boolean onRightNetwork() {
    WifiManager wifiManager = (WifiManager) App.getContext()
                        .getSystemService(App.getContext().WIFI_SERVICE);
                WifiInfo wifiInfo = wifiManager.getConnectionInfo();

    return wifiInfo.getSSID().equals(NETWORK_NAME);
}

Run that in onResume, and just pop up a screen that says to connect to the right network if it returns false. You may also want to register a broadcast receiver to listen for wifi connect/disconnect events and perform this check as needed there as well.

i have a doubt! what if in future the SSID is changed? then don't we have to give another update just for a small change. — Deepak Vardhan, Feb 17 '18 at 15:46

Try this:

WifiManager wifiManager = (WifiManager)getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
wifiInfo.getSSID();

After getting the SSID, match it with your desired one. If the condition is met, then do whatever you want.

Mac address isn't what you want here, that identifies a router not a network – Gabe Sechan Mar 01 '16 at 12:42
Use SSID. That should identify the network. So you were on the right track. – Gabe Sechan Mar 01 '16 at 12:47

You can write your own logic for that in launcher Activity.

WifiManager wifiMgr = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiMgr.getConnectionInfo();
String name = wifiInfo.getSSID();

above code is to get name of currently connected network name, you can make condition if it matches your predefined name, allow user to use your application.

You could try something like this:

ConnectivityManager connManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

if (!mWifi.isConnected()) {
// exit app here
}

make sure You have proper permission in Your AndroidManifest.xml

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