*** ** * ** ***
An action defined by the provider that intents into the provider's app for specific user actions.
If user selects this action entry, the corresponding[PendingIntent](https://developer.android.com/reference/android/app/PendingIntent)set on the`slice`as a[ERROR(/androidx.slice.core.SliceAction)](https://developer.android.com/)will get invoked.

## Fields
### CREATOR
Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public static final Creator CREATOR
```
## Public constructors
### Action
Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public Action (Slice slice)
```
Constructs an action to be displayed on the UI.
Actions must be used for any provider related operations, such as opening the provider app, intenting straight into certain app activities like 'manage credentials', top level authentication before displaying any content etc.
See details on usage of`Action`for various actionable entries in[BeginCreateCredentialResponse](https://developer.android.com/reference/android/service/credentials/BeginCreateCredentialResponse)and[BeginGetCredentialResponse](https://developer.android.com/reference/android/service/credentials/BeginGetCredentialResponse).
| Parameters ||
|---------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `slice` | `Slice`: the slice containing the metadata to be shown on the UI, must be constructed through the[androidx.credentials.provider](https://developer.android.com/reference/androidx/credentials/provider/package-summary)Jetpack library; If constructed manually, the`slice`object must contain the non-null properties of the[Action](https://developer.android.com/reference/androidx/credentials/provider/Action.html)class populated as slice items against specific hints as used in the class's`toSlice`method, since the Android System uses this library to parse the`slice`and extract the required attributes

## 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[writeToParcel(android.os.Parcel, int)](https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)), the return value of this method must include the[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#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](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)
|
### getSlice
Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
public Slice getSlice ()
```
Returns a`Slice`object containing the display content to be displayed on the UI.
| Returns ||
|--------------------------------------------------------------------------|------------------------------------|
| [Slice](https://developer.android.com/reference/android/app/slice/Slice) | This value cannot be`null`.
|
### writeToParcel
Added in[API level 34](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)
```
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](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE). Value is either`0`or a combination of[Parcelable.PARCELABLE_WRITE_RETURN_VALUE](https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE), and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
