CredentialDescription

Kotlin |Java

public final class CredentialDescription
extends Object implements Parcelable

java.lang.Object
↳	android.credentials.CredentialDescription

Represents the type and contained data fields of a Credential.

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<CredentialDescription>`	`CREATOR`

Public constructors
`CredentialDescription(String type, Set<String> supportedElementKeys, List<CredentialEntry> credentialEntries)` Constructs a `CredentialDescription`.

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`boolean`	`equals(Object obj)` `getType()` and `getSupportedElementKeys()` are enough for equality check.
`List<CredentialEntry>`	`getCredentialEntries()` Returns the credential entries to be used in the UI.
`Set<String>`	`getSupportedElementKeys()` Returns the flattened JSON string that will be matched with requests.
`String`	`getType()` Returns the type of the Credential described.
`int`	`hashCode()` `getType()` and `getSupportedElementKeys()` are enough for hashing.
`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<CredentialDescription> CREATOR

Public constructors

CredentialDescription

Added in API level 34

public CredentialDescription (String type, 
                Set<String> supportedElementKeys, 
                List<CredentialEntry> credentialEntries)

Constructs a CredentialDescription.

Parameters
`type`	`String`: the type of the credential returned. This value cannot be `null`.
`supportedElementKeys`	`Set`: Keys of elements to match with Credential requests. This value cannot be `null`.
`credentialEntries`	`List`: a list of `CredentialEntry`s that are to be shown on the account selector if a credential matches with this description. Each entry contains information to be displayed within an entry on the UI, as well as a `PendingIntent` that will be invoked if the user selects this entry. This value cannot be `null`.

Throws
`IllegalArgumentException`	If type is empty.

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`

equals

Added in API level 34

public boolean equals (Object obj)

getType() and getSupportedElementKeys() are enough for equality check.

Parameters
`obj`	`Object`: the reference object with which to compare.

Returns
`boolean`	`true` if this object is the same as the obj argument; `false` otherwise.

getCredentialEntries

Added in API level 34

public List<CredentialEntry> getCredentialEntries ()

Returns the credential entries to be used in the UI.

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

getSupportedElementKeys

Added in API level 34

public Set<String> getSupportedElementKeys ()

Returns the flattened JSON string that will be matched with requests.

Returns
`Set<String>`	This value cannot be `null`.

getType

Added in API level 34

public String getType ()

Returns the type of the Credential described.

Returns
`String`	This value cannot be `null`.

hashCode

Added in API level 34

public int hashCode ()

getType() and getSupportedElementKeys() are enough for hashing. Constructor enforces CredentialEntry to have the same type and Slice contained by the entry can not be hashed.

Returns
`int`	a hash code value for this object.

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
