Questions and Answers

Explain the difference between imperative UI and declarative UI in the context of Android app development.

Imperative UI involves specifying detailed instructions for creating the user interface, while declarative UI involves specifying the desired outcome and letting the system handle the implementation details.

What are the advantages and disadvantages of developing a web app for mobile devices?

Advantages: responsive to any screen size, can be added to home screen, works on any platform. Disadvantages: slower performance, limited access to device's features, not available from app stores.

Describe the key characteristics and considerations of hybrid-web app development.

Key characteristics: blend of mobile-optimized UI components with native modules, lower development costs, multiplatform. Considerations: slower performance for performance-intensive apps, highly dependent on libraries and frameworks.

Explain the role of WebView in hybrid-web app development and its impact on UI rendering.

<p>WebView is responsible for UI rendering in hybrid-web apps, and it impacts performance due to running the app inside a WebView.</p> Signup and view all the answers

What are the main differences between native app development and cross-platform app development?

<p>Native app development involves creating separate codebases for different platforms, while cross-platform app development allows writing once and running anywhere with a single codebase.</p> Signup and view all the answers

What are the key reasons for learning app development in the context of the ubiquitous use of smart devices?

<p>The key reasons for learning app development in the context of the ubiquitous use of smart devices include the large market opportunity for businesses and developers, the integration of apps into daily life for work, play, and study, and the representation and understanding of the user that mobile devices provide, as they are connected to the outside world and intimately 'know' the user.</p> Signup and view all the answers

What are the advantages and limitations of developing a web app for mobile devices?

<p>Advantages: Responsive web apps can adapt to any screen size, can be added to the home screen, and can work on any platform. Limitations: They have slower performance as they run inside a WebView, provide limited access to device's features, and are not available from the app stores.</p> Signup and view all the answers

What are the main characteristics and considerations of hybrid-web app development?

<p>Hybrid-web apps blend mobile-optimized UI components written using HTML, CSS, and JavaScript with native modules or bridge plugins for accessing device features. They offer lower development costs, multiplatform capability, and can be downloaded from app stores. However, they have slower performance, are not suitable for performance-intensive apps, and are highly dependent on libraries and frameworks.</p> Signup and view all the answers

What is the role of a WebView in hybrid-web app development, and how does it impact UI rendering?

<p>In hybrid-web app development, the app runs inside a WebView responsible for UI rendering. The WebView allows the app to access platform services via a bridge. This impacts UI rendering as it affects the performance and access to hardware and sensors.</p> Signup and view all the answers

What are the differences between native app development and cross-platform app development?

<p>Native app development involves building apps specifically for a single platform, providing high performance and full access to device features. Cross-platform app development involves building apps that can run on multiple platforms, offering lower development costs and a single codebase. However, cross-platform apps may have slower performance and are highly dependent on frameworks and libraries.</p> Signup and view all the answers
