating the DisplayHash. This value cannot be null.

Public methods

describeContents

Added in API level 31
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

getBoundsInWindow

Added in API level 31
public Rect getBoundsInWindow ()

The bounds of the requested area to generate the hash. This is in window space passed in by the client.

Returns
Rect This value cannot be null.

getHashAlgorithm

Added in API level 31
public String getHashAlgorithm ()

The selected hash algorithm that generated the image hash.

Returns
String This value cannot be null.

getImageHash

Added in API level 31
public byte[] getImageHash ()

The image hash generated when creating the DisplayHash.

Returns
byte[] This value cannot be null.

getTimeMillis

Added in API level 31
public long getTimeMillis ()

The timestamp when the hash was generated.
Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

Returns
long Value is a non-negative timestamp measured as the number of milliseconds since 1970-01-01T00:00:00Z.

toString

Added in API level 31
public String toString ()

Returns a string representation of the object.

Returns
String a string representation of the object.

writeToParcel

Added in API level 31
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
