Big 3 in mobile operating system

The mobile market is a delicious piece of cake which draws the great attention of many businessmen, thus introducing a variety of different operating systems. However, when it comes to the big 3 in mobile operating system,  it is a must to mention Android, iOS and Windows phone.

The first to mention is Android with the "hegemony" of over 70% of the market shares. This leads to the great need to recruit android application programmers. iOS ranks second with 20%, but it is stated that iOS revenue is higher than that of Android due to higher percentage of users willing to pay for paid apps. Similarly for a programmer, in spite of the low demand for recruitment, they are offered with more attractive salary. The last one is Windows phone. Although it used to be listed in the top 3 but this operating system is quite inferior to the other two brothers. There is a low demand for recruiting a Window Phone programmer. It might be due to the poor applications of this operating system.

Application programming languages
Java is the programming language used in Android operating system. Those who have knowledge of this language can easily switch to Android application programming. XML might be also required to design the interface. Additionally, this is one of the most popular software programming languages today. Therefore, anyone should have gain some knowledge about this basic language.

Unlike Android, in order to program IOS applications, you need to access it via virtual machines or Macs running MacOS. Objective-C is used to program applications on this operating system. This is a versatile and object-oriented programming language. When compared to Java or C, it's quite complex. However, thanks to the available tools provided by Apple, it is not too difficult to build a practical application or use objective-C. However, iOS exercises a much stricter control over the applications than Android does.

The Windows Phone application is written in C# and XAML. So the programmers in this array can give it a try with Windows Phone. However, the recruitment market for this operating system is not really active because it somehow fails to attract programmer in spite of the fact that the competitiveness in this field is not as tough as in iOS or Android. Sadly, the operating system was declared "dead" in October 2017, after Microsoft announced that it would not develop new features or new hardware for the Windows Mobile platform.



Where to learn application programming?

After clarifying the goal of pursuing application programming career; acknowledging what to learn, ones might wonder where to learn? This is probably the most common question posed by beginners. There are many options when it comes to learning application programming, but the two most common ones are learning at a training center and learning at a company.

Nowadays, there are quite a few centers offering application programming courses, you can easily google and find some famous names such as Niit, Aptech, Devmaster, etc. Depending on the conditions and personal needs, you can choose a center yourself. However, it is strongly recommended that you ask for advice from experienced people and make a research based on the review of those who have learned in that institution to have an objective view on the quality of teaching and learning of each center.

Studying at a company in the form of vocational training or extra training is also a good recommendation. Vocational training in the company gives you more practical experience and (in my opinion) more values than a certificate issued by a training center when applying for a job. Some companies such as TMA Solutions offer programming courses in general and application programming in particular. After the training course, you are given the great opportunity to work for that company. Perhaps this is why training courses at a company attract so  many fresh IT graduates.
Windowphone, iOS, Android are all popular operating systems. However, in my opinion, Android is the most commonly used one, so where could I take the course or learn more about this operating system?
