Application.temporaryCachePath  /var/mobile/Containers/Data/Application/app sandbox/Library/Caches 
Application.persistentDataPath  /var/mobile/Containers/Data/Application/app sandbox/Documents

Android:
Application.dataPath            /data/app/package name-1/base.apk 
Application.streamingAssetsPath jar:file:///data/app/package name-1/base.apk!/assets 
Application.temporaryCachePath  /storage/emulated/0/Android/data/package name/cache 
Application.persistentDataPath  /storage/emulated/0/Android/data/package name/files

Windows:

资源载入

1.IO方式

using(FileStream fs = FIle.Open(Application.streamingAssetsPath + "fileName",FileMode.Open)){
    //do something
}

2.WWW方式

方式1
using(WWW www = new WWW(Application.streamingAssetsPath + "fileName")){
    yield return www;
    //do something
}

方式2
WWWW www = new WWW(Application.streamingAssetsPath + "fileName");
try{
    yield return www;
    //do something
}finally{
    www.Dispose();
}

3.AssetBundle方式

string abPath = 
#if UNITY_ANDROID
Application.dataPath + "!assets";
#else
Application.streamingAssetsPath;
#endif
AssetBundle.LoadFromFile(abPath + "/fileName.unity3d");

---

1.Assets

AssetDatabase.LoadAssetAtPath("Assets/../sun.png");

只能在编辑器下获取资源对象。

2.Resources

Resources.Load("/../fileName");

同名资源，只会返回第一个符合名字的资源对象。

Resources.LoadAll("/../fileName");

返回所有符合的资源对象。

3.PresistentDataPath

可读写外部文件夹，不会被打入包中，只能WWW/IO加载。

4.StreamingAssets

原封不动打入包中，只能WWW/IO加载（AssetBundle除外）。
