After the Android-14 (4.0 SDK) is installed, the ADT plug-in of eclipse is upgraded to a large version, I simply translated the English version a little (the section in the brackets is my own description). The content is as follows:
Compilation System (This part has changed a lot)
1. Change default. properties to project. properties, and change build. properties to ant. properties.
2. Changed the Library Project Compilation Method in eclipse [Now a jar file is generated in the bin directory of the Library Project.]
3. Put the result of javac output in the bin/classes directory. It turns out to be the bin directory.
4. Improved incremental build and reduced the number of resource file compilation times. When editing a string or layout file, recompile the resource only when the ID is added or modified.
5. introduced a "PNG crunch cache" that only runs on modified PNG files, instead of crunching all existing PNG files, all the time.
6. Saving normal files will not trigger compilation of resource files [4th records are not counted as saving normal files]. Only running or debugging is required [You can change the default behavior in preferences-> Android-> build-> skip package and Dexing ....].
General improvements (great changes in this Part)
1. added a welcome Wizard to help you create an android development environment.
2. Integrated with Android asset studio, it is used to create various icons, such as start icon, menu and icon in Tab
3. Improved the logcat View
4. Improved the SDK Manager UI
5. Change the wizard for creating new projects and XML files to multiple pages. [the original page displays various parts through the scroll bar, which often causes unnecessary doubts.] When creating an example project that comes with Android, copy the source file to the workspace.
6. removed the dependency on Eclipse GEF.
XML and Java editors
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. added the "go to matching" (CTRL-shift-p) feature to quickly switch between the beginning and end of an XML tag.
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 [smart indent]
Layout Editor
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
