The Android 2.2 platform introduces many new and exciting features for +users and developers. This document provides a glimpse at some of the new user features +and technologies in Android 2.2. For more information about the new developer APIs, see the Android 2.2 version notes.

+ New Home screen tips widget assists new users on how to configure the +home screen with shortcuts and widgets and how to make use of multiple home screens. +The Phone, applications Launcher, and Browser now have dedicated +shortcuts on the Home screen, making it easy to access them from any of the 5 home screen +panels. + |
+

+
+ Flash: Browser is able to fully support the latest version of Flash so +the web experience is even closer to the desktop. Adobe Flash will be available to download from +Android Market. +Performance of the browser has been enhanced using the V8 engine, +which enables faster loading of JavaScript-heavy pages. + |
+
|
+ Improved security with the addition of numeric pin or alpha-numeric +password options to unlock device. Exchange administrators can enforce password policy across +devices. +Remote wipe: Exchange administrators can remotely reset the device to +factory defaults to secure data in case device is lost or stolen. +Exchange Calendars are now supported in the Calendar application. +Auto-discovery: you just need to know your user-name and password to +easily set up and sync an Exchange account (available for Exchange 2007 and higher). +Global Address Lists look-up is now available in the Email +application, enabling users to auto-complete recipient names from the directory. + |

+
+ Gallery allows you to peek into picture stacks using a zoom +gesture. +Camera onscreen buttons provide easy access to a new UI for +controling zoom, flash, white balance, geo-tagging, focus and exposure. Camcorder also provides +an easy way to set video size/quality for MMS and YouTube. +With the LED flash now enabled for the Camcorder, videos can be shot +at night or in low light settings. + |
+
|
+ Certain devices like the Nexus One can be turned into a portable Wi-Fi +hotspot that can be shared with up to 8 devices. +You can use your Android-powered phone as a 3G connection for a Windows or Linux laptop by +connecting their phone to the computer with a USB cable. The connection is then shared between the +two devices. + |
+
+

+
+
+ |
+
+ Multi-lingual users can add multiple languages to the keyboard and switch +between multiple Latin-based input languages by swiping across the space bar. This changes +the keys as well as the auto-suggest dictionary. + |
+
|
+ Dalvik Performance Boost: 2x-5x performance speedup for CPU-heavy code +over Android 2.1 with Dalvik JIT. +The graph to the right shows the performance speedup from Android 2.1 +to Android 2.2 using various benchmark tests. For example, LinPack is now more than 5 times +faster. +Kernel Memory Management Boost: Improved memory reclaim by up to 20x, +which results in faster app switching and smoother performance on memory-constrained devices. + |
+

+
Apps can utilize Android Cloud to Device Messaging to enable mobile alert, send to phone, and +two-way push sync functionality.
+ + +New bug reporting feature for Android Market apps enables developers to receive crash and freeze +reports from their users. The reports will be available when they log into their publisher +account.
+ + + + +Applications can now request installation on the shared external storage (such as an SD +card).
+ + +Provides new APIs for audio focus, routing audio to SCO, and auto-scan of files to media +database. Also provides APIs to let applications detect completion of sound loading and auto-pause +and auto-resume audio playback.
+ + +New preview API doubles the frame rate from ~10FPS to ~20FPS. Camera now supports portrait +orientation, zoom controls, access to exposure data, and a thumbnail utility. A new camcorder +profile enables apps to determine device hardware capablities.
+ + +New APIs for OpenGL ES 2.0, working with YUV image format, and ETC1 for texture +compression.
+ + +Apps can participate in data backup and restore, to ensure that users maintain their data +after performing a factory reset or when switching devices.
+ + +New device policy management APIs allow developers to write "device administrator" applications +that can control security features on the device, such as the minimum password strength, data wipe, +and so on. Users can select the administrators that are enabled on their devices.
+ + +New "car mode" and "night mode" controls and configurations allow applications to adjust their UI +for these situations. A scale gesture detector API provides improved definition of multi-touch +events. Applications can now customize the bottom strip of a TabWidget.
