DelegatingSandboxedUiAdapter
@ExperimentalFeatures.DelegatingAdapterApi
public final class DelegatingSandboxedUiAdapter implements SandboxedUiAdapter
A SandboxedUiAdapter that helps delegate calls to other uiAdapters.
When this adapter is set to the client's container, the adapter can switch the delegate uiAdapter, that serves the Session, without involving the client. For each new delegate, a session would be requested with all clients of this adapter.
One example use-case of these kind of UIAdapters is to support updating the provider of the UI without the client's involvement.

Public methods
addDelegateChangeListener
public final void addDelegateChangeListener(
@NonNull DelegatingSandboxedUiAdapter.DelegateChangeListener listener
)
addObserverFactory
public void addObserverFactory(
@NonNull SessionObserverFactory sessionObserverFactory
)
Adds a SessionObserverFactory with a SandboxedUiAdapter for tracking UI presentation state across UI sessions. This has no effect on already open sessions.
For each SandboxedUiAdapter.Session that is created for the adapter after registration is complete, SessionObserverFactory.create will be invoked to allow a new SessionObserver instance to be attached to the UI session. This SessionObserver will receive UI updates for the lifetime of the session. There may be one or more UI sessions created for a SandboxedUiAdapter, and a separate SessionObserverFactory.create call will be made for each one.
getDelegate
public final @NonNull Bundle getDelegate()
Fetches the current delegate which is a SandboxedUiAdapter Bundle.
openSession
public void openSession(
@NonNull Context context,
@NonNull IBinder windowInputToken,
int initialWidth,
int initialHeight,
boolean isZOrderOnTop,
@NonNull Executor clientExecutor,
@NonNull SandboxedUiAdapter.SessionClient client
)
Open a new session for displaying content with an initial size of initialWidthxinitialHeight pixels. client will receive all incoming communication from the provider of content. All incoming calls to client will be made through the provided clientExecutor. isZOrderOnTop tracks if the content surface will be placed on top of its window
removeDelegateChangeListener
public final void removeDelegateChangeListener(
@NonNull DelegatingSandboxedUiAdapter.DelegateChangeListener listener
)
removeObserverFactory
public void removeObserverFactory(
@NonNull SessionObserverFactory sessionObserverFactory
)
Removes a SessionObserverFactory from a SandboxedUiAdapter, if it has been previously added with addObserverFactory.
If the SessionObserverFactory was not previously added, no action is performed. Any existing SessionObserver instances that have been created by the SessionObserverFactory will continue to receive updates until their corresponding SandboxedUiAdapter.Session has been closed. For any subsequent sessions created for the SandboxedUiAdapter, no call to SessionObserverFactory.create will be made.
updateDelegate
public final void updateDelegate(@NonNull Bundle delegate)
Updates the delegate and notifies all listeners to process the update. If any listener fails process refresh we throw IllegalStateException. Cancellation of this API does not propagate to the client side.
