deviceAddress
public String deviceAddress
The device MAC address uniquely identifies a Wi-Fi p2p device
deviceName
public String deviceName
The device name is a user friendly string to identify a Wi-Fi p2p device
primaryDeviceType
public String primaryDeviceType
Primary device type identifies the type of device. For example, an application could filter the devices discovered to only display printers if the purpose is to enable a printing action from the user. See the Wi-Fi Direct technical specification for the full list of standard device types supported.
secondaryDeviceType
public String secondaryDeviceType
Secondary device type is an optional attribute that can be provided by a device in addition to the primary device type.

Public methods
describeContents
public int describeContents ()
Implement the Parcelable interface
Returns | |
---|---|
int |
a bitmask indicating the set of special object types marshaled
by this Parcelable object instance.
Value is either 0 or CONTENTS_FILE_DESCRIPTOR |
equals
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 returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
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 |
Object : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if this object is the same as the obj
argument; false otherwise. |
getIpAddress
public InetAddress getIpAddress ()
Get the IP address of the connected client device.
The application should listen to WifiP2pManager#WIFI_P2P_CONNECTION_CHANGED_ACTION
broadcast to obtain the IP address of the connected client. When system assigns the IP
address, the connected P2P device information (WifiP2pGroup#getClientList()
) in the
group is updated with the IP address and broadcast the group information using
WifiP2pManager#EXTRA_WIFI_P2P_GROUP
extra of the
WifiP2pManager#WIFI_P2P_CONNECTION_CHANGED_ACTION
broadcast intent.
Alternatively, the application can request for the group details with
WifiP2pManager#requestGroupInfo
and use (WifiP2pGroup#getClientList()
) to
obtain the connected client details.
Returns | |
---|---|
InetAddress |
the IP address if the device is a part of the group; otherwise null. |
getVendorElements
public List<ScanResult.InformationElement> getVendorElements ()
Get the vendor-specific information elements received as part of the discovery of the peer device.
Returns | |
---|---|
List<ScanResult.InformationElement> |
the list of vendor-specific information elements
The information element format is defined in the IEEE 802.11-2016 spec
Table 9-77.
This value cannot be null . |
getWfdInfo
public WifiP2pWfdInfo getWfdInfo ()
The Wifi Display information for this device, or null if unavailable.
Returns | |
---|---|
WifiP2pWfdInfo |
hashCode
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
.
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 inequals
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
method, then calling thehashCode
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
method, then calling thehashCode
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.
Returns | |
---|---|
int |
a hash code value for this object. |
isGroupOwner
public boolean isGroupOwner ()
Returns true if the device is a group owner
Returns | |
---|---|
boolean |
isServiceDiscoveryCapable
public boolean isServiceDiscoveryCapable ()
Returns true if the device is capable of service discovery
Returns | |
---|---|
boolean |
toString
public String toString ()
Returns a string representation of the object.
Returns | |
---|---|
String |
a string representation of the object. |
update
public void update (WifiP2pDevice device)
Update this device's details using another WifiP2pDevice
instance.
This will throw an exception if the device address does not match.
Parameters | |
---|---|
device |
WifiP2pDevice : another instance of WifiP2pDevice used to update this instance.
This value cannot be null . |
Throws | |
---|---|
IllegalArgumentException |
if the device is null or the device address does not match |
wpsDisplaySupported
public boolean wpsDisplaySupported ()
Returns true if WPS display configuration is supported
Returns | |
---|---|

writeToParcel
public void writeToParcel (Parcel dest, int flags)
Implement the Parcelable interface
Parameters | |
---|---|
dest |
Parcel : The Parcel in which the object should be written.
This value cannot be null . |
flags |
int : Additional flags about how the object should be written.
May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE .
Value is either 0 or a combination of Parcelable.PARCELABLE_WRITE_RETURN_VALUE , and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES |
