Program Android & iOS Apps easily

In the current era of digital technology 4.0, professions related to information technology are increasingly growing strongly and catching up with the general market.

In which Android and iOS app programming is becoming popular, if you do not grasp the information about app programming, it is a mistake on your part. But don’t worry, Sento App – professional app design according to your requirements will provide information through the following article to get useful information, ensuring to improve the efficiency of using mobile devices to the max.

1. What is app programming?

“Mobile application” or “application” (English: Mobile or app) is an application software designed to run on smart mobile devices: Smartphones, tablets and some other mobile devices. .

App programming is the use of programming languages ​​to write apps to develop applications to the best level to create utilities for the mobile devices you use. Among the two commonly used operating systems today are iOS and Android, being able to design a suitable mobile app will well meet the actual needs and demands of people. Among them, popular applications such as chat, games, dictionaries, reading stories, synthesizing stock information, gold prices, or accessing social networks, applications for businesses.

2. What are the benefits of mobile app programming?

Mobile app retains customers with convenience and versatility. Designing a mobile application that is useful, easy to use, versatile and has an impressive and creative interface will easily win the love and trust of customers. In particular, a good mobile application design also demonstrates professionalism and precision in the customer care process.

You can encourage users to talk about your business positively, with promotions and incentives specifically for those who download the app. Any company’s marketing campaign must be accurately communicated to target customers and guaranteed to be readable.

According to 2019 statistics, the number of people using Smartphone mobile devices is twice that of computers and laptops. The habit of using apps for work, study, entertainment, etc. is becoming increasingly stronger. Therefore, businesses can benefit directly from investing in this mobile app design.

With just a smartphone with an internet connection, customers can interact, buy and use your company’s services 24/7, at any time without time or geographical restrictions. or distance.

Increase interaction with customers

3. App programming languages 

If you want to develop mobile applications, the most basic thing is to know programming languages.

Using programming languages ​​will help renew the process of building mobile applications smoothly, meeting the requirements and descriptions of customers in all fields and all industries.

3.1. Android programming language

3.1.1. Java programming language

Java is an object-oriented programming language (OOP) and is based on classes.. Unlike most common programming languages, instead of compiling source code into machine code or interpreting source code at runtime, Java is designed to compile source code into bytecode, which will then be executed by the environment ( runtime environment) runs.

The outstanding advantage of using the Java language in building Android applications is that we can freely be creative to create the app as we wish.

However, creativity has certain limits, within each person’s own professional knowledge and understanding of this programming language. Therefore, before starting, consult the information and learn carefully to be more proactive and effective when using Java in mobile application programming.

3.1.2. Kotlin programming language

Kotlin  is a static programming language that runs on the Java virtual machine (JVM) and can be compiled to Java source code or using the LLVM compiler infrastructure.

Kotlin language is provided by JetBrains – a company from the Czech Republic specializing in developing ItelliJ IDEA. Currently, this language is officially supported by Google to meet the needs of each person in the process of writing apps according to actual requirements.

3.2.1. Swift programming language

Swift  is an object-oriented programming language for iOS and macOS, watchOS, tvOS, Linux, and z/OS development. introduced by Apple at the WWDC 2014 conference. Swift is expected to exist alongside Objective-C, the current programming language for Apple’s operating systems. Swift is designed to work with Apple’s Cocoa and Cocoa Touch frameworks, and much of the existing Objective-C code is written for Apple products.

Currently, Apple has added many useful and wonderful features to the Swift language, such as very simple syntax, effective programming error finding, etc. It is from those useful features that using Swift brings. The ability to complete applications effectively, meeting the goal of mobile app programming for the iOS operating system being carried out as desired.

3.2.2. Objective-C programming language

Objective-C is an object-oriented programming language often used to write applications for Mac OS X and iOS. Designed from the C language, adding the function call style of the Smalltalk language. Developed in the early 80s by NeXT company (Steve Jobs’s company when he retired from Apple) Objective-C (obj-C) extends from the C language so the properties and characteristics define the concept. C’s concepts are all there.

4. Notes when developing iOS – Android mobile applications

Take advantage of mobile device capabilities not available on PC:

For example, leveraging the camera to quickly capture an image or signature, using location services to narrow search suggestions, using sensors to reduce user and platform application effort.

Design apps, not applications:

The more complex and difficult part in an application is usage and navigation, especially in the context of “On-the-go” Smartphones, with frequently changing environments (Users can stand, sit, move moving, or the light intensity frequently changes).

Designing experience layers:

First-time users should feel something special and valuable as soon as they launch the app, followed by easily discovering the many benefits.

Effective features:

Mobile friendliness, with maximum mobile data, is what an app designer needs to ensure. Even if users use 3G, 4G,… data, they can use it easily and without encountering any unexpected problems or exceeding the allowed limit. With an app that does not take up too much data when running in the background, it can be optimized for all device models, making it easier to reach customers and attract more users.
