Android UnityPlayerActivity Action Bar

Question

I am building an Android application which includes a Unity 3d interactive experience.

I have imported the Unity project into Android Studio but when launched the activity is fullscreen and does not show the Android action bar.

How can I do this?

Integration Steps

• Create new Unity project.
• Export "Google Android Project" from Unity.
• Import project into Android Studio.

Attempted Solutions

• Changing the theme in the manifest.
• Setting the theme in the UnityPlayerActivity Java class.
• Overriding the Unity Android Manifest by placing a manifest with an updated theme in the Unity directory /Assets/Plugins/Android.
• Changing UnityPlayerActivity to extend AppCompatActivity. This will show the action bar but there is a white gap between it and the status bar.
• Setting "Screen.fullScreen = false;" in Unity SceneManager. This removes the immersive mode so that the Android status bar is visible.
• Turning off "Status Bar Hidden" in player settings. Appears to have no effect.
• Wrapping the UnityPlayer in a FrameLayout. This allows me to resize the the Unity as a view.

Answer 1

for Unity version 5.5 best way to avoid Immersive Mode in Android is to pass in the constructor not an Activity but to cast of the ApplicationContext to the Wrapper Context.

mUnityPlayer = new UnityPlayer((ContextWrapper) getApplicationContext());

That works because in the obfuscated UnityPlayer.class (in unity-classes.jar) there is a check of instance.

 private void h() {
     if(this.h instanceof Activity) {
        ((Activity)this.h).getWindow().setFlags(1024, 1024);
     }
 }

So if it's not an Activity the UnityPlayer.class doesn't set the flag.

Answer 2

I think I've found solution.
Change that line:

mUnityPlayer = new UnityPlayer(this);

so it creates your own UnityPlayer subclass, which overrides setFullscreen method (little bit hacky):

public class UnityPlayerWrapper extends UnityPlayer {
    public UnityPlayerWrapper(ContextWrapper contextWrapper) {
        super(contextWrapper);
    }

    @Override
    protected void setFullscreen(boolean b) {
        super.setFullscreen(false);
    }
}

In addition, please remove that line: requestWindowFeature(Window.FEATURE_NO_TITLE);
