Study Notes
Electronic Devices
- Electronic devices are physical objects that use electronic circuits and systems to process information and perform tasks.
- Examples are smartphones, computers, tablets, televisions, digital cameras, smartwatches, and audio devices.
Smartphones
- Smartphones are mobile phones that go beyond basic calling and texting.
- They function like mini-computers that can connect to the internet, run apps, take photos, play music and videos.
- Examples of smartphones from various manufacturers are Apple iPhone, Samsung Galaxy series, Google Pixel phones, OnePlus phones, Xiaomi phones, and Huawei phones.
Operating Systems
- Operating systems (OS) are software that allows mobile devices to run applications and programs.
- Mobile OS provides an interface between the device's hardware components and software functions.
- Examples of mobile operating systems are Android, iOS, HarmonyOS, KaiOS, and Windows Phone
- Android works on Samsung, Google, OnePlus, and other devices.
- iOS works on iPhones and iPads.
- HarmonyOS works on Huawei smartphones, tablets, smartwatches, and other Huawei devices.
- KaiOS works on devices like Nokia, JioPhone, and other budget-friendly devices.
- Windows Phone (Windows 10 Mobile) works on Windows-based smartphones.
Mobile Apps (Mobile Applications)
- Mobile apps are software programs designed to run on mobile devices.
- Mobile apps are typically downloaded from app stores (like Apple's App Store or Google Play) and installed on the device.
- Mobile apps are categorized by whether they are web-based, native, hybrid, or cross-platform.
Mobile App Challenges
- Mobile apps face various challenges including diversity in system availability and users, hardware types, security concerns, battery usage, and functionality.
Mobile App Development Approaches
- Native apps are developed for specific platforms using platform-specific languages.
- Web-based apps are accessed via web browsers using web technologies.
- Hybrid apps combine web technologies within a native container.
- Cross-Platform apps use frameworks for code deployment across platforms.
Cross-App Platform Framework
- Cross-Platform App Development Frameworks allow developers to create mobile applications compatible with multiple operating systems (like iOS and Android).
- Developers can write code once and use it for different platforms, leading to faster, safer, and more efficient releases.
Top Cross-Platform App Frameworks
- Top Cross-Platform App Frameworks, each with their own advantages and disadvantages, include React Native, Flutter, Xamarin, Ionic, and Unity.
React Native
- React Native is developed by Facebook.
- It uses JavaScript and React to build native-like user interfaces.
- It's popular for its performance and ability to reuse components.
Flutter
- Flutter is developed by Google.
- It uses Dart programming language and provides a rich set of pre-designed widgets.
- It is known for its expressive UI and fast development cycle.
Xamarin
- Xamarin is developed by Microsoft.
- It uses C# and.NET framework.
- It offers native-like performance and access to native APIs.
Ionic
- Ionic is built on top of Angular and Apache Cordova.
- It uses web technologies (HTML, CSS, JavaScript).
- It is suitable for creating web-based mobile apps.
Unity
- Unity is primarily used for game development.
- It supports cross-platform development for mobile, desktop, and web.
- It uses C# for scripting.
Platforms and Environments
- A platform is the environment where software runs or is made.
- It includes both the hardware and the software that allow apps to work.
- Examples of platforms include Android, Blackberry, iOS, and Windows Phone.
Language and IDE
- Different platforms use specific languages and IDEs to build applications.
- Android applications are usually developed in Java, C, C++, or Kotlin using Android Studio.
- Blackberry applications are usually developed in Java using Blackberry JDE or Eclipse.
- iOS applications are usually developed in Objective-C or Swift using Xcode or AppCode.
- Windows Phone applications are usually developed in C#, VB, C, or C++ using Visual Studio.
