NetworkOnMainThreadException in IntentService

I make network calls from an IntentService, but still get a NetworkOnMainThreadException. I understand that IntentService always runs on a workflow, so I am surprised to see this. The key point may be that my IntentService calls a static helper class that makes network calls. A static helper class is created in my main Application class.

I thought this would still be executed in the IntentService workflow. What am I missing?

Honestly, I prefer attentive informational discussions on quick code fixes. But if a code is needed, the code must be provided:

//MyApplication.java
public class MyApplication extends Application{

private static NetworkUtils utils;

    @Override
    public void onCreate() {
        super.onCreate();
        utils = new NetworkUtils(this);
        ...
    }
    ...
}

//NetworkUtils.java
public class NetworkUtils {

    private static Context context;
    private static final Gson gson = new Gson();

    public NetworkUtils(Context context) {
        this.context = context;
    }

    public static final DataResponse login(String email, String password) {
        //*** NetworkOnMainThreadException OCCURS HERE ***
        DataResponse response = HttpConnection.put(url, json);
        ...
        return response;
    }
    ...
}

//LoginService.java
public class LoginService extends IntentService {

    public LoginService() {
        super("LoginService");
    }

    @Override
    public void onStart(Intent intent, int startId) {
        onHandleIntent(intent);
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        Bundle bundle = new Bundle();
        DataResponse response = NetworkUtils.login(email, password);
        ...
        bundle.putBoolean(MyConstants.ExtraKeys.LOGGED, response.success);
        MainApplication.getApplicationInstance().sendBroadCast(MyConstants.Actions.LOGIN, bundle);
    }
}

//LoginActivity.java
public class LoginActivity extends ActionBarActivity implements IDialogClickListener {
    ...
    public void onLoginButtonPressed() {
        Intent intent = new Intent(MainApplication.getApplicationInstance(), LoginService.class);
        this.startService(intent);
    }
}

In addition, Logcat:

Decision

, onHandleIntent. LoginService.java :

@Override 
public void onStart(Intent intent, int startId) { 
    onHandleIntent(intent); 
} 

, onHandleIntent , onStart (, -, ).
