Comparing Windows Phone and Android Navigation


Windows Phone apps are a collection of pages. Like Android, the user navigates through pages using controls such as buttons and links. Like Android, all Windows Phones have a Back button on them. On Windows Phone the back button behaves much like the back button in the browser allowing the user to navigate between pages of an app or even across apps. For example, consider that the user clicked a link in the email application to launch the browser. With the Back button, the user would return back to the email application. The Back button also closes menus and dialogs. As a developer, you should consider what the Back button means to your user and plan to override it appropriately. For example, you may decide to pause a game by using the Back button on the Phone.

The other two hardware buttons on the Windows phone, namely, Search and Home, have fixed behaviors. The Home button takes the user to the Windows phone main page, much like Android. Unlike Android where search button provides context sensitive search, the Windows Phone search button performs a web search using Bing.



Windows Phone Frame and Page Structure


Each Windows Phone application has a single frame. It includes areas for:

A page where application content is rendered. This is the content where controls or graphics are rendered.

A reserved space for the status bar and application bar. It also exposes certain properties, such as orientation, to the application.

Status Bar and Application Bar


On Windows Phone, the status bar includes indicators for a variety of system-level status information items such as connection status. The application bar includes the area for the most common application menus, which may include various data views or tasks. The application can manipulate the status bar to change its visibility, opacity or the color. The application can use it to show progress.

Page Structure of a Windows Phone Application


The following diagram shows the structure of a typical Windows Phone data-bound application, which resembles the structure of a navigation-based Android application.

When the user first starts the application, he or she is presented with a splash screen, designed to welcome the user, as well as to create the perception of a fast response. Splash screens are usually an image file of the size of the display.

Usually the application starts with the home page, the main navigation page, with links for search, and other page controls. Consider an application that shows information about baseball teams and their players. The primary content page, marked as the widgets page in the above diagram, will have the content of interest, for example, a list of all baseball teams. However, depending on requirements, the home page can also be the primary content page.

The user can click on one of the team links to visit the team details page (“widget details page”) which can provide multiple views. The page may employ a pivot control or a panorama to display different views such as the team summary and the list of all players (“list of gadgets”) from that team. Selecting one of the baseball players will take the user to the page with player statistics (“Gadget Details page”). Such a page may use controls such as textblocks, multi-scale images, or other multimedia using a MediaElement control.

Users may also use the search page to search and directly access the team page (“widget details”) or the player page (“gadget details”)

Application Templates


Visual Studio Express 2012 for Windows Phone provides a variety of templates for developing Windows Phone 8 applications. Visual Studio templates create the appropriate structure of the application automatically.

You can choose the Windows Phone application template to either create an application with functionality similar to the view-based or the window-based Android application type.

Summary


In this chapter we looked at the similarities between the application design goals of the Android and Windows Phone 8 platforms. When you plan your Windows Phone 8 application, you will be able to leverage your existing work on Android applications.

Revisit the application interface design to make sure you are taking advantage of the Windows Phone controls and Windows Phone design and interface guidelines. You will find that the Windows Phone 8 offers a large library of controls and gestures that have close counterparts on Android. This chapter also showed you the use of innovative controls like Panorama and explored the use of live tiles in building an engaging Windows Phone 8 experience.
