如何在使用unity创建的android应用中显示导航栏

Question

I'm creating android app with Unity. Although I deleted this statement

AndroidManifest.xml

android:theme="@android:style/Theme.NoTitleBar"

It's still not showing navigation bar in my app. Can you help me someone?

Folder Path is MyUnityProject/Assets/Plugins/Android/AndroidManifest.xml and AndroidManifest.xml

This is achieved by turning off full screen mode.

#if UNITY_ANDROID
    Screen.fullScreen = false;
#endif
