Question

I want connect with specific WiFi network.Broadcast receiver get called only when we add correct password.And if user add wrong password than I unable to check password is valid or not.Because not getting called any callback method for this. This code is for android version 10 and above

Code for connect with wifi

@RequiresApi(Build.VERSION_CODES.Q)
private fun connectUsingNetworkSuggestion(ssid: String, password: String, securityType: String) {
   var  wifiManagerSugg = applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager
    var wifiNetworkSuggestion:WifiNetworkSuggestion
    if(password.isEmpty()){
        wifiNetworkSuggestion = WifiNetworkSuggestion.Builder()
                .setSsid(ssid)
                //.setWpa2Passphrase(password)
                .setIsAppInteractionRequired(true)
                .setIsUserInteractionRequired(true)
                .build()
    }else{
        wifiNetworkSuggestion = WifiNetworkSuggestion.Builder()
                .setSsid(ssid)
                .setWpa2Passphrase(password)
                .setIsAppInteractionRequired(true)
                .setIsUserInteractionRequired(true)
                .build()
    }


    // Optional (Wait for post connection broadcast to one of your suggestions)
    val intentFilter =
            IntentFilter(WifiManager.ACTION_WIFI_NETWORK_SUGGESTION_POST_CONNECTION)
    //boradcast receiver

    registerReceiver(broadcastReceiver, intentFilter)

    if(this::lastSuggestedNetwork.isInitialized){
        val status = wifiManagerSugg.removeNetworkSuggestions(listOf(lastSuggestedNetwork))
        Log.i("WifiNetworkSuggestion", "Removing Network suggestions status is $status")
    }

    //disconnect previous wifi access point
    //wifiManagerSugg.disconnect()
    //Thread.sleep(1000)
    wifiManagerSugg.removeNetworkSuggestions(listOf())

    val suggestionsList = listOf(wifiNetworkSuggestion)
    var status = wifiManagerSugg.addNetworkSuggestions(suggestionsList)
    Log.i("WifiNetworkSuggestion", "Adding Network suggestions status is $status")
    if (status == WifiManager.STATUS_NETWORK_SUGGESTIONS_ERROR_ADD_DUPLICATE) {
        Toast.makeText(this, "Suggestion Update Needed", Toast.LENGTH_LONG).show()
        // showToast("Suggestion Update Needed")
        status = wifiManagerSugg.removeNetworkSuggestions(suggestionsList)
        Log.i("WifiNetworkSuggestion", "Removing Network suggestions status is $status")

        //disconnect previous wifi access point
       // wifiManagerSugg.disconnect()
        //Thread.sleep(1000)
        wifiManagerSugg.removeNetworkSuggestions(listOf())

        status = wifiManagerSugg.addNetworkSuggestions(suggestionsList)
    }
    if (status == WifiManager.STATUS_NETWORK_SUGGESTIONS_SUCCESS) {
        lastSuggestedNetwork = wifiNetworkSuggestion
        lastSuggestedNetworkSSID = ssid
        // showToast("Suggestion Added")
        Toast.makeText(this, "Suggestion Added", Toast.LENGTH_LONG).show()
    }
    if (status != WifiManager.STATUS_NETWORK_SUGGESTIONS_SUCCESS) {
        // do error handling here
        Toast.makeText(this,"Something went wrong",Toast.LENGTH_LONG).show()
    }


}


val broadcastReceiver = object : BroadcastReceiver() {
    override fun onReceive(context: Context, intent: Intent) {
        if (intent.action.equals(WifiManager.ACTION_WIFI_NETWORK_SUGGESTION_POST_CONNECTION)) {
           
           // dialog.dismiss()
        }
    }
