在您可以使用 Kotlin 访问某些页面之前，如何让我的 Android 应用程序连接到特定的单个 wifi

Question

So i'm working on an Android application that should use WiFi to determine if a user was within a certain building and allow them to check-in....

Is it possible to only allow users to checkin once a particular Wifi network is detected instead? I would like to do this because we are in a building where I will like users of the app to access only one of the establment's WiFi, via its ssid before they can checkin/signin on the app...

Any thoughts on how to achieve this on kotlin please? I have tried to implement this though but not working:

    Private fun conWifi(context: Context){
    val wifiManager: WifiManager = context.applicationcontext.getSystemService(Context.WIFI_SERVICE) as WifiManager
    val wifiInfo: WifiInfo! = wifiManager.conectionInfo

   if (wifiInfo.ssid.equals("SamsungWifi")){

           // some codes like show another page

       }

       else{

          // Toast...
       }

    }

Then I called it on:

enter.setonClickListener() {it: View!

     conWifi(applicationContext)

}

Please don't be offended I typed with a phone, please someone should help me and format, thank you.

According to the doc :

If the SSID can be decoded as UTF-8, it will be returned surrounded by double quotation marks. Otherwise, it is returned as a string of hex digits. The SSID may be WifiManager#UNKNOWN_SSID , if there is no network currently connected or if the caller has insufficient permissions to access the SSID.

Prior to Build.VERSION_CODES.JELLY_BEAN_MR1 , this method always returned the SSID with no quotes around it.

Maybe you want to check the double quotation marks.
