NetworkInfo

Kotlin |Java

public class NetworkInfo
extends Object implements Parcelable

java.lang.Object
↳	android.net.NetworkInfo

This class was deprecated in API level 29.
Callers should instead use the ConnectivityManager.NetworkCallback API to learn about connectivity changes, or switch to use ConnectivityManager.getNetworkCapabilities or ConnectivityManager.getLinkProperties to get information synchronously. Keep in mind that while callbacks are guaranteed to be called for every event in order, synchronous calls have no such constraints, and as such it is unadvisable to use the synchronous methods inside the callbacks as they will often not offer a view of networking that is consistent (that is: they may return a past or a future state with respect to the event being processed by the callback). Instead, callers are advised to only use the arguments of the callbacks, possibly memorizing the specific bits of information they need to keep from one callback to another.

Describes the status of a network interface.

Use ConnectivityManager.getActiveNetworkInfo() to get an instance that represents the current network connection.

Summary

Inherited constants

From interface android.os.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Fields
`public static final Creator<NetworkInfo>`	`CREATOR`

Public constructors
`NetworkInfo(int type, int subtype, String typeName, String subtypeName)` Create a new instance of NetworkInfo.

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`NetworkInfo.DetailedState`	`getDetailedState()` This method is deprecated. Apps should instead use the `ConnectivityManager.NetworkCallback` API to learn about connectivity changes. See `ConnectivityManager.registerDefaultNetworkCallback` and `ConnectivityManager.registerNetworkCallback`. These will give a more accurate picture of the connectivity state of the device and let apps react more easily and quickly to changes.
`String`	`getExtraInfo()` This method is deprecated. Use other services e.g. WifiManager to get additional information passed up from the lower networking layers.
`String`	`getReason()` This method was deprecated in API level 28. This method does not have a consistent contract that could make it useful to callers.
`NetworkInfo.State`	`getState()` This method was deprecated in API level 28. Apps should instead use the `ConnectivityManager.NetworkCallback` API to learn about connectivity changes. `ConnectivityManager.registerDefaultNetworkCallback` and `ConnectivityManager.registerNetworkCallback`. These will give a more accurate picture of the connectivity state of the device and let apps react more easily and quickly to changes.
`int`	`getSubtype()` This method was deprecated in API level 29. Use `TelephonyManager.getDataNetworkType()` instead.
`String`	`getSubtypeName()` This method was deprecated in API level 29. Use `TelephonyManager.getDataNetworkType()` instead.
`int`	`getType()` This method was deprecated in API level 28. Callers should switch to checking `NetworkCapabilities.hasTransport` instead with one of the NetworkCapabilities#TRANSPORT_* constants : `getType()` and `getTypeName()` cannot account for networks using multiple transports. Note that generally apps should not care about transport; `NetworkCapabilities.NET_CAPABILITY_NOT_METERED` and `NetworkCapabilities.getLinkDownstreamBandwidthKbps` are calls that apps concerned with meteredness or bandwidth should be looking at, as they offer this information with much better accuracy.
`String`	`getTypeName()` This method was deprecated in API level 28. Callers should switch to checking `NetworkCapabilities.hasTransport` instead with one of the NetworkCapabilities#TRANSPORT_* constants : `getType()` and `getTypeName()` cannot account for networks using multiple transports. Note that generally apps should not care about transport; `NetworkCapabilities.NET_CAPABILITY_NOT_METERED` and `NetworkCapabilities.getLinkDownstreamBandwidthKbps` are calls that apps concerned with meteredness or bandwidth should be looking at, as they offer this information with much better accuracy.
`boolean`	`isAvailable()` This method was deprecated in API level 28. Apps should instead use the `ConnectivityManager.NetworkCallback` API to learn about connectivity changes. `ConnectivityManager.registerDefaultNetworkCallback` and `ConnectivityManager.registerNetworkCallback`. These will give a more accurate picture of the connectivity state of the device and let apps react more easily and quickly to changes.
`boolean`	`isConnected()` This method is deprecated. Apps should instead use the `ConnectivityManager.NetworkCallback` API to learn about connectivity changes. See `ConnectivityManager.registerDefaultNetworkCallback` and `ConnectivityManager.registerNetworkCallback`. These will give a more accurate picture of the connectivity state of the device and let apps react more easily and quickly to changes.
`boolean`	`isConnectedOrConnecting()` This method was deprecated in API level 28. Apps should instead use the `ConnectivityManager.NetworkCallback` API to learn about connectivity changes. `ConnectivityManager.registerDefaultNetworkCallback` and `ConnectivityManager.registerNetworkCallback`. These will give a more accurate picture of the connectivity state of the device and let apps react more easily and quickly to changes.
`boolean`	`isFailover()` This method was deprecated in API level 28. This field is not populated in recent Android releases, and does not make a lot of sense in a multi-network world.
`boolean`	`isRoaming()` This method was deprecated in API level 28. Callers should switch to checking `NetworkCapabilities.NET_CAPABILITY_NOT_ROAMING` instead, since that handles more complex situations, such as VPNs.
`void`	`setDetailedState(NetworkInfo.DetailedState detailedState, String reason, String extraInfo)` This method was deprecated in API level 29. Use `NetworkCapabilities` instead.
`String`	`toString()` Returns a string representation of the object.
`void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Indicates whether network connectivity is possible. A network is unavailable when a persistent or semi-persistent condition prevents the possibility of connecting to that network. Examples include

The device is out of the coverage area for any network of this type.
The device is on a network other than the home network (i.e., roaming), and data roaming has been disabled.
The device's radio is turned off, e.g., because airplane mode is enabled.

`boolean`	`true` if network connectivity exists or is in the process of being established, `false` otherwise.

isFailover

Deprecated in API level 28

 public boolean isFailover ()

This method was deprecated in API level 28.
This field is not populated in recent Android releases, and does not make a lot of sense in a multi-network world.

Indicates whether the current attempt to connect to the network resulted from the ConnectivityManager trying to fail over to this network following a disconnect from another network.

This method was deprecated in API level 28.
Callers should switch to checking NetworkCapabilities.NET_CAPABILITY_NOT_ROAMING instead, since that handles more complex situations, such as VPNs.

Indicates whether the device is currently roaming on this network. When true, it suggests that use of data on this network may incur extra costs.
