Introduction to Mobile Devices and Class Policies

A portable handheld computer designed to connect to the internet. It's easy to use and can be taken anywhere.

Creating software applications that run on smartphones and tablets. These apps can be designed for different operating systems like Android or iOS.

A type of mobile device with a touchscreen interface used primarily for reading e-books.

A type of mobile device with advanced functionality and a touchscreen interface, used for communication, internet browsing, and various applications.

A type of mobile device with a larger touchscreen interface primarily used for entertainment, productivity and browsing.

Attendance is mandatory and a minimum of 80% attendance is required to be eligible for the final exam.

The course grade is based on the total points earned from assignments, quizzes, midterms and final exams.

Communication is important! Reach out to the instructor via email if you have any issues or concerns.

Mobile apps built specifically for a specific operating system, such as Android or iOS, using platform-specific languages. They offer full device functionality and are installed directly from app stores.

Cross-platform apps created using web technologies like HTML, CSS, and JavaScript. They are essentially web apps packaged as native apps, offering a balance between web and native features.

Mobile applications accessed through web browsers. They don't require installation, but their functionality is limited by browser capabilities.

Google's mobile operating system, known for its openness and flexibility. It's written in Java, Kotlin, and C++ and powers a wide range of devices.

Apple's proprietary operating system for iPhones and iPads. It's known for its smooth performance, security, and strict app store guidelines.

A set of mobile operating systems that have either been largely phased out or are no longer popular, but their influence on mobile development remains significant.

An open-source mobile operating system developed by Google. It's used across various devices, including smartphones and tablets. Its accessibility and versatility have contributed to its widespread adoption.

The initiative formed by Google to develop and promote Android as an open-source mobile operating system. It brought together various hardware, software, and telecom companies to create a collaborative ecosystem for mobile innovation.

Android is a mobile operating system that allows for open development and application installation from various sources. It facilitates inter-app communication, providing more flexibility.

Android's diverse versions and upgrade delays across manufacturers can cause compatibility issues for app developers.

iOS offers a streamlined upgrade experience, ensuring that a majority of users are on the latest version. This provides consistency for developers.

Android allows developers to publish apps to Google Play for a one-time fee, while iOS requires an annual subscription to the developer program.

iOS prioritizes a closed ecosystem, limiting communication between apps and automatically rejecting private APIs.

Android development can be done on any platform, while iOS development necessitates a Mac computer.

The process of signing apps on iOS is more complex compared to Android, requiring adherence to strict guidelines.

Google Play Store and Apple App Store are the most popular marketplaces where users can download and install mobile applications.

Offering free apps with ads, freemium apps with in-app purchases, paid apps, and subscription services, each has its own pros and cons in terms of revenue generation and user engagement.

A structured process that involves stages like defining the app idea, designing the user interface, writing the code, testing the app, releasing it, and maintaining it over time.

The process of choosing the right language for your mobile app development depends on factors like the platform (Android or iOS), the desired development speed, and the app's features.

Android Studio and Xcode are the official development environments for Android and iOS respectively. React Native and Flutter are popular cross-platform frameworks that simplify building apps for both platforms.

A software development approach that separates concerns into distinct layers, enabling developers to write, test, and maintain code more efficiently.

The principle that dictates separating different parts of an application based on their purpose or responsibility. This makes the codebase more maintainable and easier to understand.

The ability to easily test individual components of an application without depending on other parts. Clean architecture promotes testability by allowing developers to write unit tests for each layer independently.

The capability of an application to easily handle changes and growth. Clean architecture promotes scalability by allowing developers to add new features or modify existing ones without impacting other parts of the system.

A common issue with clean architecture is that it can add complexity to the project, as it involves multiple layers and a more organized code structure, which can make it harder to understand and maintain.

A software design pattern that divides an app's logic into three distinct parts: Model (data and business logic), View (user interface), and Controller (application logic).

It manages the data and business logic of the app, responsible for data storage and updates, independent of how it's displayed.

It represents the user interface (UI) and displays data from the Model. It handles the visual representation of the app's content.

The intermediary between the Model and View, processing user input and translating it into actions that update the data or the UI. It controls the flow of data.

A key advantage of MVC is that it promotes separating different parts of the application, making it easier to maintain and test.

MVC can be complex as it involves multiple components that need to work together. It can also lead to tight coupling between the View and Controller.

In an e-commerce app, the Model holds product information, the View displays the products and the cart, and the Controller handles adding items to the cart or processing payments.

It helps to manage the complexity of applications by promoting modularity and separating concerns, leading to more maintainable and manageable code.
