NetworkCapabilities

---

Kotlin |Java

class NetworkCapabilities : Parcelable

kotlin.Any
↳	android.net.NetworkCapabilities

Representation of the capabilities of an active network.

@see hasCapability(int). See the list of capabilities and each capability for a description of what it means.

Some prime examples include NET_CAPABILITY_MMS, which means that the network is capable of sending MMS. A network without this capability is not capable of sending MMS.

The NET_CAPABILITY_INTERNET capability means that the network is configured to reach the general Internet. It may or may not actually provide connectivity ; the NET_CAPABILITY_VALIDATED bit indicates that the system found actual connectivity to the general Internet the last time it checked. Apps interested in actual connectivity should usually look at both these capabilities.

The NET_CAPABILITY_NOT_METERED capability is set for networks that do not bill the user for consumption of bytes. Applications are encouraged to consult this to determine appropriate usage, and to limit usage of metered network where possible, including deferring big downloads until such a time that an unmetered network is connected. Also see android.app.job.JobScheduler to help with scheduling such downloads, in particular android.app.job.JobInfo.Builder#setRequiredNetwork(NetworkRequest).

NetworkCapabilities contain a number of other capabilities that represent what modern networks can and can't do. Look up the individual capabilities in this class to learn about each of them.

NetworkCapabilities typically represent attributes that can apply to any network. The attributes that apply only to specific transports like cellular or Wi-Fi can be found in the specifier (for requestable attributes) or in the transport info (for non-requestable ones). See getNetworkSpecifier and getTransportInfo. An app would downcast these to the specific class for the transport they need if they are interested in transport-specific attributes. Also see android.net.wifi.WifiNetworkSpecifier or android.net.wifi.WifiInfo for some examples of each of these.

NetworkCapabilities also contains other attributes like the estimated upstream and downstream bandwidth and the specific transport of that network (e.g. TRANSPORT_CELLULAR). Generally, apps should normally have little reason to check for the type of transport ; for example, to query whether a network costs money to the user, do not look at the transport, but instead look at the absence or presence of NET_CAPABILITY_NOT_METERED which will correctly account for metered Wi-Fis and free of charge cell connections.

The system communicates with apps about connected networks and uses NetworkCapabilities to express these capabilities about these networks. Apps should register callbacks with the android.net.ConnectivityManager#requestNetwork or android.net.ConnectivityManager#registerNetworkCallback family of methods to learn about the capabilities of a network on a continuous basis and be able to react to changes to capabilities. For quick debugging Android also provides ConnectivityManager.getNetworkCapabilities(Network), but the dynamic nature of networking makes this ill-suited to production code since capabilities obtained in this way can go stale immediately.

Also see NetworkRequest which uses the same capabilities together with android.net.ConnectivityManager#requestNetwork for how to request the system brings up the kind of network your application needs.

• USB tethering or Wi-Fi hotspot networks to which the device is sharing its Internet connectivity.
• Thread networks where the current device is the Thread Border Router.
• Wi-Fi P2P networks where the current device is the Group Owner.

Networks used to obtain Internet access are never local networks. Apps that target an SDK before Build.VERSION_CODES.VANILLA_ICE_CREAM will not see networks with this capability unless they explicitly set the NET_CAPABILITY_LOCAL_NETWORK in their NetworkRequests.

Added in API level Baklava

static val NET_CAPABILITY_NOT_BANDWIDTH_CONSTRAINED: Int

Indicates that this is not a bandwidth-constrained network. Starting from Build.VERSION_CODES.VANILLA_ICE_CREAM, this capability is by default set in NetworkRequests and true for most networks. If a network lacks this capability, it is bandwidth-constrained. Bandwidth constrained networks cannot support high-bandwidth data transfers and applications that request and use them must ensure that they limit bandwidth usage to below the values returned by getLinkDownstreamBandwidthKbps() and getLinkUpstreamBandwidthKbps() and limit the frequency of their network usage. If applications perform high-bandwidth data transfers on constrained networks or perform network access too frequently, the system may block the app's access to the network. The system may take other measures to reduce network usage on constrained networks, such as disabling network access to apps that are not in the foreground.

Value: 37

NET_CAPABILITY_NOT_CONGESTED

Added in API level 28

static val NET_CAPABILITY_NOT_CONGESTED: Int

Indicates that this network is not congested.

Value: 20

NET_CAPABILITY_NOT_METERED

Added in API level 21

static val NET_CAPABILITY_NOT_METERED: Int

Indicates that this network is unmetered.

Value: 11

NET_CAPABILITY_NOT_RESTRICTED

Added in API level 21

static val NET_CAPABILITY_NOT_RESTRICTED: Int

Indicates that this network is available for general use. If this is not set applications should not attempt to communicate on this network. Note that this is simply informative and not enforcement - enforcement is handled via other means. Set by default.

Value: 13

NET_CAPABILITY_NOT_ROAMING

Added in API level 28

static val NET_CAPABILITY_NOT_ROAMING: Int

Indicates that this network is not roaming.

Value: 18

NET_CAPABILITY_NOT_SUSPENDED

Added in API level 28

static val NET_CAPABILITY_NOT_SUSPENDED: Int

Indicates that this network is not currently suspended.

When a network is suspended, the network's IP addresses and any connections established on the network remain valid, but the network is temporarily unable to transfer data. This can happen, for example, if a cellular network experiences a temporary loss of signal, such as when driving through a tunnel, etc. A network with this capability is not suspended, so is expected to be able to transfer data.

Value: 21

NET_CAPABILITY_NOT_VPN

Added in API level 21

static val NET_CAPABILITY_NOT_VPN: Int

Indicates that this network is not a VPN. This capability is set by default and should be explicitly cleared for VPN networks.

Value: 15

NET_CAPABILITY_TEMPORARILY_NOT_METERED

Added in API level 30

static val NET_CAPABILITY_TEMPORARILY_NOT_METERED: Int

Indicates that this network is temporarily unmetered.

This capability will be set for networks that are generally metered, but are currently unmetered, e.g., because the user is in a particular area. This capability can be changed at any time. When it is removed, applications are responsible for stopping any data transfer that should not occur on a metered network. Note that most apps should use NET_CAPABILITY_NOT_METERED instead. For more information, see https://developer.android.com/about/versions/11/features/5g#meteredness.

Value: 25

NetworkCapabilities(nc: NetworkCapabilities!)

Public methods

describeContents

Added in API level 21

fun describeContents(): Int

Return
Int	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either 0 or android.os.Parcelable#CONTENTS_FILE_DESCRIPTOR

equals

Added in API level 21

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	This value may be null.

Return
Boolean	true if this object is the same as the obj argument; false otherwise.

getNetworkSpecifier

Added in API level 30

fun getNetworkSpecifier(): NetworkSpecifier?

Gets the optional bearer specific network specifier. May be null if not set.

Return
NetworkSpecifier?	The optional NetworkSpecifier specifying the bearer specific network specifier or null.

getOwnerUid

Added in API level 30

fun getOwnerUid(): Int

Retrieves the UID of the app that owns this network.

For user privacy reasons, this field will only be populated if the following conditions are met:

The caller is the network owner, AND one of the following sets of requirements is met:

1. The described Network is a VPN

OR:

1. The calling app is the network owner
2. The calling app has the ACCESS_FINE_LOCATION permission granted
3. The user's location toggle is on

Instances of NetworkCapabilities sent to apps without the appropriate permissions will have this field cleared out.

This field will only be populated for VPN and wifi network suggestor apps (i.e using WifiNetworkSuggestion), and only for the network they own. In the case of wifi network suggestors apps, this field is also location sensitive, so the app needs to hold android.Manifest.permission#ACCESS_FINE_LOCATION permission. If the app targets SDK version greater than or equal to Build.VERSION_CODES.S, then they also need to use NetworkCallback.FLAG_INCLUDE_LOCATION_INFO to get the info in their callback. If the apps targets SDK version equal to {Build.VERSION_CODES.R, this field will always be included. The app will be blamed for location access if this field is included.

getSignalStrength

Added in API level 29

fun getSignalStrength(): Int

Retrieves the signal strength.

Return
Int	The bearer-specific signal strength.

getSubscriptionIds

Added in API level 35

Return
MutableSet<Int!>	This value cannot be null.

getTransportInfo

Added in API level 29

fun getTransportInfo(): TransportInfo?

Returns a transport-specific information container. The application may cast this container to a concrete sub-class based on its knowledge of the network request. The application should be able to deal with a null return value or an invalid case, e.g. use instanceof operator to verify expected type.

Return
TransportInfo?	A concrete implementation of the TransportInfo class or null if not available for the network.
