How to Become a Android / iOS Application Developer

Degree in Computer Science: 

• A degree in computer science is not strictly necessary. Many companies will prefer you have at least a bachelor's degree in computer science if they are going to hire you on as a developer.

Use online development programs. 

• Apple offers the iOS Dev Center. In the center, you can view tutorials and videos to help you begin learn coding. Android has a similar site, Android Developers Training. However, you don't need to rely on just the official streams. Many websites across the web offer free classes and tutorials, though you can also find for-pay classes if you want to take it to the next level.
• One example of a place where you can learn coding is W3Schools, a well-known website for learning coding. It has a section on JQuery Mobile, which you can use to create mobile apps. This coding system is based in CSS3 and HTML5.
• You can also try places that offer free online courses on a wide variety of subjects, such as Udacity, treehouse, edX or Coursera.

Develop your own app. 

• If you prefer to be hired on by a company, some great practice in the meantime is to develop your own app. It doesn't really matter what it is as long as it is useful or fun. Then, when you are searching for a job, you have something to prove your work.

Don't forget to test it for bugs. 

• New apps always have bugs, so play-test your app. Have your friends test it, too, to see where the bugs are so that you can fix them. It also teaches you what works and what doesn't work in an app.
