Examples with ControllerCb androidx.media3.session.MediaSession.ControllerCb used on opensource projects

Example 1 with ControllerCb

use of androidx.media3.session.MediaSession.ControllerCb in project media by androidx.

the class MediaLibrarySessionImpl method onSubscribeOnHandler.

public ListenableFuture<LibraryResult<Void>> onSubscribeOnHandler(ControllerInfo browser, String parentId, @Nullable LibraryParams params) {
    ControllerCb controller = checkStateNotNull(browser.getControllerCb());
    synchronized (lock) {
        @Nullable Set<String> subscription = subscriptions.get(controller);
        if (subscription == null) {
            subscription = new HashSet<>();
            subscriptions.put(controller, subscription);
        }
        subscription.add(parentId);
    }
    // Call callbacks after adding it to the subscription list because library session may want
    // to call notifyChildrenChanged() in the callback.
    // 
    // onSubscribe is defined to return a non-null result but it's implemented by applications,
    // so we explicitly null-check the result to fail early if an app accidentally returns null.
    ListenableFuture<LibraryResult<Void>> future = checkNotNull(callback.onSubscribe(instance, browser, parentId, params), "onSubscribe must return non-null future");
    // When error happens, remove from the subscription list.
    future.addListener(() -> {
        @Nullable LibraryResult<Void> result = tryGetFutureResult(future);
        if (result == null || result.resultCode != RESULT_SUCCESS) {
            removeSubscription(controller, parentId);
        }
    }, MoreExecutors.directExecutor());
    return future;
}

Example 2 with ControllerCb

use of androidx.media3.session.MediaSession.ControllerCb in project media by androidx.

the class MediaSessionImpl method dispatchRemoteControllerTask.

    try {
        ListenableFuture<SessionResult> future;
        int seq;
        @Nullable SequencedFutureManager manager = sessionStub.getConnectedControllersManager().getSequencedFutureManager(controller);

            seq = 0;
            // Tell that operation is successful, although we don't know the actual result.
            future = Futures.immediateFuture(new SessionResult(SessionResult.RESULT_SUCCESS));
        }
        ControllerCb cb = controller.getControllerCb();
        if (cb != null) {
            task.run(cb, seq);
        }
        return future;
    } catch (DeadObjectException e) {

        return Futures.immediateFuture(new SessionResult(RESULT_ERROR_SESSION_DISCONNECTED));
    } catch (RemoteException e) {
        // Currently it's TransactionTooLargeException or DeadSystemException.
        // We'd better to leave log for those cases because
        // - TransactionTooLargeException means that we may need to fix our code.
        // (e.g. add pagination or special way to deliver Bitmap)
        // - DeadSystemException means that errors around it can be ignored.
        Log.w(TAG, "Exception in " + controller.toString(), e);
    }

}

Example 3 with ControllerCb

            }
            return null;
