I am working on an augment reality android app. I developed the app in unity using vuforia and then imported it in android studio as i wanted to design it in android studio. The activity name in generated project structure is `UnityPlayerActivity` which has no layout in the project. The activity is passed to `UnityPlayer`class and the layout is generated. This is some code of my `UnityPlayerActivity` activity.

```
protected UnityPlayer mUnityPlayer; // don't change the name of this variable; referenced from native code

// Setup activity layout
@Override protected void onCreate(Bundle savedInstanceState)
{
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    super.onCreate(savedInstanceState);

    getWindow().setFormat(PixelFormat.RGBX_8888); // <--- This makes xperia play happy

    mUnityPlayer = new UnityPlayer(this);
    setContentView(mUnityPlayer);
    mUnityPlayer.requestFocus();
}

```

as it uses that layout how can i design that activity by referencing it.
