streamingAssetsPath 内文件读取

复制代码

public void Start(){
    StartCoroutine(ontest());

}
IEnumerator ontest(){
    string persistentDataPath = Application.persistentDataPath +"/01.txt";
    Debug.Log(" persistentDataPath : "+persistentDataPath);
    if(!File.Exists(persistentDataPath)){
        string fileName  = Application.streamingAssetsPath + "/01.txt";
        Debug.Log("  fileName :"+fileName);

            WWW www = new WWW(fileName);
            yield return www;
            if(!string.IsNullOrEmpty(www.error)){
                Debug.Log("==============load not error==========");

adb logcat -s Unity 打印的结果 
 

 

android　如上 无法用File.Exits(path) 判断文件是否存在(据说ios可以)

只能用www加载.

[csharp]  view plain copy

 #if UNITY_ANDROID
     IEnumerator Start()
     {
         string fullName = "jar:file://" + Application.dataPath + "!/assets/test.txt";
         WWW www = new WWW(fullName);
         yield return www;
         //加载完成后处理，有点delay
         print(www.text)
     }
 #else
     void Start ()
     {
         //Windows处理
     }
 #endif
