This is the full length Android Demo video(Youtube) from keynote day 2 at Google I/O, a cute android video where you can learn all of the details about Android 2.2 with funny from Vic Gundotra, Google vice president of developer platforms.
According offical android developers blog, the following five areas about android 2.2 are highlighted in particular:
Performance & speed: The new Dalvik JIT compiler in Android 2.2 delivers between a 2-5X performance improvement in CPU-bound code vs. Android 2.1 according to various benchmarks.
New enterprise capabilities: We’ve added Exchange capabilities such as account auto-discovery and calendar sync. Device policy management APIs allow developers to write applications that can control security features of the device such as the remote wipe, minimum password, lockscreen timeout etc.
Rich set of new APIs and services: New data backup APIs enable apps to participate in data backup and restore, allowing an application’s last data to be restored when installed on a new or a reset device. Apps can utilize Android Cloud to Device Messaging to enable mobile alert, send to phone, and two-way push sync functionality. Developers can now declare whether their app should be installed on internal memory or an SD card. They can also let the system automatically determine the install location. On the native side, a new API now gives access to Skia bitmaps.
Additions to Android Market: Android Market provides Android Application Error Reports, a new bug reporting feature, giving developers access to crash and freeze reports from users. Developers will be able to access these reports via their account on the Android Market publisher website.

Google I/O 2010 will be held from May 19 to 20 in San Francisco, during the 2-day conference, over 90 technical sessions will provide the opportunities for developers to meet others from over 170 companies. Android will have a big presence at this year’s event. Except this year’s gift is a free Android phone (Google Nexus One for International guests and Motorola Droid for US developers), Google I/O will feature 6 Android sessions for developers:
A beginner’s guide to Android
This session will introduce some of the basic concepts involved in Android development. Starting with an overview of the SDK APIs available to developers, we will work through some simple code examples that explore some of the more common user features including using sensors, maps, and geolocation.
Casting a wide net: how to target all Android devices
One of Android’s strengths is its flexibility to run on a wide variety of devices. In this session, we will explore the facilities the Android resource system provides to developers to make supporting many devices from one application binary easier, as well as common pitfalls. In addition to hardware heterogeneity, more than one version of Android may exist in the wild at any given time. We will go over strategies for providing cross-version compatibility.
Home sweet home
Android applications do not have a single point of entry and can become deeply integrated with the system. In this session, you will learn the various ways you can make your app offer more features to your users and make it part of the Home experience.
Writing real-time games for Android redux
This session is a crash course in Android game development: everything you need to know to get started writing 2D and 3D games, as well as tips, tricks, and benchmarks to help your code reach optimal performance. In addition, we’ll discuss hot topics related to game development, including hardware differences across devices, using C++ to write Android games, and the traits of the most popular games on Market.
Android UI design patterns
In this session, the Android User Experience team will show the types of patterns you can use to build a great Android application. We’ll cover things like how to use Interactive Titlebars, Quick Contacts, and Bottom bars as well some new patterns which will get an I/O-only preview. The team will be also available for a no holds barred Q&A session.
A JIT Compiler for Android’s Dalvik VM
In this session we will outline the design of a JIT Compiler suitable for embedded Android devices. Topics will include an architectural overview, the rationale for design decisions and the special support for JIT verification, testing and tuning.
