Android Support Library, revision 18 (July 2013)

Changes for v4 support library: - User interface - Added BidiFormatter [1] for handling text strings that combine right to left and left to right-formatted text. - Modified ViewPager [2] to better handle cases where the pager has a measured width of zero in the initial layout processing. - Modified DrawerLayout [3] and SlidingPaneLayout [4] to not throw exceptions for measurement while the project code is being edited. - Accessibility - Added ExploreByTouchHelper [5] to simplify the implementation of accessibility for custom views. - Fixed a problem with ViewPager [2] incorrectly populating TYPE_VIEW_SCROLLED [6] accessibility events. - Fixed a null pointer exception in ViewPager [2] when populating an accessibility event. - Simplified AccessibilityNodeInfoCompat [7] by changing CharSequence [8] inputs to String [9] objects. - Deprecated an AccessibilityRecordCompat [10] constructor that used an Object [11] as input. - Media - Added TransportMediator [12] helper class to manage media transport control, such as play, pause, skip and other media actions. - Added DisplayManagerCompat [13] for managing display output to one or more device displays. - Other changes - Added WakefulBroadcastReceiver [14] helper class for implementing a common pattern of detecting a device wakeup event and passing work off to a Service [15] while ensuring that the device does not go back to sleep before the handoff is complete. - Added two new APIs, commitContentChanged() [16] and rollbackContentChanged() [17], to AsyncTaskLoader [18] to help deal with background updates for data changes that are subsequently canceled. New v7 appcompat library: - Added ActionBar [19] to allow implementation of the action bar user interface design pattern [20] back to Android 2.1 (API level 7) and higher. Use of this class requires that you implement your activity by extending the new ActionBarActivity [21] class.
