Method Detail

disableSoftAP

public void disableSoftAP()
                   throws IOException

Disables the Software enabled Access Point (SoftAP). This method has no effect if the SoftAP is not started.

Throws:

IOException - if an I/O error occurs

enableSoftAP

public void enableSoftAP(SoftAPConfiguration configuration)
                  throws IOException

Enables the SoftAP with a given configuration.

Parameters:

configuration - SoftAP configuration.

Throws:

IOException - if SoftAP mode is not supported, an access point is currently joined and the platform does support simultaneous mode (leave() must be called before this method) or an I/O error occurs.

getCapability

public WifiCapability getCapability()
                             throws IOException

Gets the Wi-Fi capability of the platform.

Returns:

Wi-Fi capability.

Throws:

IOException - If an I/O error occurs.

getInstance

public static WifiManager getInstance()

Returns the WifiManager instance.

Returns:

WifiManager instance.

getJoined

@Nullable
public AccessPoint getJoined()
                                throws IOException

Gets the currently joined Wi-Fi access point.

Returns:

currently joined Wi-Fi access point or null if no Wi-Fi access point has been joined yet.

Throws:

IOException - If an I/O error occurs.

isSoftAPEnabled

public boolean isSoftAPEnabled()
                        throws IOException

Tells whether if SoftAP is currently enabled.

Returns:

true if enabled, false otherwise.

Throws:

IOException - If an I/O error occurs.

join

public void join(AccessPoint accessPoint,
                 String passphrase,
                 SecurityMode securityMode)
          throws IOException

Joins a Wi-Fi network using a Wi-Fi access point, a passphrase and a security mode.

Parameters:

accessPoint - Wi-Fi access point.

passphrase - Wi-Fi access point passphrase. The passphrase must be a sequence of between 8 and 64 ASCII-encoded characters.

securityMode - Wi-Fi access point security mode.

Throws:

IOException - if client mode is not supported, the SoftAP is currently enabled and the platform does support simultaneous mode ( disableSoftAP() must be called before this method), or an I/O error occurs.

IllegalArgumentException - if the accessPoint or the passphrase is null.

join

public void join(String SSID,
                 String passphrase)
          throws IOException

Joins a Wi-Fi network using a SSID and a passphrase.

Parameters:

SSID - Wi-Fi access point Service Set Identifier (SSID).

passphrase - Wi-Fi access point passphrase. The passphrase must be a sequence of between 8 and 64 ASCII-encoded characters.

Throws:

IOException - if client mode is not supported, the SoftAP is currently enabled and the platform does support simultaneous mode ( disableSoftAP() must be called before this method), or an I/O error occurs.

IllegalArgumentException - if the SSID or the passphrase is null.

join

public void join(String SSID,
                 String passphrase,
                 SecurityMode securityMode)
          throws IOException

Joins a wireless network using an SSID and a passphrase.

Parameters:

SSID - Wi-Fi access point Service Set Identifier (SSID).

passphrase - Wi-Fi access point passphrase. The passphrase must be a sequence of between 8 and 64 ASCII-encoded characters.

securityMode - Wi-Fi access point security mode.

Throws:

IOException - if client mode is not supported, the SoftAP is currently enabled and the platform does support simultaneous mode ( disableSoftAP() must be called before this method), or an I/O error occurs.

IllegalArgumentException - if the SSID or the passphrase is null.

leave

public void leave()
           throws IOException

Leaves the currently joined Wi-Fi access point. If no Wi-Fi access point has been joined yet, this method has no effect.

Throws:

IOException - If an I/O error occurs.

scan

public AccessPoint[] scan()
                   throws IOException

Performs an active scan of available Wi-Fi access points. This is equivalent to scan(true).

Returns:

the list of available Wi-Fi access points or an empty list if there is no available Wi-Fi access point.

Throws:

IOException - if the underlying Wi-Fi network interface is currently stopped, scanning is not possible at the moment, or an I/O error occurs.

scan

public AccessPoint[] scan(boolean active)
                   throws IOException

Performs a scan of available access points.

Parameters:

active - true for an active scan, false for a passive scan.

Returns:

the list of available access points or an empty list if there is no available Wi-Fi access point.

Throws:

IOException - if the underlying network interface is currently stopped, scanning is not possible at the moment, or an I/O error occurs.
