• Enum Constant Detail

  • DISCONNECTED

    public static 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.

  • INTERFACE_DISABLED

    public static final SupplicantState INTERFACE_DISABLED

    Interface is disabled

    This state is entered if the network interface is disabled. wpa_supplicant refuses any new operations that would use the radio until the interface has been enabled.

  • INACTIVE

    public static final SupplicantState INACTIVE

    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.

  • SCANNING

    public static final SupplicantState SCANNING

    Scanning for a network.

    This state is entered when wpa_supplicant starts scanning for a network.

  • AUTHENTICATING

    public static final SupplicantState AUTHENTICATING

    Trying to authenticate with a BSS/SSID

    This state is entered when wpa_supplicant has found a suitable BSS to authenticate with and the driver is configured to try to authenticate with this BSS.

  • ASSOCIATING

    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.

  • ASSOCIATED

    public static final 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.

  • FOUR_WAY_HANDSHAKE

    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.

  • GROUP_HANDSHAKE

    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).

  • COMPLETED

    public static final SupplicantState COMPLETED

    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.

  • DORMANT

    public static final SupplicantState DORMANT

    An Android-added state that is reported when a client issues an explicit DISCONNECT command. In such a case, the supplicant is not only dissociated from the current access point (as for the DISCONNECTED state above), but it also does not attempt to connect to any access point until a RECONNECT or REASSOCIATE command is issued by the client.

  • UNINITIALIZED

    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.

  • INVALID

    public static final SupplicantState INVALID

    A pseudo-state that should normally never be seen.

• Field Detail

  • CREATOR

    public static final Parcelable.Creator<SupplicantState> CREATOR

    Implement the Parcelable interface

• Method Detail

  • values

    public static SupplicantState[] values()

    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

    for (SupplicantState c : SupplicantState.values())
        System.out.println(c);
    

    Returns:

    an array containing the constants of this enum type, in the order they are declared

  • valueOf

    public static SupplicantState valueOf(String name)

    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

    Parameters:

    name - the name of the enum constant to be returned.

    Returns:

    the enum constant with the specified name

    Throws:

    IllegalArgumentException - if this enum type has no constant with the specified name

    NullPointerException - if the argument is null

  • isValidState

    public static boolean isValidState(SupplicantState state)

    Returns true if the supplicant state is valid and false otherwise.

    Parameters:

    state - The supplicant state

    Returns:

    true if the supplicant state is valid and false otherwise.

  • isHandshakeState

    public static boolean isHandshakeState(SupplicantState state)

    Supplicant associating or authenticating is considered a handshake state

  • describeContents

    public int describeContents()

    Implement the Parcelable interface

    Specified by:

    describeContents in interface Parcelable

    Returns:

    a bitmask indicating the set of special object types marshalled by the Parcelable.

  • writeToParcel

    public void writeToParcel(Parcel dest,
                     int flags)

    Implement the Parcelable interface

    Specified by:

    writeToParcel in interface Parcelable

    Parameters:

    dest - The Parcel in which the object should be written.

    flags - Additional flags about how the object should be written. May be 0 or Parcelable.PARCELABLE_WRITE_RETURN_VALUE.
