14.0.0 (In development)
- Build system:
  - (TODO: More info) Improved library projects
  - Improved incremental builds
    - Resource compilation is run much less frequently. It is no
      longer run when strings are edited, or when layouts are edited
      (unless a new id is introduced), and it is no longer run once
      per library project (!)
    - Resource compilation is no longer done for normal save
      operations, only when running or debugging (option added in ADT
      12 now on by default.)
    - There is a new "PNG crunch cache", which means image crunching
      is only done once, not once per build which is significant for
      projects with many resources
    - Incremental ant builds
  - ADT now uses bin/classes to output the java compilation
    and bin/ for Android specific classes. This will make bin show up
    in the package explorer.
- DDMS
  - Brand new logcat view. Fixes bugs, displays and filters by
    application names instead of just pids, fronts when application
    runs.
- XML Editing
  - New XML formatter which formats all XML files according to the
    standard Android coding style. The formatter can also reorder
    attributes to follow the recommended order.
  - Improved "smart indent": automatic indentation and un-indentation
    when pressing Return in XML editors
  - Go to Matching (Ctrl-Shift-P) in XML files can now jump between
    opening and closing tags
  - Changes made by the layout editor are automatically run through
    the new XML formatter.
  - Select Enclosing Element should now work on the Mac as well.
- Java Editing
  - Quickfix for extracting Strings when the caret is inside a String
- Layout Editor
  - New GridLayout support
  - Tooltip feedback for resizing and dragging operations. For
    example, when dragging in a relative layout, the proposed
    constraints are shown, and when resizing the new dimensions are
    shown.
  - New "Remove Container" visual refactoring which removes the
    children of a container up to the top level and transfers
    namespace and layout attributes if necessary.
  - Improved access to properties in the context menu: The most
    frequently set attributes for each view are listed at the top of
    the menu, and 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.
  - The context menu now also contains pull-right menus for accessing
    properties of the parents, which is useful when the children fully
    cover the parent making it hard to select on its own.
  - Ability to suppress rendering fidelity warnings.
- Asset Studio integration: Wizard creation of launcher icons, menu
    icons, tab icons, etc.
- The New Project and the New XML File wizards have been reworked into
  multiple pages. Sample Projects are now copied into the workspace
  such that they can be modified and deleted without affecting the
  master copy.
- The dependency on Eclipse GEF was removed.
- Many bug fixes, and in particular some critical bug fixes on Linux

13.0.0
- Tools release only (command line tools)

12.0.0 (July 6th, 2011)
- Many bug fixes!
- Visual Layout Editor:
  - New RelativeLayout drop support with guideline suggestions for
    attachments and cycle prevention.
  - Resize support in most layouts. In LinearLayout, sizes are mapped
    to weights. Guideline snapping to wrap_content and match_parent.
  - Previews of drawables and colors in the resource chooser dialogs.
  - Improved error messages and links for rendering errors, including
    detection of misspellings of class names.
- Build system: Delay post compiler phase until actual export or debug
  to speed up interactive file saves. (This is off by default but can
  be enabled in the ADT options panel.)

11.0.0 (June 6th, 2011)
- Visual Refactoring:
  - The new "Extract Style" refactoring pulls out style constants and
    defines them as style rules instead.
  - The new "Wrap in Container" refactoring surrounds the selected
    views with a new layout, and transfers namespace and layout
    parameters to the new parent
  - The new "Change Widget Type" refactoring changes the type of the
    selected views to a new type. (Also, a new selection context menu
    in the visual layout editor makes it easy to select siblings as
    well as views anywhere in the layout that have the same type).
  - The new "Change Layout" refactoring changes layouts from one type
    to another, and can also flatten a layout hierarchy.
  - The "Extract as Include" refactoring now finds identical fragments
    in other layouts and offers to combine all into a single include.
  - There is a new Refactoring Quick Assistant which can be invoked
    from the XML editor (with Ctrl-1) to apply any of the above
    refactorings (and Extract String) to the current selection.
- Visual Layout Editor:
  - Improved "rendering fidelity": The layout preview has been
    improved and should more closely match the rendering on actual
    devices.
  - The visual editor now previews ListViews at designtime.  By
    default, a two-line list item is shown, but with a context menu
    you can pick any arbitrary layout to be used for the list items,
    and you can also pick the header and footer layouts.
  - The palette now supports "configurations" where a single view is
    presented in various different configurations. For example, there
    is a whole "Textfields" palette category where the EditText view
    can be dragged in as a password field, an e-mail field, a phone
    field, and so on. Similarly, TextViews are offered preconfigured
    with large, normal and small theme sizes, and LinearLayouts are
    offered both in horizontal and vertical configurations.
  - The palette supports custom views, picking up any custom
    implementations of the View class in your project source folders
    or in included libraries, and these can be dragged into layouts.
  - Fragments support: Fragments are available in the palette, and in
    the tool you can choose which layout to show rendered for a given
    fragment tag. Go to declaration works for fragment classes.
  - The layout editor automatically applies a "zoom to fit" for newly
    opened files as well as on device size and orientation changes to
    ensure that large layouts are always fully visible unless you
    manually zoom in.
  - You can drop an "include" tag from the palette, which will pop up
    a layout chooser, and the chosen layout is added as an include.
    Similarly, dropping images or image buttons will pop up image
    resource choosers to initialize the new image with.
  - The configuration chooser now applies the "Render Target" and
    "Locale" settings project wide, making it trivial to check the
    layouts for different languages or render targets without having
    to configure these individually for each layout.
  - The layout editor is smarter about picking a default theme to
    render a layout with, consulting factors like theme registrations
    in the manifest, the SDK version, etc.
  - The layout editor is also smarter about picking a default
    configuration to render a layout with, defaulting to the currently
    visible configuration in the previous file. It also considers the
    SDK target to determine whether to default to a tablet or phone
    screen size.
  - Basic focus support: The first text field dropped in a layout is
    assigned focus, and there are "Request Focus" and "Clear Focus"
    context menu items on text fields to change the focus.
- XML editors:
  - Code completion has been significantly improved. It now works
    within <style> elements, it completes dimensional units,
    it sorts resource paths in values based on the attribute name,
    etc. There are also many fixes to handle text replacement.
  - AAPT errors are handled better. They are now underlined for the
    relevant range in the editor, and a new quickfix makes it trivial
    to create missing resources.
  - Code completion for drawable, animation and color XML files.
- DDMS:
  - "New Folder" action in the File Explorer
  - The screenshot dialog will add timestamps to the filenames, and
    preserve the orientation on snapshot refresh
- TraceView: Mouse-wheel zoom support in the timeline
- The New Android Project wizard now supports Eclipse working sets
- Most of the tools have improved integration with the Mac OSX
  system menu bar.
- Most of the tools have new launcher icons.

10.0.1 (March, 2011)
- Temporary work-around to resolve the rare cases in which the layout
  editor will not open.
- Fix issue in which ADT 10.0.0 would install on Eclipse 3.4 and
  lower, even though ADT requires Eclipse 3.5 or higher (as of
  10.0.0).

10.0.0 (February 22nd, 2011)
- The tools now automatically generate Java Programming Language
  source files (in the gen/ directory) and bytecode (in the res/raw/
  directory) from your .rs files.
- A Binary XML editor has been added.
- Traceview is now integrated into the Eclipse UI.
- The "Go To Declaration" feature for XML and .java files quickly show
  all the matches in the project and allows you jump to specific items
  such as string translations or onClick handlers.
- The Resource Chooser can create items such as dimensions, integers,
  ids, and booleans.
- Improvements to the Visual Layout Editor:
  - A new Palette with categories and rendering previews.
  - A Layout Actions bar that provides quick access to common layout
    operations.
  - When the Android 3.0 rendering library is selected, layouts render
    more like they do on devices. This includes rendering of status
    and title bars to more accurately reflect the actual screen space
    available to applications.
  - Zoom improvements such as fit to view, persistent scale, and
    keyboard access..
  - Further improvements to <merge> layouts, as well as layouts with
    gesture overlays.
  - Improved rendering error diagnostics.

9.0.0 (January 26, 2011)
- Visual Layout Editor
    - Empty layouts with 0,0 size are now automatically expanded when
      selected and during drag and drop

      handled
    - Improved support for rendering <include> and <merge> views
    - "Extract as Include" refactoring to extract selected views into
      a separate included layout.
    - String and reference properties can be edited from the layout
      editor's context menu
    - Rewritten outline drag & drop handling, improved label colors
      and content
    - The generated XML will be better formatted. Full XML formatter
      can be enabled in the preferences (under Android > Editors), but
      will touch part of the XML that isn't modified.
    - Automatic configuration of many widgets on drop, such as
      automatically filling a TextView in a vertical LinearLayout,
      adding rows to new tables, etc.
    - Double click views to jump to the corresponding XML declaration,
      or for included views, to the included layout file
    - Improved support for various views (such as TabHosts and
      SlidingDrawers) when rendered using Honeycomb
- Go to Declaration hyperlinks for navigating from @resource
  references to their XML declarations, from the manifest file to
  activity and service classes, from Java access of resource R fields
  to the XML declarations, etc.
- Logcat view in DDMS now properly displays UTF-8 characters.

  projects.
- Better error reporting when exporting applications for release.

8.0.0 (October 2010)
- New version number scheme following the SDK Tools revision number.
- Support for true debug build. No need to change the value of
  debuggable in the Android Manifest.  Incremental build will
  automatically insert debuggable==true while using the "export
  signed/unsigned application package" will not.  If debuggable=true
  is set, then release builds will actually do a debug build.
- Automatic Proguard support in release builds. Only need to have a
  proguard.config property in default.properties that points to a
  proguard config file.
- Completely rewritten Visual Layout Editor. This is very much a work
  in progress.

0.9.8:
- New Action "Rename Application Package" (under the "Android Tools"
  contextual menu) will do a full application package refatoring.
- Fixed issue with library project names containing characters that
  aren't compatible with Eclipse path variable. The link between the
  main project and the library would fail to create.
- Added support for library projects that don't have a source folder
  called "src". There is now support for any number of source folder,
  with no name restriction. They can even be in sub folder such as
  "src/java".
- Added support for libraries with library dependencies.
- added support for new resource qualifiers: car/desk, night/notnight

  make Team plugins ignore them.

0.3.2

- XML Highlighting for AndroidManifest.xml (requires WebTools WST plugin)
- Custom java editor for R.java/Manifest.java to make those files non
  editable. This is to replace the current locking mechanism which
  causes issues on Mac OS.

- Java/Debug/ddms perspective now contains direct menus to open some
  of the ddms views, and to create a new android project. This will
  require you to reset your perspectives.
- Error during builds now put an error marker on the project instead
  of displaying an (annoying) dialog box.
- Custom builders now remember their build state when restarting
  eclipse.
- Properly parse some aapt warnings and don't abort the build when
  they happen.

  to the SDK defined in the preferences.
- Cases where no emulator is running but a dialog still says "An
  emulator is running..." should be less frequent.
- Projects do not reference the standard desktop JRE anymore, as
  android.zip contains the core java library. This will solve the case
  where using a core class non present on the platform would not
  generate a compilation error.
- Changing the package defined in the manifest now deletes the R.java
  class from its previous location. This will require 1 build after
  upgrading the plugin, before it works.
- Project selection in the Launch Config Dialog now only shows Android
  projects.
- Launching a debug/run session now checks that the project uses the
  SDK set in the preferences (This is for the non automatic sync

- The res and assets folders now fully refresh before the build,
  ensuring R.java and packaged resources are always up to date. This
  can be disabled in the preferences under "Android" if this becomes
  slow due to too many files.

0.1.9

- New Action in the "Processes" view to debug an application that is
  already running. The source project for this application MUST be
  opened in the current workspace.
- Building the project now force refreshes the res folder. This should
  help rebuilding the resources when only binary files were changed
  from outside eclipse.
- Clean/full builds now compile all aidl files found in the build path
  (previously only incremental builds would compile them). Also, misc
  improvements to the incremental builders.
- Starting a run/debug session now asks to save the files and forces a
  new build to ensure that the latest package is pushed on the device.
- Plugin should be less aggressive when waiting for the emulator to be
  ready. This should translate in fewer failed launches.

0.1.8

- Fixed Debugger issue introduced in 0.1.6
- Added Log level preferences for DDMS. Look under Android > DDMS >
  Advanced. Default error level is Error.

0.1.7

  messages in the "Android" console when asked to start an
  activity. This should help you figure out what is wrong if the
  application doesn't start.

  code. Now if there are java compile error, the .apk is not touched.
- Added support for manifest with non fully qualified activity java
  name, yet not starting with a dot.
- Fixed creation of manifest files (through New Project wizard) to use
  proper namespace for attributes.
- Better error reporting for namespace issue in the manifest.
- "Reset Adb" action from the device view. Use this is the plugin
  tells you an emulator is running when there are none.
- New "ddms" Console which receives the standard output of ddms.

0.1.5

- Support for new activity declaration inside AndroidManifest.xml
- fixed issue that prevented bin/ to be removed from the buildpath
  when converting project.

0.1.4

- Changes in the Manifest, now properly trigger a new package of the
  resources.

0.1.3

- Fixed the "fix project properties" action to remove old framework
  libraries, just not add new ones.

  explorer contextual menu. This allows you to fix the framework path
  (and its javadoc path) in case you change the sdk location.

0.1.1

- Fixed project convertor to add the framework library if missing.

0.1.0

- New project wizard.
- Python script-generated project convertor.
- Incremental builders.
