Introduction to Reactive Programming - RxJava and RxAndroid with samples plus comparison with plain old Java (Imperative) style of Programming. The following samples will have fundamental concepts that are required for getting started with Reactive Programming.

• BasicRxJavaSampleFragment - Basic Observable, Observer and Subscription example. Emitting list of animal names.
• RxJavaDisposableSampleFragment - Introduced Disposable to dispose the subscription.
• RxJavaOperatorSampleFragment - Introducing filter() operator to filter out the animal names starting with letter b.
• RxJavaCompositeSampleFragment - Introduced CompositeDisposable and DisposableObserver. Also Example of chaining of operators. map() and filter() operators are used together.
• BasicRxJavaCompactSampleFragment - Basic Observable, Observer with inline subscriber that implements OnNext() and OnError() handlers

• APICallAsyncFragment - Using AsyncTask, making a network call (Just for comparison)
• APICallRxJavaFragment - Making similar network call using RxJava and iterating over list using flatMap()

• APICallCoroutinesFragment - Making similar network call using Coroutines (Again for comparison)
• APICallHelperCoroutinesFragment - Making similar network call using Coroutines with helper methods (Again for comparison)

• Androidhive - Code samples and exaplanation
