| Type                                                               | Description                                                                                                                                                                                                                                                                           |

| [string\[\]](https://learn.microsoft.com/dotnet/api/system.string) | An array of asset pack names for core Unity asset packs with the fast-follow or on-demand delivery type. An empty array if Unity didn't create any core asset packs with these delivery types, or if the [PlayCore plug-in](https://developer.android.com/guide/playcore) is missing. |

### Remarks

Core Unity asset packs are asset packs that Unity creates automatically when it builds the Android app bundle. Unity creates core asset packs only when you enable **Split Application Binary** in Android Player settings.

This method uses PlayCore APIs, therefore it can only return names of asset packs that use the fast-follow or on-demand delivery types. If this method returns an empty array, to differentiate between the two potential causes, check the [AndroidAssetPacks.coreUnityAssetPacksDownloaded](/engine/6000.5/script-reference/unityengine/android/androidassetpacks/coreunityassetpacksdownloaded.md) property.

You can pass the asset pack names that this method returns to other methods such as [AndroidAssetPacks.GetAssetPackStateAsync](/engine/6000.5/script-reference/unityengine/android/androidassetpacks/getassetpackstateasync.md) or [AndroidAssetPacks.DownloadAssetPackAsync](/engine/6000.5/script-reference/unityengine/android/androidassetpacks/downloadassetpackasync.md) to get status information or to start the download. However, calling [AndroidAssetPacks.RemoveAssetPack](/engine/6000.5/script-reference/unityengine/android/androidassetpacks/removeassetpack.md) with the names returned by this method has no effect.
