android eclipse开发插件ADT 14.0.0 更新记录

安装 android-14 (4.0的sdk) 后，eclipse的adt插件进行了配套升级，发现adt新版本还是挺大的，简单将英文版翻译了一点（中括号包含的部分是我自行添加的说明），内容如下

编译系统（这一部分的变化较大）
1. 将default.properties改为project.properties，将build.properties改为ant.properties
2. 改变了Eclipse中library项目编译的方式 [现在在library project的bin目录下会生成一个jar]
3. 将javac输出的结果放在bin/classes目录中，原来是bin目录
4. 改进了增量构建，降低了资源文件编译的次数。编辑字符串或布局文件时，只有新增或修改了id时才重新进行资源的编译
5. Introduced a "PNG crunch cache" that only runs on modified PNG files, instead of crunching all existing PNG files, all the time.
6. 普通文件的保存不会触发资源文件的编译 [第4条不算普通文件的保存] ，仅在需要running或debugging的时候才进行 [可以在Preferences->Android->Build->Skip package and dexing...里改变这个默认的行为]。

通用改进（这一部分的变化较大）
1. 添加了一个Welcome向导，用来帮助创建android开发环境
2. 集成了android asset studio，用来创建各类icon，如启动icon、menu和tab中的icon
3. 改进了logcat视图
4. 改进了SDK Manager的UI
5. 将创建新项目和xml文件的向导改为多页[原来在一页内，通过滚动条来显示各部分，常常造成不必要的疑惑]。创建android自带的例子项目时，源文件拷贝到workspace中去。
6. 去掉了对Eclipse GEF的依赖

xml和java编辑器
1. Added a new XML formatter that formats all XML files according to the standard Android coding style. The formatter can also reorder attributes to follow a recommended order and processes any changes made in the Layout editor
2. 添加了"Go to Matching"(ctrl-shift-P)特性，可以快速在xml标签的开头和结尾处快速切换
3. Added support for the "Select Enclosing Element" feature on Mac
4. Added a Quickfix for extracting Strings when the caret is inside a String
5. Improved "smart indent", which allows automatic indentation and un-indentation when pressing the Return key in XML editors[智能缩进]

layout编辑器
1. Added tooltip feedback for dragging and resizing operations. For example, when dragging in a relative layout, the proposed constraints are shown. When resizing, the new dimensions are shown
2. Added the ability to suppress rendering fidelity warnings
3. Added "Remove Container" visual refactoring that removes the children of a container up to the top level and transfers namespace and layout attributes if necessary 
4. Added pull-right menus to the context menu for accessing properties of the parents, which is useful when the children fully cover the parent and make it hard to select on their own
5. Improved access to properties in the context menu. The most frequently set attributes for each view are listed at the top of the menu. The Properties menu offers access to the most recently set attributes, attributes organized by their defining view, and layout attributes only or all attributes alphabetically
