Android action bar and title bar

Hello,

I'm not sure this is the correct place to post this but I think it's the most relevant.

I'm using Vuforia for Unity to create a very simple project. I have exported this project to Unity and followed the step to subclass my main activity with QCARPlayerActivity :

public class MainActivity extends QCARPlayerActivity

My applicationcompiles and runs successfully, I have even be able to add topviews such as buttons and labels (next step is fragment).

The only thing missing here is an action bar.

When I try the get the action bar with GetActionBar() in my main activity, the method returns null.

I red somewhere that it was because I had no Title Bar.

I also tried to force the app not to be in fullscreen without any success :

                        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);                        getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

I made sure to export with the statusBarHidden parameter set to false in the Unity parameters :

  <bool name="hide_status_bar">False</bool>

Before the splashscreen I see the title bar, but it's as if it is covered by the QCAR view, or removed by the QCARPlayerActivity.

So my question is : how do I get an action bar (and a title bar since it seems to be the same thing) with my activity subclassign from QCARPlayerActivity.

Thanks,
