String LINK_SPEED_UNITS
Link speed in Mbps
Constant Value: "Mbps"
String getBSSID ()
Return the basic service set identifier (BSSID) of the current access point.
The BSSID may be null if there is no network currently connected.
| Returns | |
|---|---|
String |
the BSSID, in the form of a six-byte MAC address: XX:XX:XX:XX:XX:XX
|
NetworkInfo.DetailedState getDetailedStateOf (SupplicantState suppState)
Map a supplicant state into a fine-grained network connectivity state.
| Parameters | |
|---|---|
suppState |
SupplicantState:
the supplicant state |
| Returns | |
|---|---|
NetworkInfo.DetailedState |
the corresponding NetworkInfo.DetailedState
|
int getFrequency ()
Returns the current frequency in FREQUENCY_UNITS.
| Returns | |
|---|---|
int |
the frequency. |
See also:
boolean getHiddenSSID ()
| Returns | |
|---|---|
boolean |
true if this network does not broadcast its SSID, so an
SSID-specific probe request must be used for scans.
|
int getLinkSpeed ()
Returns the current link speed in LINK_SPEED_UNITS.
| Returns | |
|---|---|
int |
the link speed. |
See also:
int getNetworkId ()
Each configured network has a unique small integer ID, used to identify the network when performing operations on the supplicant. This method returns the ID for the currently connected network.
| Returns | |
|---|---|
int |
the network ID, or -1 if there is no currently connected network |
int getRssi ()
Returns the received signal strength indicator of the current 802.11 network, in dBm.
Use calculateSignalLevel(int, int) to convert this number into
an absolute signal level which can be displayed to a user.
| Returns | |
|---|---|
int |
the RSSI. |
String getSSID ()
Returns the service set identifier (SSID) of the current 802.11 network. If the SSID can be decoded as UTF-8, it will be returned surrounded by double quotation marks. Otherwise, it is returned as a string of hex digits. The SSID may be <unknown ssid> if there is no network currently connected.
| Returns | |
|---|---|
String |
the SSID |
SupplicantState getSupplicantState ()
Return the detailed state of the supplicant's negotiation with an
access point, in the form of a SupplicantState object.
| Returns | |
|---|---|
SupplicantState |
the current SupplicantState
|
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. |
