unity读取Android本地图片

一、安卓读取路径

安卓路径：“file:///storage/emulated/0/”+自己图片的路径
例：“file:///storage/emulated/0/small.jpg”

二、unity搭建

使用UI简单搭个界面
在这里插入图片描述

三、新建一个脚本

代码内容如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Networking;
using UnityEngine.Android;public class Test : MonoBehaviour
{string url;public InputField input;public Button btn;public RawImage im;void Start(){
#if UNITY_ANDROID//安卓平台要请求从外部设备读写权限，如果安装后通过了权限请求，则以后这个APP就不会弹出请求权限框//但若安装后请求多次权限，都不通过，则多次后就不会弹出请求权限框//请求从 （SD 卡等）外部存储读取的权限if (!Permission.HasUserAuthorizedPermission(Permission.ExternalStorageRead)){Permission.RequestUserPermission(Permission.ExternalStorageRead);}//请求 写入外部存储（如 SD 卡）的权限       if (!Permission.HasUserAuthorizedPermission(Permission.ExternalStorageWrite)){Permission.RequestUserPermission(Permission.ExternalStorageWrite);}
#endifbtn.onClick.AddListener(BtnOnClick);url = "file:///storage/emulated/0/small.jpg";}public void BtnOnClick(){url = input.text;StartCoroutine(getMap());}IEnumerator getMap(){UnityWebRequest webRequest = UnityWebRequestTexture.GetTexture(url);yield return webRequest.SendWebRequest();//等待请求完成while (!webRequest.isDone){yield return null;}if (string.IsNullOrEmpty(webRequest.error)){Texture2D texture2D = DownloadHandlerTexture.GetContent(webRequest);if (texture2D){im.texture = texture2D;}}else{Debug.Log("失败");}}
}
