A [PlayAssetBundleRequest](https://developer.android.com/reference/unity/class/Google/Play/AssetDelivery/PlayAssetBundleRequest#classGoogle_1_1Play_1_1AssetDelivery_1_1PlayAssetBundleRequest) is set to AssetDeliveryStatus.WaitingForWifi if the user is currently not on a Wi-Fi connection and the AssetBundle is large or the user has set their download preference in the [Play](https://developer.android.com/reference/unity/namespace/Google/Play#namespaceGoogle_1_1Play) Store to only download apps over Wi-Fi. By showing this dialog, the app can ask the user if they accept downloading the asset packs over cellular data instead of waiting for Wi-Fi.
| Details ||
|---|---|
| **Returns** | A PlayAsyncOperation{ConfirmationDialogResult, AssetDeliveryErrorCode} that completes once the dialog has been accepted, denied, or closed. |
### ShowConfirmationDialog
```c#
PlayAsyncOperation< ConfirmationDialogResult, AssetDeliveryErrorCode > ShowConfirmationDialog()
```
Shows a dialog that asks the user for consent to download packs that are currently in either the AssetDeliveryStatus.RequiresUserConfirmation state or the AssetDeliveryStatus.WaitingForWifi state.

If the app has not been installed by [Play](https://developer.android.com/reference/unity/namespace/Google/Play#namespaceGoogle_1_1Play), an update may be triggered to ensure that a valid version is installed. This will cause the app to restart and all asset requests to be cancelled. These assets should be requested again after the app restarts.
A [PlayAssetBundleRequest](https://developer.android.com/reference/unity/class/Google/Play/AssetDelivery/PlayAssetBundleRequest#classGoogle_1_1Play_1_1AssetDelivery_1_1PlayAssetBundleRequest) is set to AssetDeliveryStatus.WaitingForWifi if the user is currently not on a Wi-Fi connection and the AssetBundle is large or the user has set their download preference in the [Play](https://developer.android.com/reference/unity/namespace/Google/Play#namespaceGoogle_1_1Play) Store to only download apps over Wi-Fi.
