<br />

*** ** * ** ***

Details for a specific "association" that has been established between an app and companion
device.


An association gives an app the ability to interact with a companion device without needing to
acquire broader runtime permissions. An association only exists after the user has confirmed that
an app should have access to a companion device.

## Summary

### Inherited constants

From interface `https://developer.android.com/reference/android/os/Parcelable` `int` `https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR`

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.

## Fields

### CREATOR

Added in [API level 33](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

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

<br />

<br />

## Public methods

### describeContents

Added in [API level 33](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 33](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 /> |

### getAssociatedDevice

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

```
public AssociatedDevice getAssociatedDevice ()
```

Companion device that was associated. Note that this field is not persisted across sessions.
Device can be one of the following types:

- for classic Bluetooth - `https://developer.android.com/reference/android/companion/AssociatedDevice#getBluetoothDevice()`
- for Bluetooth LE - `https://developer.android.com/reference/android/companion/AssociatedDevice#getBleDevice()`

### getAssociationToken

Added in [version 37.2](https://developer.android.com/topic/libraries/support-library/revisions)

```
public UUID getAssociationToken ()
```

Association owner app can give this token to other apps to execute actions e.g. request remote
device authentication on this association without revealing the actual association
information. This token is automatically refreshed whenever the companion app calls
`https://developer.android.com/reference/android/companion/CompanionDeviceManager#createAndSetDeviceId(int,%20android.companion.DeviceId)`.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/util/UUID` | A system generated token for this association. This value cannot be `null`. <br /> |

|---|---|

### hashCode

Added in [API level 33](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 /> |

### isRemoteAiAgentSupported

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

```
public boolean isRemoteAiAgentSupported ()
```

<br />

<br />

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

**See also:**

- `https://developer.android.com/reference/android/companion/AssociationRequest.Builder#setRemoteAiAgentSupported(boolean)`

### isSelfManaged

Added in [API level 35](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean isSelfManaged ()
```

<br />

<br />

| Returns ||
|---|---|
| `boolean` | whether the association is managed by the companion application it belongs to. <br /> |

**See also:**

- `https://developer.android.com/reference/android/companion/AssociationRequest.Builder#setSelfManaged(boolean)`

### isTrusted

Added in [version 37.2](https://developer.android.com/topic/libraries/support-library/revisions)

```

```

<br />

A trusted device is a device that has been verified as user-owned via a combination of
successful secure connection establishment as well as an internal handshake involving a
direct user confirmation (e.g. Displayed PIN comparison).

<br />

<br />

| Returns ||
|---|---|
| `boolean` | True if the device had successfully verified its connection. False otherwise. <br /> |

**See also:**

public String toString ()
```

Returns a string representation of the object.

<br />

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

```
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` |
