Thoughts on automatically generating materials

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using System.IO;

public class BuildMaterial : UnityEditor.AssetModificationProcessor
{

    //The path of the generated Material
    private static string MaterialsPath = "Assets/Resources/Skin/";

    // Create a menu button and manually call to create a material
    [MenuItem ("HETools/BuildMaterials")]
    static void CreateMateral ()
    {
	//Get the list of objects
        Object[] selectObject = Selection.objects;

        List<string> path = new List<string> ();

	//Get the resource path from the object list
        foreach (Object obj in selectObject) {
            path.Add (AssetDatabase.GetAssetPath (obj));
        }

	//Assign the path to the CreateOneMaterial function to create the material
        foreach (string p in path) {
            CreateOneMateral (p);
        }
        System.GC.Collect ();
    }

    // Monitor the addition of assets resources, and find that the specified directory ThemeTile has a newly added texture, and automatically generate materials
    public static void OnWillCreateAsset (string path)
    {
        int index = path.LastIndexOf (".");
	//return file type
        string file = path.Substring (index);
	//Extract the separate file name of the path
        string[] pathArr = path.Split ('/');
	
	/ / Determine whether it is the specified resource folder
        if (pathArr [pathArr.Length - 3] != "ThemeTile")
            return;

	//Assign the path to the CreateOneMaterial function to create the material
        CreateOneMateral (path);
        System.GC.Collect ();
    }

    // create shader
    static void CreateOneMateral (string p)
    {
	//replace suffix name
        p = p.Replace (".meta", "");
        Debug.Log ("CreateOneMateral from path: " + p);


        int pos = p.LastIndexOf ('/');


        if (pos == -1)
            return;

        string[] strArr = p.Split ('/');

        string themeIDStr = strArr [strArr.Length - 2];

        Texture textur = (Texture)AssetDatabase.LoadAssetAtPath (p, typeof(Texture)) as Texture;//Load material texture

        string name = strArr [strArr.Length - 1];

        int y = name.IndexOf ('.');
        name = name.Substring (0, y);
        Material mater = new Material (Shader.Find ("Mobile/VertexLit"));//Create a new material and select the corresponding shader
        mater.mainTexture = textur;//Put the texture on the material

        AssetDatabase.CreateAsset (mater, MaterialsPath + themeIDStr + "/" + name + ".mat");//New material resource
	Debug.Log(AssetDatabase.GetAssetPath(mater));
    }
}

This does not automatically generate materials, but I don't know where the code problem is. Does anyone know if they can help? This code is not written by myself, but copied from a certain big guy on the Internet.
