3. Self-taught basic mobile application programming

3.1 Equipping with foundational application programming knowledge

Currently, smartphone devices run on two central operating systems, Android and iOS. The first thing that learners of mobile application programming need to do is choose a platform to develop on.

Learn the background information of the two operating systems.

Equip with basic knowledge of mobile programming languages ​​​​to write applications.

3.2 Android Application Programming Language

To write Android applications, there are two main languages ​​you need to know: Java programming language and Kotlin programming language.

Java is the most commonly used Android application programming language today. With a large user community, Java language users will receive excellent support and advice from those before. Using Java programming language helps programmers freely write Android apps as they please. The programmer's expertise limits this creativity. So, take the initiative to learn this language thoroughly to write handy Android apps.

Jetbrains developed the Kotlin language. Kotlin's primary function is to help overcome problems encountered when writing Android apps in Java. Kotlin language is considered to make Android apps quite simple. Therefore, when programming, you will not have to face too long and complicated lines of code. This helps programmers focus on the critical issue instead of wasting time processing statements.

To write Android apps at their best, we recommend learning both languages. Combining and exploiting the advantages of two languages ​​will help programmers perfect the ideal mobile app design language and achieve high results.

3.3 IOS application programming language

To program iOS, programmers need to know the following 2 languages: The Swift Programming Language and Objective-C programming language

The Swift programming language was released in 2014 and is the most trusted today. Swift is used in an open-source, practical approach and is preferred by many famous mobile manufacturers. Swift is also the language of choice for popular startups on the iOS platform for individuals.

Recently, IOS has added many helpful support features for Swift language, such as simple syntax, efficient error-finding, etc. These features provide efficient application completion and design. Perfect mobile app design for the iOS operating system.

The Objective-C programming language is considered the premise for the first development of the iOS operating system. Although Swift language is increasingly used today, Objective-C is still important and trusted in many projects.

The use of these two languages ​​helps the iOS programming process be more efficient.

4. Simple Mobile App Design Cycle
