Android OS 4.0 Ice Cream Sandwich
Android 4.0 (Ice Cream Sandwich) is the latest version of the Android platform for phones, tablets, and more. It builds on the things people love most about Android — easy multitasking, rich notifications, customizable home screens, resizable widgets, and deep interactivity — and adds powerful new ways of communicating and sharing.
Simple, Beautiful, Useful
Refined, evolved UI
Focused on bringing the power of Android to the surface, Android 4.0 makes common actions more visible and lets you navigate with simple, intuitive gestures. Refined animations and feedback throughout the system make interactions engaging and interesting. An entirely new typeface optimized for high-resolution screens improves readability and brings a polished, modern feel to the user interface. Virtual buttons in the System Bar let you navigate instantly to Back, Home, and Recent Apps. The System Bar and virtual buttons are present across all apps, but can be dimmed by applications for full-screen viewing. You can access each application’s contextual options in the Action Bar, displayed at the top (and sometimes also at the bottom) of the screen.
Multitasking is a key strength of Android and it’s made even easier and more visual on Android 4.0. The Recent Apps button lets you jump instantly from one task to another using the list in the System Bar. The list pops up to show thumbnail images of apps used recently — tapping a thumbnail switches to the app.
- The Recent Apps list makes multitasking simple.
- Jump to the camera or see notifications without unlocking.
- For incoming calls, you can respond instantly by text.
Rich and interactive notifications let you keep in constant touch with incoming messages, play music tracks, see real-time updates from apps, and much more. On smaller-screen devices, notifications appear at the top of the screen, while on larger-screen devices they appear in the System Bar.
Snapping a screenshot.
Sharing with screenshots
You can now share what’s on your screens more easily by taking screenshots. Hardware buttons let them snap a screenshot and store it locally. Afterward, you can view, edit, and share the screen shot in Gallery or a similar app.
Android has always been cloud-connected, letting you browse the web and sync photos, apps, games, email, and contacts — wherever you are and across all of your devices. Android 4.0 adds new browsing and email capabilities to let you take even more with them and keep communication organized. The Browser tabs menu (left) lets you quickly switch browser tabs. The options menu (right) gives you new ways to manage your browsing experience.
Benchmark comparisons of Android Browser.
Powerful web browsing
The Android Browser offers an experience that’s as rich and convenient as a desktop browser. It lets you instantly sync and manage Google Chrome bookmarks from all of your accounts, jump to your favorite content faster, and even save it for reading later in case there’s no network available.To get the most out of web content, you can now request full desktop versions of web sites, rather than their mobile versions. You can set your preference for web sites separately for each browser tab. For longer content, you can save a copy for offline reading. To find and open saved pages, you can browse a visual list that’s included with browser bookmarks and history. For better readability and accessibility, you can increase the browser’s zoom levels and override the system default text sizes.
In Android 4.0, email is easier to send, read, and manage. For composing email, improved auto-completion of recipients helps with finding and adding frequent contacts more quickly. For easier input of frequent text, you can now create quick responses and store them in the app, then enter them from a convenient menu when composing. When replying to a message, you can now toggle the message to Reply All and Forward without changing screens.
For easier browsing across accounts and labels, the app adds an integrated menu of accounts and recent labels. To help you locate and organize IMAP and Exchange email, the Email app now supports nested mail subfolders, each with synchronization rules. You can also search across folders on the server, for faster results.
For enterprises, the Email app supports EAS v14. It supports EAS certificate authentication, provides ABQ strings for device type and mode, and allows automatic sync to be disabled while roaming. Administrators can also limit attachment size or disable attachments.
For keeping track of incoming email more easily, a resizable Email widget lets you flick through recent email right from the home screen, then jump into the Email app to compose or reply. Android Beam lets you share what you are using with a single tap.
Android 4.0 introduces a completely new approach to securing a device, making each person’s device even more personal — Face Unlock is a new screen-lock option that lets you unlock your device with your face. It takes advantage of the device front-facing camera and state-of-the-art facial recognition technology to register a face during setup and then to recognize it again when unlocking the device. Just hold your device in front of your face to unlock, or use a backup PIN or pattern.
Wi-Fi Direct and Bluetooth HDP
Support for Wi-Fi Direct lets you connect directly to nearby peer devices over Wi-Fi, for more reliable, higher-speed communication. No internet connection or tethering is needed. Through third-party apps, you can connect to compatible devices to take advantage of new features such as instant sharing of files, photos, or other media; streaming video or audio from another device; or connecting to compatible printers or other devices.
Android 4.0 also introduces built-in support for connecting to Bluetooth Health Device Profile (HDP) devices. With support from third-party apps, you can connect to wireless medical devices and sensors in hospitals, fitness centers, homes, and elsewhere.
