Deprecated Classes

Class and Description
rx.schedulers.ImmediateScheduler This type was never publicly instantiable. Use Schedulers.immediate().
rx.schedulers.NewThreadScheduler This type was never publicly instantiable. Use Schedulers.newThread().
rx.observers.TestObserver use the TestSubscriber instead.
rx.schedulers.TrampolineScheduler This type was never publicly instantiable. Use Schedulers.trampoline().

Deprecated Methods

Method and Description
rx.Observable.cache(int) Use Observable.cacheWithInitialCapacity(int) instead.
rx.Observable.create(Observable.OnSubscribe<T>) 1.2.7 - inherently unsafe, use the other create() methods for basic cases or see Observable.unsafeCreate(OnSubscribe) for advanced cases (such as custom operators)
rx.Notification.createOnCompleted(Class<T>) this method does the same as Notification.createOnCompleted() and does not use the passed in type hence it's useless.
rx.Observable.finallyDo(Action0) use Observable.doAfterTerminate(Action0) instead.
rx.plugins.RxJavaPlugins.getInstance() use the static methods of RxJavaHooks.
rx.observers.TestSubscriber.getOnCompletedEvents() use TestSubscriber.getCompletions() instead.
rx.Observable.groupBy(Func1<? super T, ? extends K>, Func1<? super T, ? extends R>, Func1<Action1<K>, Map<K, Object>>) since 1.3.7, use Observable.groupBy(Func1, Func1, int, boolean, Func1) instead which uses much less memory. Please take note of the usage difference involving the evicting action which now expects the value from the map instead of the key.
rx.plugins.RxJavaErrorHandler.handleError(Throwable)
rx.plugins.RxJavaCompletableExecutionHook.onCreate(Completable.OnSubscribe)
rx.plugins.RxJavaObservableExecutionHook.onCreate(Observable.OnSubscribe<T>)
rx.plugins.RxJavaSingleExecutionHook.onCreate(Single.OnSubscribe<T>)
rx.plugins.RxJavaCompletableExecutionHook.onLift(Completable.Operator)
rx.plugins.RxJavaSingleExecutionHook.onLift(Observable.Operator<? extends R, ? super T>)
rx.plugins.RxJavaObservableExecutionHook.onLift(Observable.Operator<? extends R, ? super T>)
rx.plugins.RxJavaSchedulersHook.onSchedule(Action0)
rx.plugins.RxJavaCompletableExecutionHook.onSubscribeError(Throwable)
rx.plugins.RxJavaSingleExecutionHook.onSubscribeError(Throwable)
rx.plugins.RxJavaObservableExecutionHook.onSubscribeError(Throwable)
rx.plugins.RxJavaSingleExecutionHook.onSubscribeReturn(Subscription)
rx.plugins.RxJavaObservableExecutionHook.onSubscribeReturn(Subscription)
rx.plugins.RxJavaCompletableExecutionHook.onSubscribeStart(Completable, Completable.OnSubscribe)
rx.plugins.RxJavaObservableExecutionHook.onSubscribeStart(Observable<? extends T>, Observable.OnSubscribe<T>)
rx.plugins.RxJavaSingleExecutionHook.onSubscribeStart(Single<? extends T>, Observable.OnSubscribe<T>)
rx.Observable.timer(long, long, TimeUnit) use Observable.interval(long, long, TimeUnit) instead
rx.Observable.timer(long, long, TimeUnit, Scheduler) use Observable.interval(long, long, TimeUnit, Scheduler) instead

Deprecated Constructors

Constructor and Description
rx.exceptions.CompositeException(String, Collection<? extends Throwable>) please use CompositeException.CompositeException(Collection)
rx.Single(Observable.OnSubscribe<T>) 1.2.1: Not recommended, use Single.Single(OnSubscribe) to avoid wrapping and conversion between the Observable and Single protocols.
