• Functional Programming is a model of programming that transform and compose stream of immutable sequences by applying map, filter and reduce. Events are immutable because you can't change history.
• Reactive Programming is a model of programming focuses on data flow and change propagation.
• ReactiveX is an API that focuses on asynchronous composition and manipulation of observable streams of data or events by using a combination of the Observer pattern, Iterator pattern, and features of Functional Programming.
• RxJava is the open-source implementation of ReactiveX in Java.
• RxJava is a Java VM implementation of ReactiveX (Reactive Extensions): a library for composing asynchronous and event-based programs by using observable sequences.
• RxAndroid is a lightweight extension to RxJava that providers a Scheduler for Android’s Main Thread, as well as the ability to create a Scheduler that runs on any given Android Handler class.
• The two main classes are Observable and Subscriber.

You can use this class to realize a simple sectioned grid RecyclerView.Adapter without changing your code.

The RecyclerView has to use a GridLayoutManager.

This is a porting of the class SimpleSectionedListAdapter provided by Google

If you are looking for a sectioned list RecyclerView.Adapter you can take a look here

Unless specified otherwise, all of the below tinting applies to both Lollipop and pre-Lollipop using AppCompat v21. To use the support version of these attributes, remove the android namespace.  For instance, "android:colorControlNormal" becomes "colorControlNormal".  These attributes will be propagated to their corresponding attributes within the android namespace for devices running Lollipop.  Any exceptions to this will be noted by including the "android:" prefix.

All Clickable Views:
-----------
* ripple effect (Lollipop only) -- "colorControlHighlight"

Status Bar:
------------
* background (Lollipop only) - "colorPrimaryDark"

#Android and CI and Gradle (A How-To)

There are tech stacks in this world that make it dead simple to integrate a  <abbr title="Continuous Integration">CI</abbr> build system. <br>
The Android platform is not one of them. 

Although Gradle is getting better, it's still a bit non-deterministic, and some of the fixes you'll need will start to feel more like black magic than any sort of programming.

But fear not! It can be done! 

Before we embark on our journey, you'll need a few things to run locally:
