Error(s) when "switching platform" to Android or IOS

[hapythereal]

These are the errors:

 

(YELLOW)

You are trying to create a MonoBehaviour using the 'new' keyword.  This is not allowed.  MonoBehaviours can only be added using AddComponent(). Alternatively, your script can inherit from ScriptableObject or no base class at all
UnityEngine.MonoBehaviour:.ctor ()
UnityStandardAssets.Utility.PlatformSpecificContent:.ctor () (at Assets/General Things/Standard Assets/Utility/PlatformSpecificContent.cs:30)
UnityEditor.Build.BuildPipelineInterfaces:InitializeBuildCallbacks (UnityEditor.Build.BuildPipelineInterfaces/BuildCallbacks)
 

 

 

 

(YELLOW)

UnityEngine.MonoBehaviour:.ctor ()
UnityStandardAssets.CrossPlatformInput.MobileControlRig:.ctor ()
UnityEditor.Build.BuildPipelineInterfaces:InitializeBuildCallbacks (UnityEditor.Build.BuildPipelineInterfaces/BuildCallbacks)
 

 

 

 

(RED)

NullReferenceException

How can I fix them? I am a newbie when it comes to scripting.
