GetDownloadInfo

PlayAsyncOperation< IDictionary< string, PlayAssetPackDownloadInfo >, AssetDeliveryErrorCode > GetDownloadInfo(
  IList< string > assetPackNames
)

Starts a PlayAsyncOperation to gather download information about the specified asset packs.

This includes download size and information about asset pack updates.

Details

Parameters

assetPackNames

A list of asset packs.

Returns

A PlayAsyncOperation with a Dictionary result keyed by asset pack name, containing download info about the specified packs.

GetDownloadSize

PlayAsyncOperation< long, AssetDeliveryErrorCode > GetDownloadSize(
  string assetPackName
)

Starts a PlayAsyncOperation to determine the download size in bytes of the specified asset pack.

If the specified asset pack's delivery mode is install-time, then the download size will always be 0.

IsDownloaded

bool IsDownloaded(
  string assetPackName
)

Returns whether or not the specified asset pack is available on disk.

Details

Parameters

assetPackName

The name of the desired asset pack.

Returns

True if the asset pack is available on disk and false if not.

RemoveAssetPack

PlayAsyncOperation< VoidResult, AssetDeliveryErrorCode > RemoveAssetPack(
  string assetPackName
)

Starts a PlayAsyncOperation to delete the specified asset pack from internal storage.

If the specified asset pack is currently being retrieved, this method will not cancel the retrieval. If the specified asset pack contains any AssetBundles that are already loaded into memory, the AssetBundles will not be unloaded.

Details
Returns	An async operation object used to monitor the asset pack removal. If the files are deleted successfully or if the files don't exist, the returned operation will complete successfully. Otherwise, the operation will complete with an error code.

RetrieveAssetBundleAsync

PlayAssetBundleRequest RetrieveAssetBundleAsync(
  string assetBundleName
)

Starts a PlayAssetBundleRequest to retrieve an asset pack containing only the specified AssetBundle.

Both the AssetBundle and asset pack must share the same name. Downloads the asset pack if it isn't already available on disk.

After download, the contained AssetBundle is loaded into memory before the request completes.

Details

Parameters

assetBundleName

The name of the requested AssetBundle.

Exceptions

ArgumentException

Thrown if there is already an active request with the specified name.

Returns

A request object used to monitor the asynchronous AssetBundle retrieval.

RetrieveAssetBundleAsync

PlayAssetBundleRequest RetrieveAssetBundleAsync(
  string assetBundleName,
  bool updateIfAvailable
)

Starts a PlayAssetBundleRequest to retrieve an asset pack containing only the specified AssetBundle.

Both the AssetBundle and asset pack must share the same name. Downloads the asset pack if it isn't already available on disk.

After download, the contained AssetBundle is loaded into memory before the request completes.

RetrieveAssetPackAsync

PlayAssetPackRequest RetrieveAssetPackAsync(

ShowCellularDataConfirmation

PlayAsyncOperation< ConfirmationDialogResult, AssetDeliveryErrorCode > ShowCellularDataConfirmation()

Shows a confirmation dialog for all currently downloading asset packs that are AssetDeliveryStatus.WaitingForWifi.

If the user accepts the dialog, then those asset packs are downloaded over cellular data.

A PlayAssetBundleRequest 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 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

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.

A PlayAssetBundleRequest is set to AssetDeliveryStatus.RequiresUserConfirmation If the download is not able to proceed without user consent. By showing this dialog, the app can ask the user if they accept downloading the asset packs through Google Play. If the app has not been installed by Play, 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.

Details
Returns	A PlayAsyncOperation{ConfirmationDialogResult, AssetDeliveryErrorCode} that completes once the dialog has been accepted, denied, or closed.
