The Android Honeycomb User Features Developers Need to Know
Developers sometimes become overly focused on the Android SDK features available in a new release and overlook the new user features made available at the same time. Understanding these user features is important for numerous reasons. Not only do these features directly affect your application's audience, but they entice new types of users to the platform and often improve upon existing features as well.
In this article, we discuss some of the hottest user features in the latest version(s) of the Honeycomb platform (3.0 and 3.1 thus far) and why developers should know about them.
Android Honeycomb: There's Still Time to Optimize Your Apps
As of June 1, 2011, only 0.6% of the Android devices accessing the Android Market were running Android 3.0 or higher. This means that despite the fact that Android 3.0 has been out for a couple of months now, developers have not missed the boat. You've still got time to look into the unique platform features available in API Levels 11 and 12, and incorporate them into your apps.
There's some question as to whether existing devices will be upgraded to Honeycomb, or skip straight to Ice Cream Sandwich in the fall. The point here is that Honeycomb is not a divergence in the platform. It's a pretty safe bet that the powerful features of Honeycomb will be rolled into Ice Cream Sandwich. So, incorporate new Android 3.0 features into your apps now, before the features go mainstream. That way, you will gain an edge on lazy competitors who simply ensure their legacy applications don't crash on new platform versions. Don't forget that the compatibility library enables developers to leverage features introduced in Honeycomb onto legacy devices as far back as Android 1.6.
Android Honeycomb: Not Just for Tablets
Although many of the user and developer features of Android 3.0 and Android 3.1 are targeted at making the platform tablet-friendly, do not mistake Honeycomb and its changes as a release solely for tablet devices. It's not. Many of the developer features of Honeycomb, like fragments, action bars, a new animation framework, and improved hardware acceleration and graphics APIs, can be leveraged by all applications. If you've traditionally developed smartphone apps and plan to target a broad range of Android devices in the future, you should consider Honeycomb features to help "future-proof" your apps.
Android 3.0's Hottest User Features
Android 3.0 introduced a lot of what we like to call "chrome": pretty, smooth, feature-full UI components. Much of the UI overhaul targets efficiency and usability--things critics have claimed the Android platform lacks compared to some of its more established competitors.
Let's explore some of Honeycomb's hottest user features, from the view of the developer.
- Instead of a static title bar, there is now an Action Bar at the top of the screen, which identifies the app. Each application can customize the Action Bar for its own purposes. The Action Bar can be used for in-app navigation and provides a launch point for contextual menus.
- Some of the newest Honeycomb devices do not have the physical hardware buttons for things like Home, Back, Menu and Search. Instead, Back and Home are integrated into the UI in what is called the System Bar; Menu is moved up to the Action Bar (but only when appropriate). A dedicated search button is no longer available, though Search can be added to the Action Bar as well.
- In terms of input, there's a new system-wide clipboard, which enables users to copy and paste text content. Check out the Clipboard Framework for more info.
- Users are already familiar with drag-and-drop operations on their Home Screen. Now apps can implement similar features using the new Drag and Drop Framework.
- The default software keyboard has been redesigned for improved user input. Several new keys have been added. If you were using special IMEs to provide features above and beyond the default software keyboard in your apps, it's a good time to review the built-in options again.
