## Public methods

### describeContents

Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
open fun describeContents(): Int
```

Implement the Parcelable interface

| Return ||
|---|---|
| `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 - `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#CONTENTS_FILE_DESCRIPTOR:kotlin.Int` |

### equals

Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
open 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` | the reference object with which to compare. |

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html` | `true` if this object is the same as the obj argument; `false` otherwise. |

### getCellConnectionStatus

```
open fun getCellConnectionStatus(): Int
```

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html` | The connection status of the cell. Value is one of the following: - `https://developer.android.com/reference/kotlin/android/telephony/CellInfo#CONNECTION_NONE:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/telephony/CellInfo#CONNECTION_PRIMARY_SERVING:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/telephony/CellInfo#CONNECTION_SECONDARY_SERVING:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/telephony/CellInfo#CONNECTION_UNKNOWN:kotlin.Int` |

```

| Return ||
|---|---|

### getTimeStamp

Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)  
Deprecated in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
open fun getTimeStamp(): Long
```

**Deprecated:** *Use `https://developer.android.com/reference/kotlin/android/telephony/CellInfo#getTimestampMillis()` instead.*

Approximate time this cell information was received from the modem.

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html` | a time stamp in nanos since boot. |

### getTimestampMillis

Added in [API level 30](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
open fun getTimestampMillis(): Long
```

Approximate time this cell information was received from the modem.   
Value is a non-negative timestamp in the `https://developer.android.com/reference/kotlin/android/os/SystemClock.html#elapsedRealtime()` time base.

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-long/index.html` | a time stamp in millis since boot. Value is a non-negative timestamp in the `https://developer.android.com/reference/kotlin/android/os/SystemClock.html#elapsedRealtime()` time base. |

### hashCode

Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
open fun hashCode(): Int
```

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/kotlin/java/util/HashMap.html#`.

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/kotlin/java/lang/Object.html#equals(kotlin.Any)` 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/kotlin/java/lang/Object.html#equals(kotlin.Any)` 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.

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html` | a hash code value for this object. |

### isRegistered

Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
open fun isRegistered(): Boolean
```

True if the phone is registered to a mobile network that provides service on this cell and this cell is being used or would be used for network signaling.

### toString

Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

```
open fun toString(): String
```

Returns a string representation of the object.

| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html` | a string representation of the object. |

### writeToParcel

Added in [API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

    dest: Parcel, 
    flags: Int

```

| `flags` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html): Additional flags about how the object should be written. May be 0 or `https://developer.android.com/reference/kotlin/android/os/Parcelable.html#PARCELABLE_WRITE_RETURN_VALUE:kotlin.Int`.
