连接 WPA2 加密

此示例使用 WPA2 加密连接到 Wi-Fi 接入点。

public boolean ConnectToNetworkWPA(String networkSSID, String password) {
  try {
    WifiConfiguration conf = new WifiConfiguration();
    conf.SSID = "\"" + networkSSID + "\"";   // Please note the quotes. String should contain SSID in quotes

    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 Connection success, return true
    return true;
  } catch (Exception ex) {
    System.out.println(Arrays.toString(ex.getStackTrace()));
    return false;
  }
}
