# CallAttributes

*** ** * ** ***

` public final class CallAttributes `   
` 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.telecom.CallAttributes |

<br />

*** ** * ** ***

CallAttributes represents a set of properties that define a new Call. Apps should build an instance of this class and use `https://developer.android.com/reference/android/telecom/TelecomManager#addCall(android.telecom.CallAttributes,%20java.util.concurrent.Executor,%20android.os.OutcomeReceiver<android.telecom.CallControl,android.telecom.CallException>,%20android.telecom.CallControlCallback,%20android.telecom.CallEventCallback)` to start a new call with Telecom.

Apps should first register a `https://developer.android.com/reference/android/telecom/PhoneAccount` via `https://developer.android.com/reference/android/telecom/TelecomManager#registerPhoneAccount(android.telecom.PhoneAccount)` and use the same `https://developer.android.com/reference/android/telecom/PhoneAccountHandle` registered with Telecom when creating an instance of CallAttributes.

## 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)
```

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 ||
|---|---|
| `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 /> |

```
public int getCallType ()
```

<br />

<br />

### getContactUri

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

```
public Uri getContactUri ()
```

<br />

<br />

```
public int getDirection ()

### getDisplayName

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

```
public CharSequence getDisplayName ()
```

<br />

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/CharSequence` | display name of the incoming caller or the person being called for an outgoing call. This value cannot be `null`. <br /> |

### getPhoneAccountHandle

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

```
public PhoneAccountHandle getPhoneAccountHandle ()
```

<br />

| `https://developer.android.com/reference/android/telecom/PhoneAccountHandle` | the `https://developer.android.com/reference/android/telecom/PhoneAccountHandle` for this package that allows this call to be created. 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 ()
```

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 /> |

### isGroupCall

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

```
public boolean isGroupCall ()
```

<br />

<br />

| Returns ||
|---|---|
| `boolean` | Whether the call is a group call <br /> |

### isLogExcluded

Added in [version 36.1](https://developer.android.com/topic/libraries/support-library/revisions)

```
public boolean isLogExcluded ()
```

<br />

<br />

| Returns ||
|---|---|
| `boolean` | Whether the call is excluded from system call logs <br /> |

### toString

Added in [API level 34](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 /> |

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

Flatten this object in to a Parcel.

<br />

| Parameters ||
|---|---|
| `dest` | `Parcel`: This value may be `null`. <br /> |
