Study Notes

What is a Mobile Device?

A mobile device is a portable handheld computer that functions without being physically connected to a network and power source.
Mobile devices must be able to send and receive information wirelessly.
Examples include smartphones, tablets, laptops, smartwatches, e-readers, and handheld gaming consoles.

Mobile Device Components

Mobile devices consist of hardware, software, and a mobile system.
Mobile hardware includes the physical components of the device, such as the screen, processor, and battery.
Mobile software includes the operating system and applications that runon the device.
The mobile system refers to the software and hardware that work together to enable the device to function.

Mobile System Software

An operating system (OS) is designed specifically for mobile devices.
Mobile OSs are responsible for defining features and functions of the device, including keypads, application synchronization, and text messaging.
Mobile application software refers to programs designed to run on mobile devices.
Native mobile apps are designed for a specific platform (iOS, Android, Windows).
Web apps are responsive websites that adapt to mobile devices.
Hybrid mobile apps function through web browsers and are developed using HTML5.

Mobile Computing

Mobile computing refers to the use of mobile devices to access and transmit data wirelessly.
Key characteristics of mobile computing include user mobility, network mobility, device mobility, session mobility, service mobility, and host mobility.

Mobile Computing System

A mobile computing system involves clients or nodes connected through a wireless network.
These networks allow for anytime, anywhere computing.

Mobile Computing Principles

Portability : Devices should be physically portable and have sufficient processing power.
Connectivity : High level network availability is required with minimal lag/downtime.
Interactivity : Nodes must actively interact with each other.
Individuality : Mobile computing systems should adapt to individual needs and provide contextual information.

Mobile Computing Advantages

Location Flexibility
Saves Time
Enhanced Productivity
Ease of Research
Entertainment : Streaming video and audio on the go.

Mobile Application Development (MAD) Factors

Platforms and Device Compatibility: Ensure app runs on target platforms and devices seamlessly.
Screen Size: Design for different screen sizes (smartphones vs tablets).
Screen Density: Optimize graphics and text clarity for varying screen resolutions.
User Interaction: Smooth and intuitive interface design.
Phone Function Integration: Leverage device features like camera, GPS, etc.
Resource Management: Efficient resource use for battery life and performance.

Frameworks

A framework is a software skeleton that provides tools, libraries, and other components.
Xamarin: Enables cross-platform native apps using C#.
React Native, Ionic, Flutter: Popular cross-platform frameworks.
JDK (Java Development Kit): Software development kit for Java applications.
JRE (Java Runtime Environment): Required to run Java applications.
JVM (Java Virtual Machine): Enables computers to run Java programs.

Bytecode

Bytecode is machine-readable code that is interpreted into binary code by a computer's processor.
