<br />

*** ** * ** ***

Network specifier object used to request a Wi-Fi network. Apps should use the `https://developer.android.com/reference/android/net/wifi/WifiNetworkSpecifier.Builder` class to create an instance.

This specifier can be used to request a local-only connection on devices that support concurrent connections (indicated via `https://developer.android.com/reference/android/net/wifi/WifiManager#isStaConcurrencyForLocalOnlyConnectionsSupported()` and if the initiating app targets SDK ≥ `https://developer.android.com/reference/android/os/Build.VERSION_CODES#S` or is a system app. These local-only connections may be brought up as a secondary concurrent connection (primary connection will be used for networks with internet connectivity available to the user and all apps).

This specifier can also be used to listen for connected Wi-Fi networks on a particular band. Additionally, some devices may support requesting a connection to a particular band. If the device does not support such a request, it will send `https://developer.android.com/reference/android/net/ConnectivityManager.NetworkCallback#onUnavailable()` upon request to the callback passed to `https://developer.android.com/reference/android/net/ConnectivityManager#requestNetwork(android.net.NetworkRequest,%20android.net.ConnectivityManager.NetworkCallback)` or equivalent. See `https://developer.android.com/reference/android/net/wifi/WifiNetworkSpecifier.Builder#build()` for details.

## Fields

### CREATOR

Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

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

<br />

<br />

## Public methods

### canBeSatisfiedBy

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public boolean canBeSatisfiedBy (NetworkSpecifier other)
```

<br />

<br />

| Parameters ||
|---|---|
| `other` | `NetworkSpecifier` <br /> |

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

### describeContents

Added in [API level 29](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 29](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 /> |

### getBand

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public int getBand ()
```

The band for this Wi-Fi network specifier.

<br />

| Returns ||
|---|---|
| `int` | Value is one of the following: - `https://developer.android.com/reference/android/net/wifi/ScanResult#UNSPECIFIED` - `https://developer.android.com/reference/android/net/wifi/ScanResult#WIFI_BAND_24_GHZ` - `https://developer.android.com/reference/android/net/wifi/ScanResult#WIFI_BAND_5_GHZ` - `https://developer.android.com/reference/android/net/wifi/ScanResult#WIFI_BAND_6_GHZ` - `https://developer.android.com/reference/android/net/wifi/ScanResult#WIFI_BAND_60_GHZ` |

### getPreferredChannelFrequenciesMhz

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

```
public int[] getPreferredChannelFrequenciesMhz ()
```

The preferred channels fot this network specifier.

<br />

| Returns ||
|---|---|
| `int[]` | This value cannot be `null`. <br /> |

**See also:**

- `https://developer.android.com/reference/android/net/wifi/WifiNetworkSpecifier.Builder#setPreferredChannelsFrequenciesMhz(int[])`

### hashCode

Added in [API level 29](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 /> |

### redact

Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public NetworkSpecifier redact ()
```

<br />

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/android/net/NetworkSpecifier` | This value may be `null`. <br /> |

### toString

Added in [API level 29](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 29](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`: The Parcel in which the object should be written. 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` |
