Public methods

cancel

public abstract AiPackStates cancel (List<String> packNames)

Requests to cancel the download of the specified AI packs.

Note: Only active downloads can be canceled.

Parameters
packNames List

Returns
AiPackStates The new state for all specified packs.

clearListeners

public abstract void clearListeners ()

Unregisters all listeners previously added using registerListener(AiPackStateUpdateListener).

fetch

public abstract Task<AiPackStates> fetch (List<String> packNames)

Requests to download the specified AI packs.

This method will fail if the app is not in the foreground.

Parameters
packNames List

Returns
Task<AiPackStates> the state of all specified pack names

getAiAssetLocation

public abstract AiAssetLocation getAiAssetLocation (String packName, 
                String assetPath)

[advanced API] Returns the location of an AI asset in a pack, or null if the AI asset is not present in the given pack.

You don't need to use this API for common use-cases: you can use the standard File API for accessing AI assets from packs that were extracted into the filesystem; and you can use Android's AssetManager API to access AI assets from packs that were installed as APKs.

This API is useful for game engines that don't use Asset Manager and for developers that want a unified method to access AI assets, independently from the delivery mode.

Parameters
packName String

assetPath String

Returns
AiAssetLocation

getPackLocation

public abstract AiPackLocation getPackLocation (String packName)

Returns the location of the specified AI pack on the device or null if this pack is not downloaded.

The files found at this path should not be modified.

Parameters
packName String

Returns
AiPackLocation

getPackLocations

public abstract Map<StringAiPackLocation> getPackLocations ()

Returns the location of all installed AI packs as a mapping from the AI pack name to an AiPackLocation.

The files found at these paths should not be modified.

Returns
Map<StringAiPackLocation>

getPackStates

public abstract Task<AiPackStates> getPackStates (List<String> packNames)

Requests download state or details for the specified AI packs.

Do not use this method to determine whether an AI pack is downloaded. Instead use getPackLocation(String).

Parameters
packNames List

Returns
Task<AiPackStates>

registerListener

public abstract void registerListener (AiPackStateUpdateListener listener)

Registers a listener that will be notified of changes to the state of pack downloads for this app. Listeners should be subsequently unregistered using unregisterListener(AiPackStateUpdateListener).

Parameters
listener AiPackStateUpdateListener

removePack

public abstract Task<Void> removePack (String packName)

Deletes the specified AI pack from the internal storage of the app.

Use this method to delete AI packs instead of deleting files manually. This ensures that the AI Pack will not be re-downloaded during an app update.

If the AI pack is currently being downloaded or installed, this method does not cancel the process. For this case, use cancel(List) instead.

Parameters
packName String

Returns
Task<Void> A task that will be successful only if files were successfully deleted.

showConfirmationDialog

public abstract boolean showConfirmationDialog (ActivityResultLauncher<IntentSenderRequest> activityResultLauncher)

Shows a dialog that asks the user for consent to download packs that are currently in either the AiPackStatus.REQUIRES_USER_CONFIRMATION state or the AiPackStatus.WAITING_FOR_WIFI state.

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 pack requests to be cancelled. These packs should be requested again after the app restarts.

The confirmation activity returns one of the following values:

Parameters
activityResultLauncher ActivityResultLauncher: an activityResultLauncher to launch the confirmation dialog.

Returns
boolean whether the confirmation dialog has been started.

unregisterListener

public abstract void unregisterListener (AiPackStateUpdateListener listener)

Unregisters a listener previously added using registerListener(AiPackStateUpdateListener).

Parameters
listener AiPackStateUpdateListener
