*** ** * ** ***

An object describing a network that the application is interested in.

@see[](https://developer.android.com/training/basics/network-ops/reading-network-state> this general guide</a> on how to use NetworkCapabilities and related classes. NetworkRequest defines a request for a network, made through <code translate=)[NetworkRequest.Builder](https://developer.android.com/reference/android/net/NetworkRequest.Builder)and used to request a network via[ConnectivityManager.requestNetwork](https://developer.android.com/reference/android/net/ConnectivityManager#requestNetwork(android.net.NetworkRequest,%20android.app.PendingIntent))or to listen for changes via the[ConnectivityManager.registerNetworkCallback](https://developer.android.com/reference/android/net/ConnectivityManager#registerNetworkCallback(android.net.NetworkRequest,%20android.app.PendingIntent))family of functions.

[ConnectivityManager.requestNetwork](https://developer.android.com/reference/android/net/ConnectivityManager#requestNetwork(android.net.NetworkRequest,%20android.app.PendingIntent))will try to find a connected network matching the NetworkRequest, and return it if there is one. As long as the request is outstanding, the system will try to find the best possible network that matches the request. The request will keep up the currently best connected network, and if a better one is found (e.g. cheaper or faster) the system will bring up that better network to better serve the request. A request filed with[ConnectivityManager.requestNetwork](https://developer.android.com/reference/android/net/ConnectivityManager#requestNetwork(android.net.NetworkRequest,%20android.app.PendingIntent))will only match one network at a time (the one the system thinks is best), even if other networks can match the request that are being kept up by other requests. For example, an application needing a network with[NetworkCapabilities.NET_CAPABILITY_INTERNET](https://developer.android.com/reference/android/net/NetworkCapabilities#NET_CAPABILITY_INTERNET)should use[ConnectivityManager.requestNetwork](https://developer.android.com/reference/android/net/ConnectivityManager#requestNetwork(android.net.NetworkRequest,%20android.app.PendingIntent))to request the system keeps one up. A general cellular network can satisfy this request, but if the system finds a free Wi-Fi network which is expected to be faster, it will try and connect to that Wi-Fi network and switch the request over to it once it is connected. The cell network may stay connected if there are outstanding requests (from the same app or from other apps on the system) that match the cell network but not the Wi-Fi network, such as a request with[NetworkCapabilities.NET_CAPABILITY_MMS](https://developer.android.com/reference/android/net/NetworkCapabilities#NET_CAPABILITY_MMS). When a network is no longer needed to serve any request, the system can tear it down at any time and usually does so immediately, so make sure to keep up requests for the networks your app needs.

By contrast, requests filed with[ConnectivityManager.registerNetworkCallback](https://developer.android.com/reference/android/net/ConnectivityManager#registerNetworkCallback(android.net.NetworkRequest,%20android.app.PendingIntent))will receive callbacks for all matching networks, and will not cause the system to keep up the networks they match. Use this to listen to networks that the device is connected to, but that you don't want the system to keep up for your use case.

Applications build a NetworkRequest and pass it to one of the[ConnectivityManager](https://developer.android.com/reference/android/net/ConnectivityManager)methods above together with a[ConnectivityManager.NetworkCallback](https://developer.android.com/reference/android/net/ConnectivityManager.NetworkCallback)object. The callback will then start receiving method calls about networks that match the request.

Networks are brought up and/or matched according to the capabilities set in the builder. For example, a request with[NetworkCapabilities.NET_CAPABILITY_MMS](https://developer.android.com/reference/android/net/NetworkCapabilities#NET_CAPABILITY_MMS)lets the system match and/or bring up a network that is capable to send MMS. A request with[NetworkCapabilities.NET_CAPABILITY_NOT_METERED](https://developer.android.com/reference/android/net/NetworkCapabilities#NET_CAPABILITY_NOT_METERED)matches a network that doesn't charge the user for usage. See[NetworkCapabilities](https://developer.android.com/reference/android/net/NetworkCapabilities)for a list of capabilities and their description.

While all capabilities can be matched with the[ConnectivityManager.registerNetworkCallback](https://developer.android.com/reference/android/net/ConnectivityManager#registerNetworkCallback(android.net.NetworkRequest,%20android.app.PendingIntent))family of methods, not all capabilities can be used to request that the system brings up a network with[ConnectivityManager.requestNetwork](https://developer.android.com/reference/android/net/ConnectivityManager#requestNetwork(android.net.NetworkRequest,%20android.app.PendingIntent)). For example, an application cannot use[ConnectivityManager.requestNetwork](https://developer.android.com/reference/android/net/ConnectivityManager#requestNetwork(android.net.NetworkRequest,%20android.app.PendingIntent))to ask the system to bring up a network with[NetworkCapabilities.NET_CAPABILITY_CAPTIVE_PORTAL](https://developer.android.com/reference/android/net/NetworkCapabilities#NET_CAPABILITY_CAPTIVE_PORTAL), because the system won't know if a network has a captive portal before it connects to that network. Similarly, some capabilities may require a specific permission or privilege to be requested. Look up the specific capability and the[ConnectivityManager.requestNetwork](https://developer.android.com/reference/android/net/ConnectivityManager#requestNetwork(android.net.NetworkRequest,%20android.app.PendingIntent))method for limitations applicable to each capability.

Also, starting with[Build.VERSION_CODES.UPSIDE_DOWN_CAKE](https://developer.android.com/reference/android/os/Build.VERSION_CODES#UPSIDE_DOWN_CAKE), some capabilities require the application to self-certify by explicitly adding the[PackageManager.PROPERTY_SELF_CERTIFIED_NETWORK_CAPABILITIES](https://developer.android.com/reference/android/content/pm/PackageManager#PROPERTY_SELF_CERTIFIED_NETWORK_CAPABILITIES)property in the AndroidManifest.xml, which points to an XML resource file. In the XML resource file, the application declares what kind of network capabilities the application wants to have. Here is an example self-certification XML resource file :  

      <network-capabilities-declaration xmlns:android="http://schemas.android.com/apk/res/android">
         <uses-network-capability android:name="NET_CAPABILITY_PRIORITIZE_LATENCY"/>
         <uses-network-capability android:name="NET_CAPABILITY_PRIORITIZE_BANDWIDTH"/>
     </network-capabilities-declaration>
      
      
Look up the specific capability to learn whether its usage requires this self-certification.

### describeContents

Added in[API level 21](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[writeToParcel(android.os.Parcel, int)](https://developer.android.com/reference/android/os/Parcelable#writeToParcel(android.os.Parcel,%20int)), the return value of this method must include the[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR)bit.

|-------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `int` | a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either`0`or[CONTENTS_FILE_DESCRIPTOR](https://developer.android.com/reference/android/os/Parcelable#CONTENTS_FILE_DESCRIPTOR) <br /> |

### equals

Added in[API level 21](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.

|-----------|-------------------------------------------------------------------------------|
| `boolean` | `true`if this object is the same as the obj argument;`false`otherwise. <br /> |

### getCapabilities

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

```
public int[] getCapabilities ()
```

### hashCode

Added in[API level 21](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[HashMap](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[equals](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[equals](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.
