Hi My project's requirement is that I need to connect to any wifi network automatically from the phone app when the user selects the ssid from a list (with accompanying password if any). I came across this discussion on stackoverflow. I am no java expert so i wonder if anybody can help to get this working in Delphi ? Thank you very much

Hi Dave This is the code that im using. Although people in Stackoverflow have had this working for them i can't seem to get it to. Perhaps a mistake in the implementation, not sure. The stackoverflow link i referred to is <here > Regards ----------------------------------------------------------------------------------------------------------------------- var WifiManager: JWifiManager; WifiInfo: JWifiInfo; WifiManagerObj: JObject; procedure ConnectToSSID(aSSID,aPWD: string; Memo: TMemo); var count, i, j: Integer; ScanResult: JScanResult; conf,WinConf: JWifiConfiguration; s,ScanCaps: string; IPAddr: TIdBytes; networkSSID,networkPass: Jstring; wManager: JWifiManager; WObject,wConfObj: JObject; networkID: Integer; List: JList; isDisconnected, isEnabled, isReconnected : Boolean; begin WifiManagerObj := SharedActivityContext.getSystemService(TJContext.JavaClass.WIFI_SERVICE); WifiManager := TJWifiManager.Wrap((WifiManagerObj as ILocalObject).GetObjectID); WifiInfo := WifiManager.getConnectionInfo(); Conf := TJWifiConfiguration.JavaClass.init; networkSSID := StringToJString('"' + aSSID + '"'); networkPass := StringToJString('"' + aPwd + '"'); for i := 0 to WifiManager.getScanResults.size - 1 do begin ScanResult := TJScanResult.Wrap((WifiManager.getScanResults.get(i) as ILocalObject).GetObjectID); S := JStringToString(ScanResult.SSID); ScanCaps := JStringToString(Scanresult.capabilities); ScanCaps := UpperCase(ScanCaps); if (S = aSSID) then begin Memo.Lines.Add('Item clicked, SSID ' + S + ' Security : ' + JStringToString(scanResult.capabilities)); conf.SSID := networkSSID; //"\"" + networkSSID + "\""; // Please note the quotes.

Hi Rollo62, Thank you , the wifi settings page code is useful though i still cannot connect to a desired SSID using java code. I wonder if anybody has ever implemented this .... Regards
