思考并回答以下问题：

using UnityEngine;
using UnityEditor;
using System.IO;

// 自动命名+打包
public class CreateAssetBundle : Editor
{
	// 自动命名
	[MenuItem("AssetBundle/01.SetAssetBundleName")]
	static void SetAssetBundleName()
	{
		Object[] objects = Selection.objects; // 鼠标选中对象，可多选

		foreach (Object o in objects)
		{
			string assetPath = AssetDatabase.GetAssetPath(o);
			// Debug.Log(assetPath); // Assets/Prefab/Cube.prefab
			AssetImporter assetImporter = AssetImporter.GetAtPath(assetPath);
			assetImporter.assetBundleName = o.name; // cube
			assetImporter.SaveAndReimport();
		}
		AssetDatabase.Refresh();
	}

	// 打包
	[MenuItem("AssetBundle/02.BuildAll")]
	static void BuildAll()
	{
		string path = Application.dataPath + "/AssetBundles/";
		// Directory类需要System.IO
		if (Directory.Exists(path))
		{
			Directory.Delete(path, true);
		}
		Directory.CreateDirectory(path);
		BuildPipeline.BuildAssetBundles(path, BuildAssetBundleOptions.None, BuildTarget.Android);
		AssetDatabase.Refresh();
	}
}
