AssetBundle 在Android机子上进行读取 .-优快云博客

本文档详细介绍了如何在Unity中为Android平台构建并使用AssetBundles。通过设置正确的BuildTarget及路径，可以实现在Android设备上的资源热更新。文中还提供了具体的步骤指导，包括清理旧资产包、设置构建目标、复制数据到设备等。

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/";
        }
    }
}
