AssetBundle 在Android机子上进行读取


我看到官方文档中说明：
Note that bundles are not fully compatible between platforms.
A bundle built for any of the standalone platforms (including webplayer) can be loaded on any of those platforms but not on iOS or Android.
Furthermore, a bundle built for iOS is not compatible with Android and vice versa.

但是我们看到，用以下步骤进行在Android机子上使用AssetBundle

重点有2点：
Use the option "BuildTarget.Android".
Describe the path with triple slash "file:///"

以下是步骤：
Delete directories "Per Texture Materials", "assetbundles", and so on.  把已经导出过的包删掉
Use the option "BuildTarget.Android" to all "BuildPipeline.BuildAssetBundle".   要把BuildTarget为Android平台！！！
Run these on Editor. Character Generator/Generate Materials Character Generator/Create Assetbundles Character Generator/Update Character Element Database  
Copy Assetbundles database to Android device which like "/mnt/sdcard/assetbundles/"  把这些包放到Android的指定目录下
Modify AssetbundleBaseURL. (the point was "file:///") 修改获取AssetbundleBaseURL基础路径的地址

public static string AssetbundleBaseURL
{
get
{
if (Application.platform == RuntimePlatform.WindowsWebPlayer || Application.platform == RuntimePlatform.OSXWebPlayer)
{
return Application.dataPath + "/assetbundles/";
}
else if (Application.platform == RuntimePlatform.Android)
{
return "file:///mnt/sdcard/assetbundles/";
}
else
{
return "file://" + Application.dataPath + "/../assetbundles/";
}
}
}
