Create A Couchbase Lite Todo List With Native Android

By now, if you’ve been keeping up with my tutorials, you can probably put two-and-two together and determine that I’m really trying to get into the NoSQL world. Up until now I’ve brushed upon Google Firebase, Facebook Parse, and Apache CouchDB, most of which I’ve done some kind of todo list type application. Now of course, many of my previous tutorials were based on hybrid app development instead of native.

This time we’re going to take a look at Couchbase’s version of NoSQL in a mobile Android application. In particular a native Android application.

Sort An Integer Array With the Quicksort Algorithm And Java

Circling back to data structures and algorithms, we’re now going to take a look at the efficient sorting algorithm known as Quicksort.

Quicksort via Wikipedia:

Sometimes called partition-exchange sort, is an efficient sorting algorithm, serving as a systematic method for placing the elements of an array in order.

The idea behind Quicksort is to take a large array of values and divide it into two smaller arrays, doing this recursively, and swapping elements.

This is one of the fundamental algorithms you’ll learn in any computer science course. It is also a very good question that could be asked in a job interview for an engineering type position. I’m going to help you through it using Java.

Using Gradle In Your Command Line Android Project

I’ve been developing mobile Android applications since 2011 and up until now I’ve been using nothing but Apache Ant for building them.

Now you’re probably like, it is 2015, why aren’t you using Gradle like the rest of the world? Well, I like Apache Ant, and I had no real reason to switch. However, I’ve decided this is the year I jump ship.

If you’re like me, a no IDE rebel coming from an Apache Ant world for Android development, this might help you out in making the switch to Gradle.

Adding Background Images To Ionic Framework Apps

I started working on an app and decided it was time to step up my design game. Usually my apps suffer from looking plain or dated even though they have some insanely awesome functionality (ex: OTP Safe). However, after looking at many other apps, I came to the conclusion that an app can look more attractive just by including a logo or some other kind of branding images.

The tricky part here is, how might you add images to your Ionic Framework application and have them look good across devices with multiple screen densities? After doing some research I found that this could easily be accomplished by using background images created with CSS.

Use Parse Core In Your Ionic Framework Mobile Apps

It is time I talk about another cloud data storage option for Ionic Framework. Previously I had shown how to use the Dropbox Datastore API, Firebase, and PouchDB to store information remotely.

This time I am going to discuss how to store data using Parse, a Facebook company, and retrieve data from the cloud.

Various Graph Search Algorithms Using Java

If you’ve been keeping up with my blog, I’ve made a topic regarding Binary Search Trees, but another very important topic in computer science and software engineering is in regards to Graphs.

Graphs via Wikipedia:

A graph data structure consists of a finite (and possibly mutable) set of nodes or vertices, together with a set of ordered pairs of these nodes (or, in some cases, a set of unordered pairs). These pairs are known as edges or arcs.

When interviewing for a new programming or software engineering position, it is incredibly likely that you are asked a question on this topic. Because of this, I figured it would be a good idea to go over a few of the Graph search algorithms.

Determine If A Number Is Prime Using JavaScript

Continuing on the topic of interview questions for programming and software engineering type positions, I thought I’d brush up on a popular one.

Although I have never personally been asked about this, other people have told me that they’ve been asked to determine if a number is prime or to print out all prime numbers up to a certain number.
