权限添加 ：Player settings -- Other settings -- write permission的设置 Sdcard。这个是在Unity编辑器里打包的情况。
如果导出到studio 里面的话，可自行修改Manifest文件。
加载的 /storage/emulated/0/ProjectName/image.jpg,
image = this.GetComponentInChildren<Image>();
Debug.Log("IO加载用时: image = this.GetComponent<Image> ========== " + image);
Debug.Log("IO加载: Application.dataPath " + Application.dataPath );
// Application.dataPath /data/app/com.putao.ptx.core-1/base.apk
Debug.Log("IO加载: Application.persistentDataPath " + Application.persistentDataPath);
// Application.persistentDataPath /storage/emulated/0/Android/data/com.putao.ptx.core/files
Debug.Log("IO加载:GameObject.Find" + GameObject.Find("Canvas/Avator").GetComponent<Image>());
// /data/user/0/com.putao.paichallenge/cache/20170524_130527.jpg
// path ======= "/storage/emulated/0/ProjectName/image.jpg"
FileStream fileStream = new FileStream(path, FileMode.Open, FileAccess.Read);
fileStream.Seek(0, SeekOrigin.Begin);
//创建文件长度缓冲区
byte[] bytes = new byte[fileStream.Length];
//读取文件
fileStream.Read(bytes, 0, (int)fileStream.Length);
//释放文件读取流
fileStream.Close();
fileStream.Dispose();
fileStream = null;
//创建Texture
int width = 300;
int height = 372;
Texture2D texture = new Texture2D(width, height);
texture.LoadImage(bytes);
//创建Sprite
Sprite sprite = Sprite.Create(texture, new Rect(0, 0, texture.width,texture.height), new Vector2(0.5f, 0.5f));
image.sprite = sprite;
log上可以看出来 android上 getExternalFilesDir("") 和 Unity里面的Application.persistentDataPath是一致的
url= "file://"+ "/storage/emulated/0/ProjectName/image.jpg"
根本不是加"jar:file://..."
public void LoadByWWW(String path)
{
StartCoroutine(doLoadByWWW(path));
}
IEnumerator doLoadByWWW(String path)
{
string url = "file://" + "/storage/emulated/0/PaiChallenge/image.jpg";
Debug.Log("doLoadByWWW == url ================== " + url);
WWW w = new WWW(url);
yield return w;
if (w.isDone)
{
Sprite sprite = Sprite.Create(w.texture, new Rect(0, 0, w.texture.width, w.texture.height), new Vector2(0.5f, 0.5f));
GameObject.Find("Canvas/Avator").GetComponent<Image>().sprite = sprite;
}
