1.目的安卓代码连接WiFi（android 4.0 ，AS4.0）
2.代码：
//创建WiFi连接信息
public WifiConfiguration createWifiInfo(String SSID, String Password, int Type) { WifiConfiguration configuration = new WifiConfiguration(); configuration.allowedAuthAlgorithms.clear(); configuration.allowedGroupCiphers.clear(); configuration.allowedKeyManagement.clear(); configuration.allowedPairwiseCiphers.clear(); configuration.allowedProtocols.clear(); configuration.SSID = "\"" + SSID + "\""; WifiConfiguration tempConfig = this.isExsits(SSID); if(tempConfig != null) { //mWifiManager.removeNetwork(tempConfig.networkId); } switch (Type) { case 1://不加密 configuration.wepKeys[0] = ""; configuration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); configuration.wepTxKeyIndex = 0; configuration.priority= 20000; break; case 2://wep加密 configuration.hiddenSSID = true; configuration.wepKeys[0] = "\"" + Password +"\""; configuration.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED); configuration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); configuration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); configuration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40); configuration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104); configuration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); break; case 3: //wpa加密 configuration.preSharedKey = "\"" + Password + "\""; configuration.hiddenSSID = true; configuration.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN); configuration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); configuration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); configuration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK); configuration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP); configuration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP); configuration.status = WifiConfiguration.Status.ENABLED; break; } return configuration; }
//初始化WiFi WifiManager mWifiManager = (WifiManager) getApplicationContext().getSystemService(WIFI_SERVICE); //初始化类 WifiConnectUtil wifiUtil = new WifiConnectUtil(mWifiManager); //连接调用连接类 int networkId = mWifiManager.addNetwork(wifiUtil.createWifiInfo(settingCardInfo.SSID,settingCardInfo.SSIDPassword,3)); //连接WiFi mWifiManager.enableNetwork(networkId, true);
mWifiManager.saveConfiguration();//保存连接信息
