Apple - iOS 5 - See new features included in iOS 5.

Notification Center All your alerts. All in one place. You get all kinds of notifications on your iOS device: new email, texts, friend requests, and more. With Notification Center, you can keep track of them all in one convenient location. Just swipe down from the top of any screen to enter Notification Center. Choose which notifications you want to see. Even see a stock ticker and the current weather. New notifications appear briefly at the top of your screen, without interrupting what you’re doing. And the Lock screen displays notifications so you can act on them with just a swipe. Notification Center is the best way to stay on top of your life’s breaking news.

Newsstand A custom newsstand for all your subscriptions. Read all about it. All in one place. iOS 5 organizes your magazine and newspaper app subscriptions in Newsstand: a folder that lets you access your favorite publications quickly and easily. There’s also a new place on the App Store just for newspaper and magazine subscriptions. And you can get to it straight from Newsstand. New purchases go directly to your Newsstand folder. Then, as new issues become available, Newsstand automatically updates them in the background — complete with the latest covers. It’s kind of like having the paper delivered to your front door. Only better.

Reminders A better way to do to-dos. Next time you think to yourself, “Don’t forget to...,” just pull out your iPhone, iPad, or iPod touch and jot it down. Reminders lets you organize your life in to-do lists — complete with due dates and locations. Say you need to remember to pick up milk during your next grocery trip. Since Reminders can be location based, you’ll get an alert as soon as you pull into the supermarket parking lot. Reminders also works with iCal, Outlook, and iCloud, so changes you make update automatically on all your devices and calendars.

Twitter Integrated right into iOS 5. iOS 5 makes it even easier to tweet from your iPhone, iPad, or iPod touch. Sign in once in Settings, and suddenly you can tweet directly from Safari, Photos, Camera, YouTube, or Maps. Want to mention or @reply to a friend? Contacts applies your friends’ Twitter usernames and profile pictures. So you can start typing a name and iOS 5 does the rest. You can even add a location to any tweet, no matter which app you’re tweeting from.

Camera Capture the moment at a moment’s notice. Since your iPhone is always with you, it’s often the best way to capture those unexpected moments. That’s why you’ll love the new camera features in iOS 5. You can open the Camera app right from the Lock screen. Use grid lines, pinch-to-zoom gestures, and single-tap focus and exposure locks to compose a picture on the fly. Then press the volume-up button to snap your photo in the nick of time. If you have Photo Stream enabled in iCloud, your photos automatically download to all your other devices.

Photos Enhanced photo enhancements. Turn your snapshots into frame-worthy photos in just a few taps. Crop, rotate, enhance, and remove red-eye without leaving the Photos app. Even organize your photos in albums — right on your device. With iCloud, you can push new photos to all your iOS devices. So if you’re taking photos on your iPhone, iCloud automatically sends copies to your iPad, where you can quickly touch them up before showing them off.

Safari Even better site-seeing. iOS 5 brings even more web-browsing features to iPhone, iPad, and iPod touch. Safari Reader displays web articles sans ads or clutter so you can read without distractions. Reading List lets you save interesting articles to peruse later, while iCloud keeps your list updated across all your devices. On iPad, tabbed browsing helps you keep track of multiple web pages and switch between them with ease. And iOS 5 improves Safari performance on all your iOS devices.

PC Free Independence for all iOS devices. With iOS 5, you no longer need a computer to own an iPad, iPhone, or iPod touch. Activate and set up your device wirelessly, right out of the box. Download free iOS software updates directly on your device. Do more with your apps — like editing your photos or adding new email folders — on your device, without the need for a Mac or PC. And back up and restore your device automatically using iCloud.

Mail Your inbox is about to receive some great new features. Format text using bold, italic, or underlined fonts. Create indents in the text of your message. Drag to rearrange names in address fields. Flag important messages. Even add and delete mailbox folders on the fly. If you’re looking for a specific email, you can now search in the body of messages. And with iCloud, you get a free email account that stays up to date on all your devices.

Wi-Fi Sync Wirelessly sync your iOS device to your Mac or PC over a shared Wi-Fi connection. Every time you connect your iOS device to a power source (say, overnight for charging), it automatically syncs and backs up any new content to iTunes. So you always have your movies, TV shows, home videos, and photo albums everywhere you want them.

What is Android?

Android is a software stack for mobile devices that includes an operating system, middleware and key applications. The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language. Features Application framework enabling reuse and replacement of components Dalvik virtual machine optimized for mobile devices Integrated browser based on the open source WebKit engine Optimized graphics powered by a custom 2D graphics library; 3D graphics based on the OpenGL ES 1.0 specification (hardware acceleration optional) SQLite for structured data storage Media support for common audio, video, and still image formats (MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, GIF) GSM Telephony (hardware dependent) Bluetooth, EDGE, 3G, and WiFi (hardware dependent) Camera, GPS, compass, and accelerometer (hardware dependent) Rich development environment including a device emulator, tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDE Android Architecture The following diagram shows the major components of the Android operating system. Each section is described in more detail below.

Applications Android will ship with a set of core applications including an email client, SMS program, calendar, maps, browser, contacts, and others. All applications are written using the Java programming language. Application Framework By providing an open development platform, Android offers developers the ability to build extremely rich and innovative applications. Developers are free to take advantage of the device hardware, access location information, run background services, set alarms, add notifications to the status bar, and much, much more. Developers have full access to the same framework APIs used by the core applications. The application architecture is designed to simplify the reuse of components; any application can publish its capabilities and any other application may then make use of those capabilities (subject to security constraints enforced by the framework). This same mechanism allows components to be replaced by the user. Underlying all applications is a set of services and systems, including: A rich and extensible set of Views that can be used to build an application, including lists, grids, text boxes, buttons, and even an embeddable web browser Content Providers that enable applications to access data from other applications (such as Contacts), or to share their own data A Resource Manager, providing access to non-code resources such as localized strings, graphics, and layout files A Notification Manager that enables all applications to display custom alerts in the status bar An Activity Manager that manages the lifecycle of applications and provides a common navigation backstack For more details and a walkthrough of an application, see the Notepad Tutorial. Libraries Android includes a set of C/C++ libraries used by various components of the Android system. These capabilities are exposed to developers through the Android application framework. Some of the core libraries are listed below: System C library - a BSD-derived implementation of the standard C system library (libc), tuned for embedded Linux-based devices Media Libraries - based on PacketVideo's OpenCORE; the libraries support playback and recording of many popular audio and video formats, as well as static image files, including MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG Surface Manager - manages access to the display subsystem and seamlessly composites 2D and 3D graphic layers from multiple applications LibWebCore - a modern web browser engine which powers both the Android browser and an embeddable web view SGL - the underlying 2D graphics engine 3D libraries - an implementation based on OpenGL ES 1.0 APIs; the libraries use either hardware 3D acceleration (where available) or the included, highly optimized 3D software rasterizer FreeType - bitmap and vector font rendering SQLite - a powerful and lightweight relational database engine available to all applications Android Runtime Android includes a set of core libraries that provides most of the functionality available in the core libraries of the Java programming language. Every Android application runs in its own process, with its own instance of the Dalvik virtual machine. Dalvik has been written so that a device can run multiple VMs efficiently. The Dalvik VM executes files in the Dalvik Executable (.dex) format which is optimized for minimal memory footprint. The VM is register-based, and runs classes compiled by a Java language compiler that have been transformed into the .dex format by the included "dx" tool. The Dalvik VM relies on the Linux kernel for underlying functionality such as threading and low-level memory management. Linux Kernel Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack.
