Descriptor bit used with `https://developer.android.com/reference/android/os/Parcelable#describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int` `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE`

Flag for use with `https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`: 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

### CREATOR

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static final Creator<CredentialDescription> CREATOR
```

<br />

<br />

## Public constructors

### CredentialDescription

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

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

Constructs a `https://developer.android.com/reference/android/credentials/CredentialDescription`.

<br />

| Parameters ||
|---|---|
| `type` | `String`: the type of the credential returned. This value cannot be `null`. <br /> |
| `supportedElementKeys` | `Set`: Keys of elements to match with Credential requests. This value cannot be `null`. <br /> |
| `credentialEntries` | `List`: a list of `https://developer.android.com/reference/android/service/credentials/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 `https://developer.android.com/reference/android/app/PendingIntent` that will be invoked if the user selects this entry. This value cannot be `null`. <br /> |

| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/IllegalArgumentException` | If type is empty. |

## Public methods

### describeContents

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
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 `https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)`, the return value of this method must include the `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` bit.

<br />

| Returns ||
|---|---|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or - `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR` |

### equals

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean equals (Object obj)
```

`https://developer.android.com/reference/android/credentials/CredentialDescription#getType()` and `https://developer.android.com/reference/android/credentials/CredentialDescription#getSupportedElementKeys()` are enough for equality check.

<br />

| Parameters ||
|---|---|
| `obj` | `Object`: the reference object with which to compare. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise. <br /> |

### getCredentialEntries

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public List<CredentialEntry> getCredentialEntries ()
```

Returns the credential entries to be used in the UI.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/util/List<https://developer.android.com/reference/android/service/credentials/CredentialEntry>` | This value cannot be `null`. <br /> |

### getSupportedElementKeys

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public Set<String> getSupportedElementKeys ()
```

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

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/util/Set<https://developer.android.com/reference/java/lang/String>` | This value cannot be `null`. <br /> |

### getType

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String getType ()
```

Returns the type of the Credential described.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | This value cannot be `null`. <br /> |

### hashCode

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int hashCode ()
```

`https://developer.android.com/reference/android/credentials/CredentialDescription#getType()` and `https://developer.android.com/reference/android/credentials/CredentialDescription#getSupportedElementKeys()` are enough for hashing. Constructor enforces `https://developer.android.com/reference/android/service/credentials/CredentialEntry` to have the same type and `https://developer.android.com/reference/android/app/slice/Slice` contained by the entry can not be hashed.

<br />

| Returns ||
|---|---|
| `int` | a hash code value for this object. <br /> |

### writeToParcel

Added in [API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public void writeToParcel (Parcel dest, 
                int flags)
```
