Sonar Cocos Helper - Setting Up Google Play Game Services on Android Studio

Android Studio 2.3.3 (LATEST)

Cocos2d-x 3.15.1 (LATEST)

I tested on Debug.

It's my first experience with Cocos2d-x Game Engine, I developed an Android Game using Cocos2d-x, all it's fine but when I tried to show the achievements it shows me an error like this :

java.lang.NullPointerException
                            at sonar.systems.framework.SonarFrameworkFunctions.showAchievements(SonarFrameworkFunctions.java:432)

My Code when I click to show the achievements :

SonarCocosHelper::GooglePlayServices::showAchievements();

My Google Play Achievement (I removed the ID from this photo):

I searched already for solutions in relationship with Android Studio but the results are very rare, I don't know what is the solution and what this the reason for this error.

Thank you,

I founded a solution but now I guess it's just a dirty fix, first the problem is in the GooglePlayServices.java and exactly in onStart method : Null pointer Exception because mHelper is Null.

@Override
    public void onStart() 
    {
        mHelper.onStart((Activity) ctx);
    }

Let us a little further why it generates null, so :

1. SonarFrameworkFunctions.java

when we want to call GooglePlayServices constructor from SonarFrameworkFunctions.java :

 //GOOGLE PLAY SERVICES
    if (SonarFrameworkSettings.USE_GOOGLE_PLAY_GAME_SERVICES)
    {
        String packageName = "sonar.systems.frameworks.GooglePlayServices.GooglePlayServices";
        googlePlayServices = (InstantiateFramework(packageName) != null) ? InstantiateFramework(packageName) : new Framework();
    }

2. Method : InstantiateFramework in SonarFrameworkFunctions.java

public static Framework InstantiateFramework(String packageName)
{
    Framework tmp = null;
    try
    {
        tmp = (Framework) Class.forName(packageName).getConstructor().newInstance();
        tmp.SetActivity(((SonarFrameworkActivity) app));
    } catch (InstantiationException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IllegalAccessException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IllegalArgumentException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InvocationTargetException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (NoSuchMethodException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (ClassNotFoundException e)
    {
        e.printStackTrace();
        Log.e("Class not found", "class doesn't exist or bad package name " + packageName);
    }
    return tmp;
}

The constructor is empty so there is only a method called onCreate that instantiate and prepare the mHelper to access to all functionalities of Google Play Services.

Solution (Dirty Fix):

GooglePlayServices.java

public GooglePlayServices() 
    {
       mHelper=getGameHelper();
    mHelper.setup(this);
    }
