android连接程序,WiFi连接Android应用程序

好问题。只需尝试连接到已定义的AP并验证结果：

WifiConfiguration wc = new WifiConfiguration();

...

// If password is empty, it should be left untouched

if (!TextUtils.isEmpty(pswd)) {

if (pswd.length() == 64) {

// Goes unquoted as hex

wc.preSharedKey = pswd;

} else {

// Goes quoted as ASCII

wc.preSharedKey = TextUtil.convertToQuotedString(pswd);

}

}

int res = -1;

res = m_WifiManager.addNetwork(wc);

boolean b = m_WifiManager.enableNetwork(res, true);

if(b == true){

fixSupplicant();

m_WifiManager.saveConfiguration();

//success

}

else{

//failed

....

private void fixSupplicant() {

final SupplicantState state = m_WifiManager.getConnectionInfo().getSupplicantState();

boolean isReconnectDone = false;

if ((state == SupplicantState.SCANNING)

|| (state == SupplicantState.DISCONNECTED)

|| (state == SupplicantState.DORMANT)) {

isReconnectDone = m_WifiManager.reconnect();;

}

}
