enum
android.net.wifi.SupplicantState
From defs.h
in wpa_supplicant
.
These enumeration values are used to indicate the current wpa_supplicant
state. This is more fine-grained than most users will be interested in.
In general, it is better to use
NetworkInfo.State.
Note, the order of these enum constants must match the numerical values of the
state constants in
defs.h
in
wpa_supplicant
.

SupplicantState
ASSOCIATED
Association completed.
This state is entered when the driver reports that association has
been successfully completed with an AP. If IEEE 802.1X is used
(with or without WPA/WPA2), wpa_supplicant remains in this state
until the IEEE 802.1X/EAPOL authentication has been completed.
public
static
final
SupplicantState
ASSOCIATING
Trying to associate with a BSS/SSID.
This state is entered when wpa_supplicant has found a suitable BSS
to associate with and the driver is configured to try to associate
with this BSS in ap_scan=1 mode. When using ap_scan=2 mode, this
state is entered when the driver is configured to try to associate
with a network using the configured SSID and security policy.
All authentication completed.
This state is entered when the full authentication process is
completed. In case of WPA2, this happens when the 4-Way Handshake is
successfully completed. With WPA, this state is entered after the
Group Key Handshake; with IEEE 802.1X (non-WPA) connection is
completed after dynamic keys are received (or if not used, after
the EAP authentication has been completed). With static WEP keys and
plaintext connections, this state is entered when an association
has been completed.
This state indicates that the supplicant has completed its
processing for the association phase and that data connection is
fully configured. Note, however, that there may not be any IP
address associated with the connection yet. Typically, a DHCP
request needs to be sent at this point to obtain an address.

final
SupplicantState
DISCONNECTED
This state indicates that client is not associated, but is likely to
start looking for an access point. This state is entered when a
connection is lost.
public
static
final
SupplicantState
FOUR_WAY_HANDSHAKE
WPA 4-Way Key Handshake in progress.
This state is entered when WPA/WPA2 4-Way Handshake is started. In
case of WPA-PSK, this happens when receiving the first EAPOL-Key
frame after association. In case of WPA-EAP, this state is entered
when the IEEE 802.1X/EAPOL authentication has been completed.
public
static
final
SupplicantState
GROUP_HANDSHAKE
WPA Group Key Handshake in progress.
This state is entered when 4-Way Key Handshake has been completed
(i.e., when the supplicant sends out message 4/4) and when Group
Key rekeying is started by the AP (i.e., when supplicant receives
message 1/2).
Inactive state (wpa_supplicant disabled).
This state is entered if there are no enabled networks in the
configuration. wpa_supplicant is not trying to associate with a new
network and external interaction (e.g., ctrl_iface call to add or
enable a network) is needed to start association.
A pseudo-state that should normally never be seen.
Scanning for a network.
This state is entered when wpa_supplicant starts scanning for a
network.
public
static
final
SupplicantState
UNINITIALIZED
No connection to wpa_supplicant.
This is an additional pseudo-state to handle the case where
wpa_supplicant is not running and/or we have not been able
to establish a connection to it.
