When looking at the worldwide statistics for sales, Android has a clear lead over iOS in terms of market share. Statcounter reports that over the January 2018 to January 2019 period Android made up a massive 74.45% of the sector, with iOS way back on 22.85%. The remaining 2% were comprised of 1.1% for KaiOS (a web-based operating system to enhance feature phones), 0.3% Windows (yes, really), 0.28% Samsung, and 0.41% unknown.

Seeing the demand for Android development in the market, more developers are needed as well. As a result, more and more developers, as well as tech enthusiasts, are wondering what is needed to start a career as an Android app developer.


When it comes to Android software development, there are complex skill-sets employers are looking for in a candidate.

Android is quite demanding for developers. While there are tools that allow you to not develop from scratch, there’s still a need to write a ton of custom code as well as to know a few programming languages.

Java is a primary programming language Android developer have to use. While hiring a junior developer, employers will be examining the knowledge of the following:

● Object-oriented concepts;
● Variables;
● Static methods;
● Inheritance;
● Loops;
● Lists.

Also, when aiming for Android development, make sure you know how to read documentation here, all the updates on Java SDK are posted.

The Android SDK the first tool needed to start development regardless of whether it’s custom or tool-based such as Android Studio, downloading the Android SDK is where a developer has to start.

It goes without saying, a strong command of the SDK is necessary if you want to know how to make an Android app. Here are the main concepts you should be focused on learning:

● Views and layouts;
● User input;
● Lifecycles and activities;
● Collection views;
● Storing data.

There are dozens of useful sources to check out while learning the Android SDK. You can look courses up at EdX or Coursera, and don’t forget to surf Stack Overflow as well.

Working with APIs: Working with data is a crucial component of any software development, Android programming included. That’s why most companies have network-based applications in mind. This presumes that a developer will get the hang of either proprietary or third-party APIs.

The two main types of APIs are the following ones:

● JSON/REST – these are the new black in the industry and a must-have for a developer to learn;
● XML/SOAP – not as popular these days but is still required by companies.

Both types have relatively similar working principles, with nothing but a few differences in data parsing and request.

Back-end Knowing how to write the back-end code is rather rare among junior developers. However, it’s highly appreciated among employers and will help newcomers to jump-start their careers.

Note, that back-end consists mainly of a set of technologies (.NET, Ruby-on-Rails, Django, Java etc.). A developer should not try to learn all of those at once rather focus on tackling them one-by-one.

A few main aspects to focus on while learning a programming language for back-end editing are those of the language syntax and the system architecture. Fortunately, most programming concepts easy to translate between languages the more you know, the easier the next one becomes to learn.

Having to work in teams is challenging for developers especially due to the fact that, among from those with solid experience of coding, there are managers or clients that have little to no idea about what Android development is from the tech point of view.

Being able to collaborate with people who have different backgrounds is crucial even for junior Android developers. Moreover, thinking about how to hire a developer, companies started paying attention to the way a developer can work as a part of an international team whether he/she can adjust to video calls in different time zones, understand a person who speaks little English, etc.

Android app development is growing at an impressive pace these days. More businesses are discovering the power of mobile technologies and are eager to harness it. That’s why Android developers are in demand in the market at the moment. Starting a career in Android development is time-consuming and challenging. However, in the long run, it’s a worthwhile field to explore, with dozens of job openings available.
