Create a custom asset pack

To create a custom asset pack, create a directory with a name that ends with .androidpack. You can place this directory anywhere in your project’s Assets directory, or any subdirectory.

Important: Unity doesn’t import assets from .androidpack directories, so you can’t use assets in custom asset packs directly in Unity scenes. To use assets from custom asset packs, you must manually access and load them dynamically at runtime. For information on how to do this, see Manage asset packs at runtime.

The following steps explain how to create a custom asset pack named MyAssets1:

1. 转到您要在其中创建资源包的目录。这可以直接在 Assets 或类似 Assets/CustomAssetPacks 的子目录中。
2. Create a new directory and call it MyAssets1.androidpack. To add any assets to the asset pack, place them inside this folder.
   Note: Unity doesn’t include empty asset packs in builds. Also, asset pack names must begin with a letter and consist of English alphanumeric characters or an underscore.
3. By default, the delivery mode is on-demand, which means that if you don’t change the delivery mode, you need to manually download the asset pack at runtime. For information on how to do this, see Manage asset packs at runtime.
4. To use a different delivery mode, create a file called build.gradle inside the custom asset pack directory. Paste the following into the file:

apply plugin: 'com.android.asset-pack'
assetPack {
    packName = "MyAssets1"
    dynamicDelivery {
        deliveryType = "fast-follow"
    }
}

这将交付模式设置为 fast-follow，这意味着 Google Play 在安装应用程序后会自动下载资源包。有关此文件格式的信息，请参阅集成资源交付 (Integrate asset delivery)。

Note: The packName you specify in the build.gradle file should match the asset pack directory name you set without the .androidpack extension.
