Andriod hi Kyun (Why Andriod only)
Introducing Android 4.0
Android 4.0 (Ice Cream Sandwich) is and 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, Easiest to use, customizable home screens, resizable widgets, and deep
interactivity and much more lot of Another Application can run at Single platforms — 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
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.
Jump to the camera or see notifications without unlocking.
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.
Home screen folders and favorites tray
New home screen folders offer a new way for you to group your apps and shortcuts
logically, just by dragging one onto another. Also, in All Apps launcher, you can now
simply drag an app to get information about it or immediately uninstall it, or disable a
New lock screen actions
The lock screens now let you do more without unlocking. From the slide lock screen, you
can jump directly to the camera for a picture or pull down the notifications window to
check for messages. When listening to music, you can even manage music tracks and see
Quick responses for incoming calls
When an incoming call arrives, you can now quickly respond by text message, without
needing to pick up the call or unlock the device. On the incoming call screen, you simply
slide a control to see a list of text responses and then tap to send and end the call.
You can add your own responses and manage the list from the Settings app.
Swipe to dismiss notifications, tasks, and browser tabs
Android 4.0 makes managing notifications, recent apps, and browser tabs even easier. You
can now dismiss individual notifications, apps from the Recent Apps list, and browser
tabs with a simple swipe of a finger.
Improved text input and spell-checking
The soft keyboard in Android 4.0 makes text input even faster and more accurate. Error
correction and word suggestion are improved through a new set of default dictionaries and
more accurate heuristics for handling cases such as double-typed characters, skipped
letters, and omitted spaces. Word suggestion is also improved and the suggestion strip is
simplified to show only three words at a time.
To fix misspelled words more easily, Android 4.0 adds a spell-checker that locates and
underlines errors and suggests replacement words. With one tap, you can choose from
multiple spelling suggestions, delete a word, or add it to the dictionary. You can even
tap to see replacement suggestions for words that are spelled correctly. For specialized
features or additional languages, you can now download and install third-party
dictionaries, spell-checkers, and other text services.
Powerful voice input engine
Android 4.0 introduces a powerful new voice input engine that offers a continuous “open
microphone” experience and streaming voice recognition. The new voice input engine lets
you dictate the text you want, for as long as you want, using the language you want. You
can speak continously for a prolonged time, even pausing for intervals if needed, and
dictate punctuation to create correct sentences. As the voice input engine enters text,
it underlines possible dictation errors in gray. After dictating, you can tap the
underlined words to quickly replace them from a list of suggestions.
Control over network data
Mobile devices can make extensive use of network data for streaming content,
synchronizing data, downloading apps, and more. To meet the needs of you with tiered or
metered data plans, Android 4.0 adds new controls for managing network data usage.
In the Settings app, colorful charts show the total data usage on each network type
(mobile or Wi-Fi), as well as amount of data used by each running application. Based on
your data plan, you can optionally set warning levels or hard limits on data usage or
disable mobile data altogether. You can also manage the background data used by
individual applications as needed.
Designed for accessibility
A variety of new features greatly enhance the accessibility of Android 4.0 for blind or
visually impaired users. Most important is a new explore-by-touch mode that lets you
navigate without having to see the screen. Touching the screen once triggers audible
feedback that identifies the UI component below; a second touch in the same component
activates it with a full touch event. The new mode is especially important to support
users on new devices that use virtual buttons in the System Bar, rather than dedicated
hardware buttons or trackballs. Also, standard apps are updated to offer an improved
accessibility experience. The Browser supports a script-based screen reader for reading
favorite web content and navigating sites. For improved readability, you can also
increase the default font size used across the system.
The accessibility experience begins at first setup — a simple touch gesture during setup
(clockwise square from upper left) activates all accessibility features and loads a setup
tutorial. Once accessibility features are active, everything visible on the screen can be
spoken aloud by the standard screen reader.
Communication and sharing
Throughout the system, your social groups, profiles, and contacts are linked together and
integrated for easy accessibility. At the center is a new People app that offers richer
profile information, including a large profile picture, phone numbers, addresses and
accounts, status updates, events, and a new button for connecting on integrated social
Your contact information is stored in a new “Me” profile, allowing easier sharing with
apps and people. All of your integrated contacts are displayed in an easy to manage list,
including controls over which contacts are shown from any integrated account or social
network. Wherever you navigate across the system, tapping a profile photo displays Quick
Contacts, with large profile pictures, shortcuts to phone numbers, text messaging, and
Unified calendar, visual voicemail
To help organize appointments and events, an updated Calendar app brings together
personal, work, school, and social agendas. With user permission, other applications can
contribute events to the calendar and manage reminders, for an integrated view across
multiple calendar providers. The app is redesigned to let you manage events more easily.
Calendars are color-coded and you can swipe left or right to change dates and pinch to
zoom in or out agendas.
In the phone app, a new visual voicemail features integrates incoming messages, voice
transcriptions, and audio files from one or more providers. Third-party applications can
integrate with the Phone app to add your own voice messages, transcriptions, and more to
the visual voicemail inbox.
Rich and versatile camera capabilities
The Camera app includes many new features that let you capture special moments with
great photos and videos. After capturing images, you can edit and share them easily
When taking pictures, continuous focus, zero shutter lag exposure, and decreased
shot-to-shot speed help capture clear, precise images. Stabilized image zoom lets you
compose photos and video in the way you want, including while video is recording. For
new flexibility and convenience while shooting video, you can now take snapshots at
full video resolution just by tapping the screen as video continues to record.
To make it easier to take great pictures of people, built-in face detection locates
faces in the frame and automatically sets focus. For more control, you can tap to focus
anywhere in the preview image.
For capturing larger scenes, the Camera introduces a single-motion panorama mode. In
this mode, you start an exposure and then slowly turn the Camera to encompass as wide a
perspective as needed. The Camera assembles the full range of continuous imagery into a
single panoramic photo.
After taking a picture or video, you can quickly share it by email, text message,
bluetooth, social networks, and more, just by tapping the thumbnail in the camera
Redesigned Gallery app with photo editor
The Gallery app now makes it easier to manage, show, and share photos and videos. For
managing collections, a redesigned album layout shows many more albums and offers
larger thumbnails. There are many ways to sort albums, including by time, location,
people, and tags. To help pictures look their best, the Gallery now includes a powerful
photo editor. You can crop and rotate pictures, set levels, remove red eyes, add
effects, and much more. After retouching, you can select one or multiple pictures or
videos to share instantly over email, text messaging, bluetooth, social networks, or
An improved Picture Gallery widget lets you look at pictures directly on the home
screen. The widget can display pictures from a selected album, shuffle pictures from
all albums, or show a single image. After adding the widget to the home screen, you can
flick through the photo stacks to locate the image you want, then tap to load it in
Live Effects for transforming video
Live Effects is a collection of graphical transformations that add interest and fun to
videos captured in the Camera app. For example, you can change the background behind
them to any stock or custom image, for just the right setting when shooting video. Also
available for video is Silly Faces, a set of morphing effects that use state-of-the-art
face recognition and GPU filters to transform facial features. For example, you can use
effects such as small eyes, big mouth, big nose, face squeeze, and more. Outside of the
Camera app, Live Effects is available during video chat in the Google Talk app.
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,

the V8 benchmark and nearly 70% in the SunSpider benchmark.
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
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,
