Step 1

Include following permission in manifest

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

Step2

Let Android know which class will be register for BroadCast Receiver.

<receiver android:name="ConnectivityReceiver_package_name.ConnectivityReceiver">
   <intent-filter>
      <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
   </intent-filter>
</receiver>

Step 3

Put your logic for various Network States.

public class ConnectivityReceiver extends BroadcastReceiver {

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

     String action = intent.getAction();

    boolean noConnectivity = intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY,false);

     if(noConnectivity){

         //Show Warning Message
         //Close Application the way i suggested
     }

    }
