最近發現SDK 可以更新, 主要是改善虛擬機效能問題. 對於Android 平台來說是一個很重要的更新.
因為用戶的Android 種類太多 囧rz 所以常常要用到虛擬機....
General notes:

這邊是官方的資料 :
- Emulator
- Added support for hardware accelerated graphics rendering. This feature requires an API Level 15, Revision 3 or later system image. (more info)Note: As of the SDK Tools Revision 17 release, the API Level 15, Revision 3 system image is not yet available.
- Added support for running Android x86 system images in virtualization mode on Windows and Mac OS X. (more info)
- Added experimental support for multi-touch input by enabing the emulator to receive touch input from a USB-tethered physical Android device. (more info)
- Added support for hardware accelerated graphics rendering. This feature requires an API Level 15, Revision 3 or later system image. (more info)
- Added viewing of live detailed network usage of an app in DDMS. (more info)
- ProGuard
- Updated the bundled ProGuard tool to version 4.7. In addition to many new features, this update fixes the
Conversion to Dalvik format failed with error 1error some users have experienced. - Updated the default
proguard.cfgfile with better default flags for Android. - Split the ProGuard configuration file has been in half, with project specific flags kept in project and the generic Android flags distributed (and updated) with the tools themselves.
- Updated the bundled ProGuard tool to version 4.7. In addition to many new features, this update fixes the
- Build
- Added a feature that allows you to run some code only in debug mode. Builds now generate a class called
BuildConfigcontaining aDEBUGconstant that is automatically set according to your build type. You can check the (BuildConfig.DEBUG) constant in your code to run debug-only functions. - Fixed issue when a project and its libraries include the same jar file in their libs folder. (more info)
- Added support for custom views with custom attributes in libraries. Layouts using custom attributes must use the namespace URI
http://schemas.android.com/apk/res-autoinstead of the URI that includes the app package name. This URI is replaced with the app specific one at build time.
- Added a feature that allows you to run some code only in debug mode. Builds now generate a class called
- Lint
- Updated Lint to check Android application code. Lint rules which previously performed pattern based searches in the application code (such as the unused resource check) have been rewritten to use the more accurate Java-style parse trees.
- Added support for checking library projects. This change means that rules such as the unused resource check properly handle resources declared in a library project and referenced in a downstream project.
- Added ability to suppress Lint warnings in Java code with the new
@SuppressLintannotation, and in XML files with the new tools: namespace and ignore attribute. (more info) - New Lint checks:
- Added check for Android API calls that require a version of Android higher than the minimum supported version. You can use the new
@TargetApiannotation to suppress warnings when the code is wrapped in a system version condition. (more info) - Added over 20 new Lint rules, including checks for performance, XML layouts, manifest and file handling.
- Added check for Android API calls that require a version of Android higher than the minimum supported version. You can use the new
以上 Hardware accelerated graphics 我自己是用不了 一直出錯誤, 可能電腦有什麼地方設不好吧...
另外 x86 的虛擬機速度上有接近實體機了, 不過在跑自己Project 時還是有點小問題
其他功能待測 ( 懶惰 ) ~
