public class Network
extends Object
implements Parcelable
java.lang.Object | |
↳ | android.net.Network |
Identifies a Network
. This is supplied to applications via ConnectivityManager.NetworkCallback
in response to the active requestNetwork(NetworkRequest, PendingIntent)
or passive registerNetworkCallback(NetworkRequest, PendingIntent)
calls. It is used to direct traffic to the given Network
, either on a Socket
basis through a targeted SocketFactory
or process-wide via bindProcessToNetwork(Network)
.

void bindSocket (DatagramSocket socket)
Binds the specified DatagramSocket
to this Network
. All data traffic on the socket will be sent on this Network
, irrespective of any process-wide network binding set by bindProcessToNetwork(Network)
. The socket must not be connected.
Parameters | |
---|---|
socket |
DatagramSocket
|
Throws | |
---|---|
IOException |
void bindSocket (Socket socket)
Binds the specified Socket
to this Network
. All data traffic on the socket will be sent on this Network
, irrespective of any process-wide network binding set by bindProcessToNetwork(Network)
. The socket must not be connected.
Parameters | |
---|---|
socket |
Socket
|
Throws | |
---|---|
IOException |
void bindSocket (FileDescriptor fd)
Binds the specified FileDescriptor
to this Network
. All data traffic on the socket represented by this file descriptor will be sent on this Network
, irrespective of any process-wide network binding set by bindProcessToNetwork(Network)
. The socket must not be connected.
Parameters | |
---|---|
fd |
FileDescriptor
|
Throws | |
---|---|
IOException |
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(Parcel, int)
, the return value of this method must include the CONTENTS_FILE_DESCRIPTOR
bit.
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled by this Parcelable object instance. |
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:
x
, x.equals(x)
should return true
. x
and y
, x.equals(y)
should return true
if and only if y.equals(x)
returns true
. x
, y
, and z
, if x.equals(y)
returns true
and y.equals(z)
returns true
, then x.equals(z)
should return true
. 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. x
, x.equals(null)
should return false
. The equals
method for class Object
implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x
and y
, this method returns true
if and only if x
and y
refer to the same object (x == y
has the value true
).
Note that it is generally necessary to override the hashCode
method whenever this method is overridden, so as to maintain the general contract for the hashCode
method, which states that equal objects must have equal hash codes.
Parameters | |
---|---|
obj |
Object : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if this object is the same as the obj argument; false otherwise. |
InetAddress[] getAllByName (String host)
Operates the same as InetAddress.getAllByName
except that host resolution is done on this network.
Parameters | |
---|---|
host |
String : the hostname or literal IP string to be resolved. |
Returns | |
---|---|
InetAddress[] |
the array of addresses associated with the specified host. |
Throws | |
---|---|
UnknownHostException |
if the address lookup fails. |
InetAddress getByName (String host)
Operates the same as InetAddress.getByName
except that host resolution is done on this network.
Parameters | |
---|---|
host |
String : the hostName to be resolved to an address or null . |
Returns | |
---|---|
InetAddress |
the InetAddress instance representing the host. |
Throws | |
---|---|
UnknownHostException |
if the address lookup fails. |
long getNetworkHandle ()
Returns a handle representing this Network
, for use with the NDK API.
Returns | |
---|---|
long |
SocketFactory getSocketFactory ()
Returns a SocketFactory
bound to this network. Any Socket
created by this factory will have its traffic sent over this Network
. Note that if this Network
ever disconnects, this factory and any Socket
it produced in the past or future will cease to work.
Returns | |
---|---|
SocketFactory |
a SocketFactory which produces Socket instances bound to this Network . |
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
.
The general contract of hashCode
is:
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. equals(Object)
method, then calling the hashCode
method on each of the two objects must produce the same integer result. 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. As much as is reasonably practical, the hashCode method defined by class Object
does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
Returns | |
---|---|
int |
a hash code value for this object. |
URLConnection openConnection (URL url)
Opens the specified URL
on this Network
, such that all traffic will be sent on this Network. The URL protocol must be HTTP
or HTTPS
.
Parameters | |
---|---|
url |
URL
|
Returns | |
---|---|
URLConnection |
a URLConnection to the resource referred to by this URL. |
Throws | |
---|---|
MalformedURLException |
if the URL protocol is not HTTP or HTTPS. |
IOException |
if an error occurs while opening the connection. |
See also:
URLConnection openConnection (URL url, Proxy proxy)
Opens the specified URL
on this Network
, such that all traffic will be sent on this Network. The URL protocol must be HTTP
or HTTPS
.
Parameters | |
---|---|
url |
URL
|
proxy |
Proxy : the proxy through which the connection will be established. |
Returns | |
---|---|
URLConnection |
a URLConnection to the resource referred to by this URL. |
Throws | |
---|---|
MalformedURLException |
if the URL protocol is not HTTP or HTTPS. |
IllegalArgumentException |
if the argument proxy is null. |
IOException |
if an error occurs while opening the connection. |

String toString ()
Returns a string representation of the object. In general, the toString
method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
The toString
method for class Object
returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@
', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
Returns | |
---|---|
String |
a string representation of the object. |
void writeToParcel (Parcel dest, int flags)
Flatten this object in to a Parcel.
Parameters | |
---|---|
dest |
Parcel : The Parcel in which the object should be written. |
flags |
int : Additional flags about how the object should be written. May be 0 or PARCELABLE_WRITE_RETURN_VALUE . |
