我正在尝试为 Android 创建一个 WifiConfiguration。可以设置所有其他属性。但是如果我尝试设置 SSID 或 BSSID，我会遇到分段错误 (11)，并且应用程序和 Delphi 只是挂起。

var
  WIFIConfig: JWifiConfiguration;
begin
  WIFIConfig :=  TJWifiConfiguration.JavaClass.init; 
  WIFIConfig.hiddenSSID := false;                         -> works
  WIFIConfig.SSID := StringtoJString('"YOUR_WLAN_SSID"'); -> App just hangs
end;

http://developer.android.com/reference/android/net/wifi/WifiConfiguration.html

   JWifiConfigurationClass = interface(JObjectClass)
    ['{F69F53BC-BC63-436A-8DA9-57389B30CAA8}']
    function init: JWifiConfiguration; cdecl; overload;

  end;

  [JavaSignature('android/net/wifi/WifiConfiguration')]
  JWifiConfiguration = interface(JObject)
    ['{382E85F2-6BF8-4255-BA3C-03C696BC6451}']
    function _GetSSID: JString;
    procedure _SetSSID(Value: JString);
    function _GetBSSID: JString;
    procedure _SetBSSID(Value: JString);
    function _GethiddenSSID: boolean;

    procedure _SetwepTxKeyIndex(Value: integer);
    function _GetwepKeys: TJavaObjectArray<JString>;
    procedure _SetwepKeys(Value: TJavaObjectArray<JString>);

    property SSID: JString read _GetSSID write _SetSSID;

    property wepTxKeyIndex: integer read _GetwepTxKeyIndex write _SetwepTxKeyIndex;

  end;

  TJWifiConfiguration = class(TJavaGenericImport<JWifiConfigurationClass,
    JWifiConfiguration>)
  end;

您缺少cdecl所有方法的调用约定JWifiConfiguration。
