In what Dan Pink calls the emerging Conceptual Age, we’re all going to be...
The ability to develop apps for Android 5 Lollipop is an extremely hot skill to know right now. For the first time, it is starting to overtake Apple’s iOS as the most lucrative mobile platform to develop apps for. Given the beautiful new Materials Design framework in Lollipop, now is an excellent time to learn Android development.
In terms of marketshare, Android is absolutely clobbering iOS with a whopping 85% of the global market in 2014. This growth is also accelerating as more people globally plug into the Internet for the first time. A mind boggling 1.3 million new Android devices are activated each day and the number of Android devices in the world now numbers in the billions.
With such astounding growth, there is naturally a shortage of capable Android developers. In the past 5 years, the majority of developers have favoured Apple’s iOS. This was because there was less fragmentation in the ecosystem and Apple users have traditionally spent much larger sums of money on apps.
Fortunately for Android app developers, Google has put enormous resources in the last year into improving the Android user experience (the new Materials Design in Android 5 Lollipop rivals the slickness of iOS 8) and improving the quality of the Google Play app and content marketplace.
The growth and mobile operating system dominance of Android will continue for the foreseeable future. Android app development is currently the #4 most sought-after digital skill on Indeed, which means there are plenty of opportunity for freelance Android app developers. The money is also very good, with an experience Android app developers making an average salary of $100,000 a year in the US.
How To Start Learning Android Development Online:
The fastest way to learn Android development is online. Preferably you already you already have some experience with computer programming languages like Java, C or C++. If not, the learning curve will be much steeper but learning Android development is do-able with a lot of focus and determination (although, you may want to take a more introductory computer science courses first to establish the fundamentals).
Android apps are written using the Java programming language. It is helpful to have a basic knowledge of Java programming before beginning the courses below but a few of the courses are specifically geared toward absolute beginners.
Here’s how to get started:
1. Download and install the free Android SDK (Software Development Kit), Android’s open-source IDE (Integrated Development Environment) Eclipse and the Google-supported ADT Plugin is also recommended for Eclipse. The combination of these three tools will give you the full integrated development environment you require to start building Android apps.
2. Create your first “Hello World” app with this easy-to-follow tutorial for beginners from Google.
3. Take an Android development course online. The best way to learn is by diving in and hacking together some basic apps. This help you get familiar with the Android API (Application Programming Interface) and the possibilities of Android app development.
4. You can access more Android development tools by signing up as an Android Developer on Google Play (there’s a one-time $25 registration fee).
5. Subscribe and follow the Google Android Developers blog to learn about new developments in the Android app ecosystem.
6. Another essential resource is Google’s Training Resources For Android App Developers. I also recommend reviewing their new introduction to creating apps with Material Design.
Google has created an Android Developer portal where you can get everything you need to start creating your first Android app. On this website, you can download the Android Software Development Kit (SDK), take Android video classes, read their blog and access extensive Android Development resources.
Free Android Development Courses:
These are the most up-to-date resources that I have found for learning Android app development online. Updated for the latest version of Android 5 Lollipop.
1. Programming Mobile Applications for Android Handheld Systems (University of Maryland)
Part of a larger course on Mobile Cloud Computing with Android 4.4 KitKat. This course focuses on designing and building user-facing applications. The next part of this course will begin in June 2014 on Coursera so join this free course now. Free.
2. Building Mobile Applications with iOS, Android and HTML5 (Harvard University)
An excellent course on mobile development from Spring 2012 that covers iOS development, Android Development and 5 lectures on HTML5 mobile development. This course has assignments and video lectures that will help you build your first mobile apps for either Android or the iPhone or iPad. You can take this course on the official website or through iTunes University. It’s a little dated but still relevant. Free.
3. Creative, Serious and Playful Science of Android Apps (Coursera)
An introductory course directed at people with no previous programming experience. It teaches you fundamental computer science principles and how they apply to building Android smartphone and tablet apps. By the end of the course, you will have created your first Android app using Java and Google’s standard software development tools. Unfortunately, the next session of this 5-week long MOOC has yet to be announced. Free.
4. Android 4 Video Bootcamp (Merkana)
The full screencasts from a 5-day on Android Development for Android 4.0 (Ice Cream Sandwich). The course includes a good introductory slide presentation and 20 relatively easy-to-follow video tutorials.
5. Creative Programming for Digital Media & Mobile Apps (Coursera)
Okay, I don’t think this online course focusing on Android Development specifically, but it looks really useful because it teaches beginners how to code your own creative projects. You also learn the technical skills to write software that uses sophisticated graphics and audio with the focus on creating mobile applications that run on smartphones and tablets.
Premium Android App Development Courses:
You can only go so far with free resources. These courses cost a little bit of money but they are taught by Android development experts and will get you going much faster. Also, they are updated for the new requirements of Android 5 Lollipop.
Go from a beginner to a proficient Android developer in just 5 weeks of hard work. This is the #1 Android development course on Udemy and the instructor is constantly adding valuable new information to ensure your skills are kept up-to-date. Given that Android development boot camps cost upwards of $7000-$10000, this course is a bargain if you’re a self-directed learner. $199
Android Video Tutorials:
A collection of 35 (and counting) excellent videos that teaches you how to create Android Apps geared towards absolute beginners.
- App Inventor For Android (MIT)
If you have no programming knowledge and you still want to try your hand at creating an Android app, then MIT’s App Inventor is designed for you.

Learn the basics of the Java programming language in an hour if you’re completely new to the programming language.
Excellent resources from experience Android developer, trainer and author Lars Vogel.
Mobile Development Frameworks:
There are 100s of Android development frameworks that can save you a huge chunk of time and make it easier to build basic Android apps.
Essential Android Development Resources:
