# AppFunctionState

*** ** * ** ***

` public final class AppFunctionState `   
` extends https://developer.android.com/reference/java/lang/Object ` ` implements https://developer.android.com/reference/android/os/Parcelable `

|---|---|
| [java.lang.Object](https://developer.android.com/reference/java/lang/Object) ||
| ↳ | android.app.appfunctions.AppFunctionState |

<br />

*** ** * ** ***

Runtime state of an app function, retrieved using `https://developer.android.com/reference/android/app/appfunctions/AppFunctionManager#getAppFunctionStates(java.util.List<android.app.appfunctions.AppFunctionName>,%20java.util.concurrent.Executor,%20android.os.OutcomeReceiver<java.util.List<android.app.appfunctions.AppFunctionState>,java.lang.Exception>)`.

This holds properties of an app function that can change at runtime during the app's operation, such as whether the function is enabled.

This is distinct from `https://developer.android.com/reference/android/app/appfunctions/AppFunctionMetadata`, which represents the metadata that remains constant until the providing package is updated. While `https://developer.android.com/reference/android/app/appfunctions/AppFunctionMetadata` defines *what* a function is, the `https://developer.android.com/reference/android/app/appfunctions/AppFunctionState` defines its current operational status.

## Fields

### CREATOR

Added in [API level 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

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

<br />

<br />

## Public methods

### describeContents

Added in [API level 37](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 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean equals (Object o)
```

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.

<br />

| Parameters ||
|---|---|
| `o` | `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 /> |

### getActivityIds

Added in [API level 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public ArraySet<AppFunctionActivityId> getActivityIds ()
```

Returns `https://developer.android.com/reference/android/app/appfunctions/AppFunctionActivityId`s this app function is associated with, or null if none.

This will only be non-null when `https://developer.android.com/reference/android/app/appfunctions/AppFunctionMetadata#getScope()` is `https://developer.android.com/reference/android/app/appfunctions/AppFunctionMetadata#SCOPE_ACTIVITY`. See `https://developer.android.com/reference/android/app/appfunctions/AppFunctionMetadata#SCOPE_ACTIVITY` for more details.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/util/ArraySet<https://developer.android.com/reference/android/app/appfunctions/AppFunctionActivityId>` | <br /> |

### getFunctionName

Added in [API level 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public AppFunctionName getFunctionName ()
```

Returns the `https://developer.android.com/reference/android/app/appfunctions/AppFunctionName` associated with this state.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/app/appfunctions/AppFunctionName` | This value cannot be `null`. <br /> |

### hashCode

Added in [API level 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int hashCode ()
```

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `https://developer.android.com/reference/java/util/HashMap`.

The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is *not* required that if two objects are unequal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

<br />

<br />

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

### isEnabled

Added in [API level 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean isEnabled ()
```

Returns whether this app function can be executed.

This can be false if:

- The app disabled the function with `https://developer.android.com/reference/android/app/appfunctions/AppFunctionManager#setAppFunctionEnabled(java.lang.String,%20int,%20java.util.concurrent.Executor,%20android.os.OutcomeReceiver<java.lang.Void,java.lang.Exception>)`.
- The function is disabled by default using `https://developer.android.com/reference/android/app/appfunctions/AppFunctionMetadata#PROPERTY_ENABLED_BY_DEFAULT` and was never enabled.
- The associated `https://developer.android.com/reference/android/app/appfunctions/AppFunctionService` is disabled.
- A function without an associated `https://developer.android.com/reference/android/app/appfunctions/AppFunctionService` has not been registered using `https://developer.android.com/reference/android/app/appfunctions/AppFunctionManager#registerAppFunction(java.lang.String,%20java.util.concurrent.Executor,%20android.app.appfunctions.AppFunction)`, or has been unregistered.
- The process registering the function using `https://developer.android.com/reference/android/app/appfunctions/AppFunctionManager#registerAppFunction(java.lang.String,%20java.util.concurrent.Executor,%20android.app.appfunctions.AppFunction)` is frozen, or the `https://developer.android.com/reference/android/content/Context` used to register it has been destroyed.

<br />

<br />

| Returns ||
|---|---|
| `boolean` | <br /> |

### toString

Added in [API level 37](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public String toString ()
```

Returns a string representation of the object.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | a string representation of the object. <br /> |

### writeToParcel

Added in [API level 37](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.

<br />

| Parameters ||
|---|---|
| `dest` | `Parcel`: This value cannot be `null`. <br /> |
| `flags` | `int`: Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of the following: - `https://developer.android.com/reference/android/os/Parcelable#PARCELABLE_WRITE_RETURN_VALUE` |
