Description

My customer reported that his android shows <unknown ssid> in app but I can’t reproduce it in my devices and emulator whatever android versions. Coincidently, I found some one post a blog that a similar issue for some mobile device - vivo x21iA / vivo x20.

I’ve tested in these two devices and the issue surely could be reproduced. It’s undoubtedly not the bug of plugin. It should be a bug of some firmwares or else, but I can’t tell my customers to contact the mobile manufacturer to solve this problem.

Thus, I have modified the code(WifiWizard2.java) as below(get SSID by another API):

      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;
      }

And it works now. Hope this would help someone.

Versions

vivo x21iA / vivo x20 and maybe more Android 8.1 WifiWizard2 3.x

@gorebill You may wanna try calling WifiWizard2.requestPermission() manually. In your case info.requestPermission(). Experienced the same while using android 8.1+
