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

Flag for use with[writeToParcel](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#writeToParcel(android.os.Parcel,%20kotlin.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)`". Some implementations may want to release resources at this point.

| ## Public methods ### create Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` static fun create(     host: View,     virtualId: Int ): AutofillId ``` Creates an[AutofillId](https://developer.android.com/reference/kotlin/android/view/autofill/AutofillId#)with the virtual id. This method is used by a[View](https://developer.android.com/reference/kotlin/android/view/View.html#)that contains the virtual view hierarchy. Use this method to create the[AutofillId](https://developer.android.com/reference/kotlin/android/view/autofill/AutofillId#)for each virtual view. | Parameters || |-------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `host` | [View](https://developer.android.com/reference/kotlin/android/view/View.html#):the view hosting the virtual view hierarchy which is used to show autofill suggestions. This value cannot be`null`. | | `virtualId` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html):id identifying the virtual view inside the host view. | | Return || |------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------| | [AutofillId](https://developer.android.com/reference/kotlin/android/view/autofill/AutofillId#) | an[AutofillId](https://developer.android.com/reference/kotlin/android/view/autofill/AutofillId#)for the virtual view This value cannot be`null`. | ### describeContents Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun describeContents(): Int ``` | Return || |----------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either`0`or[android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int) | ### equals Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun equals(other: Any?): Boolean ``` Indicates whether some other object is "equal to" this one. The`equals`method implements an equivalence relation on non-null object references: - It is*reflexive* : for any non-null reference value`x`,`x.equals(x)`should return`true`. - It is*symmetric* : for any non-null reference values`x`and`y`,`x.equals(y)`should return`true`if and only if`y.equals(x)`returns`true`. - It is*transitive* : for any non-null reference values`x`,`y`, and`z`, if`x.equals(y)`returns`true`and`y.equals(z)`returns`true`, then`x.equals(z)`should return`true`. - It is*consistent* : for any non-null reference values`x`and`y`, multiple invocations of`x.equals(y)`consistently return`true`or consistently return`false`, provided no information used in`equals`comparisons on the objects is modified. - For any non-null reference value`x`,`x.equals(null)`should return`false`. An equivalence relation partitions the elements it operates on into*equivalence classes*; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes. | Parameters || |-------|--------------------------| | `obj` | This value may be`null`. | | Return || |------------------------------------------------------------------------------------|------------------------------------------------------------------------| | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | `true`if this object is the same as the obj argument;`false`otherwise. | ### getAutofillVirtualId Added in[API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun getAutofillVirtualId(): Int ``` Gets the virtual id. This is set if the view is a virtual view, most commonly set if the View is of[android.webkit.WebView](https://developer.android.com/reference/kotlin/android/webkit/WebView.html#). ### getSessionId Added in[API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun getSessionId(): Int ``` Used to get the Session identifier associated with this AutofillId. | Return || |----------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | a non-zero integer if[isInAutofillSession()](https://developer.android.com/reference/kotlin/android/view/autofill/AutofillId#isInAutofillSession())returns true | ### getViewId Added in[API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun getViewId(): Int ``` Returns the assigned unique identifier of this AutofillID.

This will usually return true if it should be used by an autofill service provider, and false otherwise. ### isVirtual Added in[API level 36](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun isVirtual(): Boolean ``` Checks whether this AutofillId represents a virtual view. ### toString Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun toString(): String ``` | Return || |----------------------------------------------------------------------------------|----------------------------------------| | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html) | a string representation of the object. | ### writeToParcel Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun writeToParcel(     parcel: Parcel,     flags: Int ): Unit ``` | Parameters || |---------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `dest` | The Parcel in which the object should be written.

Value is either`0`or a combination of[android.os.Parcelable#PARCELABLE_WRITE_RETURN_VALUE](https://developer.android.com/reference/kotlin/android/os/Parcelable.html#PARCELABLE_WRITE_RETURN_VALUE:kotlin.Int), and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES | ## Properties ### CREATOR Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` static val CREATOR: Parcelable.Creator ```
