RxJava 2 Android Examples - How to use RxJava 2 in Android
Hi, I am Amit Shekhar, I have mentored many developers, and their efforts landed them high-paying tech jobs, helped many tech companies in solving their unique problems, and created many open-source libraries being used by top companies. I am passionate about sharing knowledge through open-source, blogs, and videos.

RxJava 2.0 has been completely rewritten from scratch on top of the Reactive-Streams specification. The specification itself has evolved out of RxJava 1.x and provides a common baseline for reactive systems and libraries.
Add this in your build.gradle
compile 'io.reactivex.rxjava2:rxjava:X.X.X'
If you are using RxAndroid also, then add the following
compile 'io.reactivex.rxjava2:rxandroid:X.X.X'
Map
-> transform the items emitted by an Observable by applying a function to each item. Blog: RxJava Operator Map vs FlatMap
Zip
-> combine the emissions of multiple Observables together via a specified function and emit single items for each combination based on the results of this functionFilter
-> emit only those items from an Observable that pass a predicate testFlatMap
-> transform the items emitted by an Observable into Observables, then flatten the emissions from those into a single Observable. Blog: RxJava Operator Map vs FlatMap
Take
-> emit only the first n items emitted by an Observable. Blog for reference
Reduce
-> apply a function to each item emitted by an Observable, sequentially, and emit the final valueSkip
-> suppress the first n items emitted by an ObservableBuffer
-> periodically gather items emitted by an Observable into bundles and emit these bundles rather than emitting the items one at a timeConcat
-> emit the emissions from two or more Observables without interleaving them. Blog for reference
Replay
-> ensure that all observers see the same sequence of emitted items, even if they subscribe after the Observable has begun emitting itemsMerge
-> combine multiple Observables into one by merging their emissionsSwitchMap
-> transform the items emitted by an Observable into Observables, and mirror those items emitted by the most-recently transformed ObservableCompositeDisposable
