How to get my wifi hotspot ssid in my current android system

问题

I have a problem that I couldn't find my wifi hotspot ssid in my Android system.
I found many information from google, but nothing helpful.
Please help me to solve it.

You can use WifiManager and WifiInfo for getting Wifi SSID

   WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
   WifiInfo wifiInfo = wifiManager.getConnectionInfo();
   Log.d("wifiInfo", wifiInfo.toString());
   Log.d("SSID",wifiInfo.getSSID());

Also add Permission in your Manifest file.

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE">
                                                            </uses-permission>

Here: http://www.androidjavadoc.com/2.3/android/net/wifi/WifiManager.html is the full documentation on the WifiManager.

Note that some of the methods are only available through inspection, as is the method you need getWifiApConfiguration.

WifiManager wifimanager = (WifiManager) getSystemService(WIFI_SERVICE);
Method[] methods = wifimanager.getClass().getDeclaredMethods();
for (Method m: methods) {           
    if (m.getName().equals("getWifiApConfiguration")) {
        WifiConfiguration config = (WifiConfiguration)m.invoke(wifimanager);

            // here, the "config" variable holds the info, your SSID is in
            // config.SSID
    }
}

O, and because this stuff is marked hidden, it can change or be completely removed in any future version of Android. So, don't rely on it too much on "official" apps, unless you make that very clear.

Have you tried using WifiInfo.getSSID() ?
