In this article, I will give an introduction on how to develop Android apps. I will not get into many technical details but rather give an overview of the approaches you should consider before you get started.
Smartphones are taking the World by storm. In may 2012 a news item appeared which stated that in Europe, more than 50% of all new mobile phones sold were smartphones. In 2011 the worldwide sales figures of Android phones exceeded those of the iPhone, the phone that started the “smartphone revolution”.
With the growing number of Android phones, the number of available apps (small programs designed to work on these devices) has also grown explosively. In addition to mobile phones, other devices such as tablet computers that run on the Android operating system are also gaining popularity. The consequence of all this is that there is a growing need for Android apps.
The Google Play Store (formerly Android Market) is growing at an enormous rate: there are now over 500,000 apps available. These are very diverse: utility apps such as text messengers, task managers and email clients but also a host of games. The most popular apps are being downloaded millions of times. Other interesting categories are apps that enhance businesses. Examples of these are apps that enable customers to purchase products right from their mobile phone or apps that provide the location of a company branch in the vicinity of the user.
The increasing popularity of mobile apps gives rise to many interesting business opportunities. This trend is unlikely to change any time soon and established business around the world are acknowledging this fact. Not only have many businesses produced mobile apps to grow their revenue or enhance their image. The rise of mobile apps appears to be changing the way businesses and consumers think about software. A telling example comes from Microsoft: the new Windows 8 operating system has a “mobile look and feel” and the software programs in the system are now referred to as “apps”.
So, if you want to learn how to develop Android apps where should you start? It depends on your previous experience (if any) and the amount of time and money you are willing to spend.
The most obvious route is doing all the programming yourself. To do this you need knowledge of the Java programming language and the Android Software Development Kit. If you have never programmed before, you will have to learn a lot about subjects such as object oriented programming and working with the necessary developer tools. This is the long, hard road to becoming an app developer… however, if you succeed at making your first few apps, it can be extremely satisfying and you will have gained a lot of useful knowledge!
