    You really need to support the back button in android but Unity doesn't give you simple functions to handle this, you kind of have to google how to handle it - there is no Android.OnBackButton or Android.MoveToBack for when on main menu.
    Would it be better to have some android-specific calls just to make code easier and more clear or does it just go against Unity's cross-platform API?

    Code (CSharp):
    1. //back button code:
    2. if (Input.GetKeyDown(KeyCode.Escape)) { }
    3.  
    4. //to send app into background (kinda awkward?)
    5. AndroidJavaObject activity = new AndroidJavaClass( "com.unity3d.player.UnityPlayer" ).GetStatic<AndroidJavaObject>( "currentActivity" );
    6. activity.Call<bool>( "moveTaskToBack", true );
    7. activity.Dispose();
