Android 使用WPA2加密连接
示例
本示例连接到具有WPA2加密的Wi-Fi接入点。
public boolean ConnectToNetworkWPA(String networkSSID, String password) {
try {
WifiConfiguration conf = new WifiConfiguration();
conf.SSID= "\"" + networkSSID + "\""; //请注意引号。字符串应在引号中包含SSID
conf.preSharedKey= "\"" + password + "\"";
conf.status= WifiConfiguration.Status.ENABLED;
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
Log.d("connecting",conf.SSID+ " " + conf.preSharedKey);
WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.addNetwork(conf);
Log.d("after connecting",conf.SSID+ " " + conf.preSharedKey);
List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
for( WifiConfiguration i : list ) {
if(i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) {
wifiManager.disconnect();
wifiManager.enableNetwork(i.networkId, true);
wifiManager.reconnect();
Log.d("re connecting",i.SSID+ " " + conf.preSharedKey);
break;
}
}
//WiFi连接成功，返回true
return true;
} catch (Exception ex) {
System.out.println(Arrays.toString(ex.getStackTrace()));
return false;
}
}
