```csharp
public static bool coreUnityAssetPacksDownloaded { get; }
```

### Remarks

Read-only. Returns `true` if all core Unity asset packs are downloaded. Otherwise, returns `false` if any core Unity asset packs aren't downloaded or if the [PlayCore plug-in](https://developer.android.com/guide/playcore) is missing.

Core Unity asset packs are asset packs that Unity creates automatically when it builds the Android app bundle. Unity only creates core asset packs if you enable **Split Application Binary** in Android Player settings or if you use [Texture Compression Targeting](/engine/6000.3/manual/platform-specific/android/building-and-delivering/distribution/google-play.md#texture-compression-targeting). To safely access assets in the streaming assets path, resources directory, or to safely load any scenes other than the first, only access them after this property returns `true`.

When the property returns `false`, check the download status of the core Unity asset packs. To do this, call [AndroidAssetPacks.GetCoreUnityAssetPackNames](/engine/6000.3/script-reference/unityengine/android/androidassetpacks/getcoreunityassetpacknames.md) to get the array of core Unity asset pack names, then call [AndroidAssetPacks.GetAssetPackStateAsync](/engine/6000.3/script-reference/unityengine/android/androidassetpacks/getassetpackstateasync.md) and pass in the names array. If the state indicates that the device hasn't yet downloaded an asset pack, or the device is not downloading an asset pack, call [AndroidAssetPacks.DownloadAssetPackAsync](/engine/6000.3/script-reference/unityengine/android/androidassetpacks/downloadassetpackasync.md) passing in the asset pack's name. If there are asset packs that have the `WaitingForWifi` status, ask the user to allow the application to download them using mobile data. To do this, call [AndroidAssetPacks.RequestToUseMobileDataAsync](/engine/6000.3/script-reference/unityengine/android/androidassetpacks/requesttousemobiledataasync.md).

If this property returns `false` and `GetCoreUnityAssetPackNames` returns an empty array, then the application doesn't have the PlayCore plugin. Unity automatically adds it as a dependency in unityLibrary's `build.gradle` file when it builds the Android application with asset packs.
