Discussion 4

35. App development for mobile devices is both simular and different from development for desktop platforms. Navigation within an app has some of these similarities and differences; different functionality is provided on different screens. App designers have to provide both the capacity to switch between those screens and make it easy and relatively obvious for users to do so when they want or need the functionality provided by those screens. So, yes – screen design is both similar to and different from traditional UI design. However, the objects available for design differ in both form and function. The amount of screen real estate is much more limited and the amount of real estate available changes among devices that can use your app. The skillset used in traditional development is useful, however, Android app development requires additional skills and knowledge of Android fundamentals.

The phrase “navigation” refers to processes that allow users to move around different areas in your app’s information as well as entering and leave it. If you’re using a simple button-click navigation pattern or something more intricate such as app bars or the navigation drawer in Android Jetpack, the Navigation feature will help you implement it. It is possible to begin incorporating the Navigation component after you’ve made the switch to a fragment-based layout (Megalingam and. 2019). To begin, you must update your project’s dependencies to be compatible with the most recent Version of the Navigation library, following the instructions provided in. It stores your configuration of navigation for your app in a resource file in the form of graphs, as is the way that views are saved. Create a brand new resource directory, called navigation which is where you can store your graph of navigation and utilize visually-based editors for making modifications to the navigation of your app outside within the codebase. You can add your graph using right click in this folder and selecting New navigation resource file. If a user is using your application, the Navigation component will use an activity as the host and then insert various pieces within that activity (Smyth 2020). Setting up the NavHost in the application hosting this graph is an essential step to begin the visual design for your application’s navigation. Cont…
