Unknown ssid ошибка

      serviceInfo = info.getSSID();

      if(serviceInfo != null && serviceInfo.contains("unknown ssid")) {
          NetworkInfo wifiInfo = connectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
          String wifiName = wifiInfo.getExtraInfo();
          if (wifiName.startsWith("\"")) {
              wifiName = wifiName.substring(1, wifiName.length());
          }
          if (wifiName.endsWith("\"")) {
              wifiName = wifiName.substring(0, wifiName.length() - 1);
          }
          serviceInfo = wifiName;
      }

This question has already been asked by many people, but the solution that worked for them is not working for me. I have tested on Android 8.1 and Android 9.0 and cannot get the name of the SSID.

Broadcast receiver for getting WiFi state changes:

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if(intent.getAction().equals(WifiManager.WIFI_STATE_CHANGED_ACTION) ||
                intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION) ||
                intent.getAction().equals(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION) ||
                intent.getAction().equals(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION) ||
                intent.getAction().equals(WifiManager.NETWORK_STATE_CHANGED_ACTION)) {
            setWifiIndicator();
        }
    }
};

The receiver is registered onCreate and unregistered in onDestroy, which I think is proper, and I’m seeing the log lines when the receiver is called.

in onCreate:

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(ScannerService.ACTION_READ_SCANNER);
intentFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
intentFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
intentFilter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
intentFilter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
intentFilter.addAction(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION);
registerReceiver(mReceiver, intentFilter);
setWifiIndicator();

setWifiIndicator is implemented thusly:

private void setWifiIndicator() {
    ConnectivityManager connMgr = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
    //getApplicationContext solves memory leak issues prior to Android N (must use Application Context to get wifi system service.
    WifiManager wifiMgr = (WifiManager)getApplicationContext().getSystemService(Context.WIFI_SERVICE);
    ImageView wifiIndicator = (ImageView)findViewById(R.id.wifi_indicator);
    TextView wifiSSID = (TextView)findViewById(R.id.wifi_ssid);

    try {
        if (wifiMgr != null) {
            if (wifiMgr.isWifiEnabled()) {
                //wifi is enabled.  toggle on wifi indicator.
                wifiIndicator.setImageResource(R.drawable.wifi_indicator);
                String ssid = wifiMgr.getConnectionInfo().getSSID();
                if (ssid != null) {
                    Log.v(this.getClass().getSimpleName(), "SSID: " + ssid + "  Supplicant State: " + info.getSupplicantState());
                    wifiSSID.setText(ssid);
                }
            } else {
                //wifi is disabled.  toggle off wifi indicator.
                wifiSSID.setText("");

                //check for 3G
                NetworkInfo mobileInfo = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
                if (mobileInfo != null && mobileInfo.getState().equals(NetworkInfo.State.CONNECTED)) {
                    wifiIndicator.setImageResource(R.drawable.cellular_indicator);
                } else {
                    wifiIndicator.setImageResource(R.drawable.down_indicator);
                }
            }
        } else {
            //check for 3G
            NetworkInfo mobileInfo = connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
            if (mobileInfo != null && mobileInfo.getState().equals(NetworkInfo.State.CONNECTED)) {
                wifiIndicator.setImageResource(R.drawable.cellular_indicator);
            } else {
                wifiIndicator.setImageResource(R.drawable.down_indicator);
            }
        }
    } catch(Exception e) {
        //catching anything thrown in this block just so it doesn't crash the program unnecessarily
        e.printStackTrace();
    }
}

My app already had permission for ACCESS_COARSE_LOCATION but I aslo added ACCESS_FINE_LOCATION just in case. getSSID() is till returning <unknown ssid>.

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.GET_TASKS" />

Perhaps it has to do with compile target SDK? I’m really clueless here.

gradle file:

apply plugin: ‘com.android.application’

    compileSdkVersion 28
    defaultConfig {
        applicationId "com.noneofyour.business"

How do I make my SSID visible?

You can typically find the SSID by selecting the Setup option, and then Wireless Settings. Enable SSID broadcast by selecting Visible for the Visibility Status.

What happens if SSID is disabled?

Disabling the SSID broadcast stops the router from sending out the wireless network’s name, making it invisible to users. However, this only hides the name from showing up on device lists of nearby networks. The network itself is still there, since people still need to use it.

What is SSID code for Wi-Fi?

The SSID (Service Set Identifier) is the name of your wireless network, also known as Network ID. This is viewable to anyone with a wireless device within reachable distance of your network. It’s recommended you set up a password so not just anybody can connect to your network.

Can someone hack my Internet connection?

It’s entirely possible that your router might have been hacked and you don’t even know it. By using a technique called DNS (Domain Name Server) hijacking, hackers can breach the security of your home Wi‑Fi and potentially cause you a great deal of harm.

What happens when you connect to an unknown Wi-Fi?

All information sent over an unsecured wireless network—one that doesn’t require a Wi-Fi Protected Access (WPA), WPA2 or WPA3 security code—is sent in plain text for anyone to intercept. Connecting to an open network potentially opens your device to anyone else on that same wireless network.

Should SSID be on or off?

Disabling the SSID Broadcast is one way of securing your wireless network. This procedure will prevent other users from detecting your SSID or your wireless network name when they attempt to view the available wireless networks in your area.

Should I Enable SSID on router?

Home networks don’t require the use of a visible SSID unless the network uses several different access points that devices roam between. If your network uses a single router, turning off this feature is a trade-off between the potential security benefits and a loss of convenience in setting up new home network clients.

Is SSID necessary?

An SSID is a unique student identifier that all K–12 public school students are required to have.

Is the SSID the same as the Wi-Fi name?

SSID is simply the technical term for a Wi-Fi network name. When you set up a wireless home network, you give it a name to distinguish it from other networks in your neighbourhood. You’ll see this name when you connect your devices to your wireless network.

Why can’t I join a wireless network?

Sometimes connection issues arise because your computer’s network adapter might not be enabled. On a Windows computer, check your network adapter by selecting it on the Network Connections Control Panel. Make sure the Wireless connection option is enabled.
