What is the workaround code to detect network changes from Nougat and further android versions >

I am using below code to detect network changes 

public class NetworkStateListener extends BroadcastReceiver {

public static int NETWORK_CONNECTED_TYPE_WIFI = 1;
public static int NETWORK_CONNECTED_TYPE_MOBILE = 2;
public static int NO_NETWORK_CONNECTIVITY = 0;
public static int TYPE_NOT_KNOWN = -1;

private static final List<NetworkStateChangeListener> LISTENERS = new CopyOnWriteArrayList<>();

@Override
public void onReceive(Context context, Intent intent) {

    int status = getConnectivityStatus(context, intent);
    networkChecking(status);

}

private void networkChecking(int noNetworkConnectivity) {
    for (NetworkStateChangeListener mlistener : LISTENERS) {
        if (mlistener != null) {
            mlistener.onNetworkStateChanged(noNetworkConnectivity);
        }
    }
}


public static void registerNetworkState(NetworkStateChangeListener listener) {
    synchronized (LISTENERS) {
        if (!LISTENERS.contains(listener)) {
            LISTENERS.add(listener);
        }
    }
}

public static void unregisterNetworkState(NetworkStateChangeListener listener) {
    LISTENERS.remove(listener);
}


public static int getConnectivityStatus(Context context, Intent intent) {


    if (intent.getExtras() != null) {
        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetwork = cm.getActiveNetworkInfo();

        if (activeNetwork!=null) {
            if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI){
                return NETWORK_CONNECTED_TYPE_WIFI;
            }

            if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE){
                return NETWORK_CONNECTED_TYPE_MOBILE;
            }

        }
        return NO_NETWORK_CONNECTIVITY;
    }

    return TYPE_NOT_KNOWN;
}

}

and initialising below intent filters in AndroidManifest.xml

<receiver android:name=".utils.network.NetworkStateListener">
        <intent-filter>
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
        </intent-filter>
    </receiver>

This code is working fine for below Marshmallow devices 6.0.1. But from 7 Nougat onwards, its not working.

What is the code change in Nougat?

Any code or gist will be appreciated. Thanks in advance.

Find the solution:

Register programmatically like this

IntentFilter intentFilter = new IntentFilter(); 
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) { // **For Nougat**
    intentFilter.addAction(ConnectivityManager.CONNECTIVITY_ACTI‌​ON); 
} else {
    intentFilter.addAction(ConnectivityManager.CONNECTIVITY_CHANGE));   
}

registerReceiver(new NetworkConnectionReceiver(), intentFilter);
