Complete rewrite of the library to backport the Android 4.0 action bar.

• The minimum supported version of Android is now 2.1 (API 7).
• New base activities are provided (e.g., SherlockActivity and SherlockFragmentActivity) which extend from the native activities.
• The support library sources are no longer included in the library. You must include android-support-v4.jar in your project separately.
• Theming now mirrors that of the native action bar through the use of multiple styles rather than through ab- and am-prefixed attributes in the theme.
• The action bar can be statically attached to an activity view without the requirement of using one of the provided base activities.

• Fix: NullPointerException in FragmentManager can no longer occur when an attempt is being made to save to a Bundle that has not yet been created.
• Fix: Pre-3.0 action item submenu dialogs now properly dismiss themselves when an item of theirs is selected.

• Library now uses the r6 version of the compatibility library for its base. Ice Cream Sandwich-specific implementations are currently disabled, however, but will be added in a future version of the library.

MenuCompat, MenuItemCompat, and ActivityCompat have be added back in to ease transition to this library but all their methods and the classes themselves have been deprecated.

• Rewritten menu and action item support from Ice Cream Sandwich.
• Removed the need for the custom Window.FEATURE_ACTION_ITEM_TEXT flag. You should now use the showAsAction attribute and/or the setShowAsAction(int) method on each MenuItem to control whether or not text is shown
• Action item dividers are now added automatically only when necessary to distinguish possible confusion between action items.
• Fix: Action views now properly size themselves within the bounded space of the menu.
• Fix: List navigation no longer becomes unusable on certain device configurations.
• Fix: SubMenu's findItem(int) method now properly returns the support version of MenuItem.
• Fix: Invisible sub-menu items are no longer shown on the pre-3.0 popup list.

• Fix: Stacked action bar now properly sets the tab bar background based on the theme.

• The makeFragmentName method in FragmentPagerAdapter has been changed to public scope to allow for easier access to your fragments that it is managing.
• Action bar will now animate when calling show() or hide().
• SherlockPreferenceActivity now provides full fragment and loader support.
• Examples for the plugins are now in their own sample application.
• Fix: Home icon no longer erroneously clipped when it exceeds the size of the action bar.
• Fix: Tabs will now scroll horizontally to mimic the native action bar behavior.
• Fix: Plugins now properly DO NOT inline their R.java integer constants.
• Fix: Tabs below the action bar are now styled with a default background so that they do not incorrectly inherit an applied background unless explicity declared.

• Library now uses the r4 version of the compatibility library for its base. Ice Cream Sandwich-specific implementations are currently disabled, however, but will be added in a future version of the library.
• Context menu callbacks now use the support version of MenuItem to maintain consistency.
• Added preference plugin which provides an action bar enhanced preference screen.
• Fix: abHomeLayout theme attribute is now honored.
• Fix: onPrepareOptionsMenu is now properly dispatched upon menu invalidation.

ADT 14 is now required. Maven 3 is required if building from the command line.

• XML-defined onClick attributes will now check for an onClick method that takes an android.support.v4.view.MenuItem instance.
• Tabs on medium screens in landscape now display inline rather than below the action bar to mirror how Android 4.0 behaves with the same configuration.
• Fix: Menu inflater properly checks activity context for onClick method declared in the XML.
• Fix: Dialog fragment properly saves its showDialog state when not being used as a popup.
• Fix: Return -1 when in tab navigation but no tab is selected. This brings the library in line with the post-3.0 behavior.
• Fix: Removing a menu group no longer throws an IndexOutOfBoundsException.
• Fix: getSelectedTab and getTabAt no longer throw NullPointerExceptions on post-3.0 when no tab was selected or no tab existed at the specified position, respectively.
• Fix: findFragmentById now properly returns fragments attached to android.R.id.content when run on pre-3.0 devices.

• Tabs are now displayed below the action bar on all medium-screen devices and portrait large-screen devices.
• Fix: Dialog fragments no longer throw an IllegalStateException when being used as a regular fragment (i.e., not as a popup). See StackOverflow for more information.
• Fix: Popping a fragment off of the back stack now properly assigns its parent activity.
• Fix: An activity result no longer causes a NullPointerException when the target fragment no longer exists.
• Fix: Action item dividers are now properly initially hidden when their associated action items are as well.

• Fix: Fragments in a ViewPager that contributed items to the options menu were caught in a race condition causing inconsistent results when a new page was selected. This regression was introduced in version 3.2.2.

• Fix: Side-effects related to using FragmentMapActivity due to how it was referencing resources from the main library.
• Fix: Fragments adjacent to the currently selected fragment in a ViewPager no longer receive context menu events.
• Fix: Eliminate exception when inflating context menus on 3.0+ when using getMenuInflater().
• Fix: ViewPager now determines whether or not an activity menu invalidation is required independently of whether or not fragments were created or destroyed. This should fix an edge case where an activity with a ViewPager containing only two fragments would not get its menu properly invalidated.

• Fix: Action mode API incorrectly using the native Menu and MenuItem classes causing an easy pitfall for ClassCastExceptions.
• Fix: Large action bar backgrounds increasing the size beyond that alloted in the theme.

• Added support for MapView and the Google APIs through the use of FragmentMapActivity. If you are using a map within a fragment you must ensure it is always attached to an activity which extends from this new base class.

Since supporting maps requires compiling against the Google APIs, this functionality is implemented in the form of a plugin which is to be used alongside the normal library. You can choose to add it as an additional library project or by including it as a .jar. Maven users may simply include the additional dependency (artifactId: plugin-maps).

• Fix: Fragments adjacent to the currently selected fragment in a ViewPager no longer contribute to the activity menu.
• ActionBar.Tab has been changed from an interface to an abstract class to mirror its native counterpart.

• Renamed all resources to be prefixed with abs__ to avoid conflicts when including in your project.
• Fix: Action bar background being set on two views causing artifacts to remain on screen when the action bar was hidden.
• Fix: Incorrect sub-menu item being selected by default when the sub-menu was triggered from the native options menu on pre-3.0.
• Fix: MenuItem.setVisible now properly updates the associated action item and native menu item visible state.
• Fix: Adding items to a menu now honors its ordering and category.
• Fix: Fragment options item selected callback now uses the proper version of MenuItem.

• Fix: MenuItem.getMenuInfo() was throwing runtime exception. Will now just return null.
• Fix: Dragging over a WebView contained in a ViewPager would not register.
• Fix: Inflation of context menu incorrectly being handled by the custom menu inflater for the library.

• Fix: MenuItem.getSubMenu now returns a support instance rather than a native instance.
• Fix: Fragment methods onAttach and onInflate incorrectly regressed to use Activity instead of a FragmentActivity in their method signatures.
• Fix: Retained fragments not being re-attached on pre-3.0 when attached to android.R.id.content upon activity recreation.
• Fix: onPrepareOptionsMenu not dispatched to fragments. This still will only occur if the activity method returns true (which is the default).
• Fix: Menu.findItem not returning null when the item was not found on Android 3.0+.

Due to shortcomings in the Android theming system, a small change must be made in how this library handles themes. If you were using a custom style for actionBarStyle you must now specify its attributes in the root of the theme and prefix them with 'ab'.

You can see an example of this in the SherlockCustom theme in samples/demos/res/values/styles.xml.

• Library now uses the r3 version of the compatibility library for its base.
• actionBarStyle is no longer a valid theme attribute (see note above).
• Added the demo project included with the new compatibility library under samples/demos/ and merged in the old 'featuredemo'.
• Dividers are now shown on pre-3.0 devices between all action items.
• Window.FEATURE_ACTION_BAR_OVERLAY is now honored on pre-3.0 devices.
• Inflation of XML menu resources will now honor android:actionLayout and android:actionViewClass attributes.
• Buttons for displaying the determinate and indeterminate progress bars have been added to the feature toggle demo.
• Added support for indeterminate progress bar. Due to the final modifier on the native type, you must use setIndeterminateProgressBarVisibility(Boolean) and pass Boolean.TRUE or Boolean.FALSE.
• Fix: MenuBuilder#removeItem(int) and MenuBuilder#findItem(int) throwing IndexOutOfBoundsExceptions when the item was not found.
• Fix: Theme attributes for home item data (e.g., icon, logo) will not be overwritten by the special MenuItem instance for home.
• Fix: Native strings can now be specified for an XML menu <item> in android:title and android:titleCondensed.
• Window.FEATURE_ENABLE_ACTION_BAR_WATSON_TEXT is now Window.FEATURE_ACTION_BAR_ITEM_TEXT.
• Widget.Sherlock.Spinner.DropDown.ActionBar and Widget.Sherlock.Light.Spinner.DropDown.ActionBar styles are now Widget.Sherlock.Spinner and Widget.Sherlock.Light.Spinner, respectively.
• Widget.Sherlock.ActionBarView_TabXXX styles are now Widget.Sherlock.ActionBar.TabXXX.

This version is a hotfix for incompatibilities introduced with the SDKs for 3.1 r2 and 3.2 r1. Due to unavoidable changes in the underlying SDK, the library must now be compiled against API level 13.

• actionModeStyle and actionModePopupWindowStyle are no longer valid theme attributes.

• Sub-menus for action items are now shown in a list dialog.
• Moved certain classes to the com.actionbarsherlock.internal package which were not meant for public consumption. Despite being given public scope in this new package, these classes should NOT be used under any circumstances as their API can be considered highly volatile and is subject to change often and without warning.

• Fix: onOptionsItemSelected() not being called in fragments if the activity version returns false.
• Fix: onCreateOptionsMenu() not being called in fragments on Android 3.0+.
• New: Enable action item text display on pre-Android 3.0 by calling requestWindowFeature with Window.FEATURE_ENABLE_ACTION_BAR_WATSON_TEXT.
• Fix: setCustomView() no longer automatically enables the custom view on pre-3.0. You must call setDisplayShowCustomEnabled() in order to display the view.

The API has been rewritten to mimic that of the native action bar. As a result, usage now only requires changing a few imports to use the support versions of classes and calling getSupportActionBar(). See the README for more info.

The rewrite necessitated tight interaction with the compatibility library to the point where its sources are now included. You are no longer required to have the standalone .jar file.

Also included is a default custom action bar for use by default on pre-3.0 devices. This custom implementation is based off of Johan Nilsson's Android-ActionBar and the work that I have done on it.

More details are available at http://actionbarsherlock.com

No changes to library code.

• Moved library to the root of the repository.
• Added samples/dependencies.py script to automatically download the needed dependencies for the sample projects.

WARNING: The Android Compatibility Library (v4) is now required.

• Added ActionBarSherlock.Activity, ActionBarSherlock.FragmentActivity, and ActionBarSherlock.ListActivity for extension by implementing activities, the latter of which is deprecated. This affords a much tighter integration and allows for the use of other new features listed below.
• New API method: layout(Fragment) will use the fragment argument as the content to the activity.
• New API method: menu(int) allows for the inflation of menu XMLs from a resource. For the non-native implementation, the XML can be inflated to a custom Menu which can then be applied appropriately to the third-party action bar. Sub-menus are also supported. Third-party action bar handlers should implement ActionBarSherlock.HasMenu for this functionality. This feature requires that activities extend from one of the provided activity base classes.
• New API method: homeAsUp(boolean). This mimics the native method setDisplayHomeAsUpEnalbed on the native action bar. Third-party action bar handlers should implement ActionBarSherlock.HasHomeAsUp for this functionality.
• New API method: useLogo(boolean) will trigger the action bar to hide the application icon/home button and title and show a larger logo representing the application. Third-party action bar handlers should implement ActionBarSherlock.HasLogo for this functionality.
• New API method: listNavigation(SpinnerAdapter, OnNavigationListener). Tells the action bar to use drop-down style navigation with the specified list of items and callback listener. Third-party action bar handlers should implement ActionBarSherlock.HasListNavigation for this functionality.
• Javadocs are now available at jakewharton.github.com/ActionBarSherlock.
• A standalone JAR is now available via the GitHub downloads page or in my personal maven repository as com.jakewharton:android-actionbarsherlock:2.1.0.

• Use Class.forName() for detection of native action bar. This provides compatability all the way back to Android 1.5.
