Revision 24.2.1

September 2016

Fixed issues:

A complete list of public bug fixes is available on the AOSP Issue Tracker.

Revision 24.2.0

August 2016

Release 24.2.0 contains the following changes:

Note: Release 24.2.0 removes support for Android 2.2 (API level 8) and lower. Classes and methods that exist only to serve those system versions are now marked as deprecated and should no longer be used. These deprecated classes and methods may be removed in a future release.

v4 Support Library split

With this release, the v4 Support Library has been split into several smaller modules:

support-compat
Provides compatibility wrappers for new framework APIs, such as Context.getDrawable() and View.performAccessibilityAction().
support-core-utils
Provides a number of utility classes, such as AsyncTaskLoader and PermissionChecker.
support-core-ui
Implements a variety of UI-related components, such as ViewPager, NestedScrollView, and ExploreByTouchHelper.
support-media-compat
Backports portions of the media framework, including MediaBrowser and MediaSession.
support-fragment
Backports the fragment framework. This module has dependencies on support-compat, support-core-utils, support-core-ui, and support-media-compat.

For backwards compatibility, if you list support-v4 in your Gradle script, your APK will include all of these modules. However, to reduce APK size, we recommend that you just list the specific modules your app needs.

API updates

Behavior changes

MediaRouter library

Bluetooth devices are no longer listed as media routes. Routing audio to Bluetooth devices is now solely controlled at the Android system level.

Deprecations

Deprecated classes and methods are subject to removal in a future release. You should migrate away from these APIs as soon as possible.

Revision 23.2.0

February 2016

Changes for v4 Support library:
  • Added MediaBrowserCompat for MediaBrowser support, and MediaBrowserServiceCompat for MediaBrowserService support. This is useful when connecting a media app’s background service with UI components, and integrating with Android Auto and Android Wear without requiring API level 21 or higher.
  • The system now calls onActivityResult() for a nested FragmentActivity.
Changes for v7 AppCompat library:
  • Added Night Mode functionality to API level 14 and higher. Switch between Material Light and Material Dark Themes based on the time of day or app-specific setting.
    • Day and night themes can be found here: <sdk>/extras/android/support/v7/appcompat/res/values/themes_daynight.xml
    • AppCompatDelegate.setDefaultNightMode(): sets the app’s default mode by passing one of the following constants:
      • MODE_NIGHT_AUTO
      • MODE_NIGHT_NO
      • MODE_NIGHT_YES
      • MODE_NIGHT_FOLLOW_SYSTEM
    • AppCompatDelegate.setLocalNightMode(): overrides the night mode setting for the local app component.
    • AppCompatDelegate.getDefaultNightMode(): returns the default night mode.
Changes for v7 mediarouter library:
Changes for Design support library:
  • Added support for bottom sheets. An interaction plugin, BottomSheetBehavior, allows a child view of a CoordinatorLayout to act as a bottom sheet. The base class, BottomSheetCallback, provides callbacks to monitor bottom sheet events.
Changes for the CustomTabs support library:
  • Chrome Custom Tabs now allows apps to include a bottom bar with action buttons in addition to the existing top action button.
  • CustomTabsIntent.Builder.addToolBarItem(): adds an action button to a custom tab. You can use this to add multiple buttons.
  • CustomTabsSession.setToolBarItem(): updates the visuals for toolbar items. This method will only succeed if it is given a valid id and the browser session is in the foreground.
Added VectorDrawable support library:
  • Added Classes:
    • VectorDrawableCompat
    • AnimatedVectorDrawableCompat
  • Adds support for VectorDrawable assets to apps running on API level 7 or higher. AnimatedVectorDrawable assets are also supported on API level 11 or higher. Vector assets can be considerably smaller than image assets and should help reduce app size by reducing the amount of assets required to support multiple device screens.
  • This library is now a dependency of the v7 AppCompat library, allowing developers and AppCompat to easily use vector drawables. To use VectorDrawableCompat within an ImageButton or ImageView, use the app:srcCompat XML attribute or setImageResource() method.
  • To keep referencing attribute IDs on API level 20 or lower, add the following appt flag to your build,gradle file:
    • If you are building with Android Plugin for Gradle 1.5.0 or lower, add the following to your build.gradle file:
    • android {
        defaultConfig {
          // Stops the Gradle’s automatic rasterization of vectors
          generatedDensities = []
        }
         // Flag that tells aapt to keep the attribute ids
        aaptOptions {
          additionalParameters "--no-version-vectors"
        }
      }
      
    • If you are building with Android Plugin for Gradle 2.0.0 or higher, add the following to your build.gradle file:
    • android {
        defaultConfig {
          vectorDrawables.useSupportLibrary = true
        }
      }
      
Changes for v17 Leanback Library:
  • Added new capabilities to GuidedStepFragment, which is a component that guides users through a decision or series of decisions:
    • Added button actions to GuidedAction:
      • GuidedStepFragment.setButtonActions(): sets a list of GuidedAction buttons that the user may select from the Actions view.
    • Description fields are now editable:
      • GuidedAction.Builder.descriptionEditable(): when passing true, sets the action’s description to be editable.
      • GuidedAction.getEditDescription(): returns the editable description as a CharSequence.
    • Added drop-down lists of sub-actions:
      • GuidedAction.setSubActions(): sets a GuidedAction list as a drop-down menu of sub-actions.
  • Added the GuidedDatePickerAction widget for DatePicker functionality:
    • The date is selected using year, month, and day columns and has a customizable range.
    • GuidedDatePickerAction.Builder: builder class for the GuidedDatePickerAction object.
    • GuidedDatePickerAction.Builder.datePickerFormat(String datePickerFormat): set the desired date format by passing the appropriate three-character String, e.g. “YMD” or “MDY”. Alternatively, use the datePickerFormat XML attribute.
Changes for v7 RecyclerView library:

Revision 23.1.1

November 2015

Changes for v7 recyclerview library:
  • Fixed a crash that occurs when you perform a swipe-to-dismiss action that the ItemTouchHelper utility class provides, and then add an item. (Issue 190500)
Changes for v7 preference library:
Changes for v17 Leanback Support library:
  • Fixed a number of internal issues in this library.
Changes for Design Support library:
  • Added the getHeaderView method to the NavigationView class.
  • Fixed a transparent background issue for a FloatingActionButton object on devices running Android 4.0 (API level 15) and lower. (Issue 183315)

Revision 23.1.0

October 2015

Changes for v4 Support library:
  • Added OnScrollChangedListener interface support to the NestedScrollView widget. It allows you to receive callbacks when the scroll X or Y positions change.
  • Added a MediaButtonReceiver class to forward received playback controls to a service that’s managing the MediaSessionCompat class. The MediaSessionCompat class has a constructor that can automatically find a media button receiver in the manifest. A media button receiver is a key part to handling playback controls from hardware or bluetooth controls.
Changes for v7 appcompat library:
  • Added material design Seekbar and ImageButton widgets.
  • Updated the ImageView widget to support the tint feature.
  • Updated the look-and-feel of the SwitchCompat widget.
Changes for v7 mediarouter library:
  • Added the following features to the MediaRouteChooserDialog class:
    • Displays a loading page while discovering media route providers.
    • Includes a device type icon for easier device identification.
    • Sorts the routes according to frequency of use in the current app.
    • Supports landscape mode.
  • Added the following features to the MediaRouteControllerDialog class:
    • Recognizes screen casting and provides a proper description.
    • Supports various album art sizes and aspect ratios, and loads the art asynchronously.
    • Automatically selects the content color based on the primary color of the app.
    • Adjusts the dialog layout based on available screen space on the device.
    • Supports landscape mode.
Changes for v7 palette library:
  • Added the setRegion() method to support extracting color from a specific region of a Bitmap object.
Changes for v7 recyclerview library:
  • Added an improved animation API to the ItemAnimator class for better customizations:
    • Change animations no longer enforce two copies of the ViewHolder object, which enables item content animations. Also, the ItemAnimator object decides whether it wants to reuse the same ViewHolder object or create a new one.
    • The new information record API gives the ItemAnimator class the flexibility to collect data at the correct point in the layout lifecycle. This information is later passed into the animate callbacks.
  • Provided an easy transition plan for this backward-incompatible API change:
    • If you’ve previously extended the ItemAnimator class, you can change your base class to SimpleItemAnimator and your code should work as before. The SimpleItemAnimator class provides the old API by wrapping the new API.
    • Some methods were removed from the ItemAnimator class. The following code will no longer compile:
    • recyclerView.getItemAnimator().setSupportsChangeAnimations(false)

      You can replace it with:

      ItemAnimator animator = recyclerView.getItemAnimator();
      if (animator instanceof SimpleItemAnimator) {
         ((SimpleItemAnimator) animator).setSupportsChangeAnimations(false);
      }
                 
Changes for v7, v14, and v17 Preference Support library:
  • Removed APIs for controlling EditText dialogs.
Changes for v17 Leanback Support library:
  • Added a version of the GuidedStepFragment class for the Support library (extends android.support.v4.app.Fragment), and improved animations and transitions.
  • Updated the GuidedStepFragment class so it can be placed on top of existing content.
  • Added the ability to annotate different types of search completions to the SearchFragment class.
  • Added staggered slide transition support to the VerticalGridFragment class.
Changes for Design Support library:
  • Added character counting support to the TextInputLayout widget.
  • Added edge snapping support to the AppBarLayout class by adding the SCROLL_FLAG_SNAP constant. When scrolling ends, if the view is only partially visible, the view is snapped and scrolled to its closest edge.
  • Added support for custom views to the NavigationView class by using the app:actionLayout attribute or MenuItemCompat.setActionView() method.
Changes for Custom Tabs Support library:
  • Added the enableUrlBarHiding() method to the CustomTabsIntent class. It lets the client customize whether the URL bar should be hidden automatically on scroll down.
  • Added the setActionButton() method to the CustomTabsSession class. It lets the client change the icon for a custom action button in an already launched custom tab.
  • Added the TAB_SHOWN and TAB_HIDDEN constants as new events for the onNavigationEvent method of the CustomTabsCallback class.

Revision 23.0.1

September 2015

Changes for v7 and v14 Preference Support library:
  • Added the material design layout and style files. (Issue 183376)
Changes for v7 appcompat library:
  • Fixed crash issues for the Fragment class by limiting the use of hardware layers to Android 4.1 (API level 16) and higher. (Issue 183896)
  • Fixed an issue where hardware buttons did not work when an activity had set the Toolbar class to act as the ActionBar by using the setSupportActionBar() method. (Issue 183334)
  • Updated the AppCompatDialogFragment class so it no longer throws the Windows feature must be requested before adding content error. (Issue 183186)

Revision 22.2.0

May 2015

Added Design Support library:
  • Added TextInputLayout for showing EditText hint and error text as floating labels.
  • Added FloatingActionButton for implementing a primary action on your interface as a floating action button, supporting either default or mini sizes.
  • Added Snackbar for providing lightweight feedback with an optional action in an animated snackbar.
  • Added TabLayout for implementing fixed and scrollable tabs as well as easy integration with ViewPager.
  • Added NavigationView for implementing navigation drawer contents, including the ability to inflate menu items via a Menu Resource.
  • Added CoordinatorLayout, a general purpose layout, used for building dependencies between sibling views and allowing easy scrolling reactions between components via CoordinatorLayout.Behavior. Many of the Design Library components rely on being a child of a CoordinatorLayout.
  • Added AppBarLayout, a container for a Toolbar and other views (such as TabLayout) for reacting to scrolling events by scrolling off the screen, becoming visible in reaction to a downward scroll, or collapsing/uncollapsing before scrolling off/onto the screen.
  • Added CollapsingToolbarLayout for controlling how a Toolbar collapses. A toolbar may collapse by: pinning components to the top of the screen while it collapses, introducing parallax scrolling of components such as an ImageView, or adding a content scrim color when the view is partially collapsed.

October 2014

Changes for v4 support library:
  • Added support for Fragment transitions for devices running Android 5.0 (API level 21). Be aware that transitions have no effect on devices running Android 4.4 and lower.
  • Added DocumentFile to ease the transition from File while working with document trees. However, this class demands more processing overhead compared to the platform's DocumentsContract API added in Android 4.4 (API level 19). So you should switch to using DocumentsContract when running on Android 4.4 and higher.

  • Added explicit start, get, and end session actions for explicitly managing media playback sessions with media router.

Revision 18

July 2013

Changes for v4 support library:
New v7 appcompat library:
  • Added ActionBar to allow implementation of the action bar user interface design pattern 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 class.
New v7 mediarouter library:

Added a new mediarouter library that provides support for the Google Cast developer preview. The v7 mediarouter library APIs provide a means of controlling the routing of media channels and streams from the current device to external screens, speakers, and other destination devices, with compatibility back to Android 2.1 (API level 7). See V7 mediarouter library for more information.

The v7 mediarouter library APIs introduced in Support Library r18 are subject to change in later revisions of the Support Library. At this time, we recommend using the library only in connection with the Google Cast developer preview.

Revision 13

May 2013

Changes for v4 support library:
New v7 gridlayout library:
  • Added GridLayout to provide support for the GridLayout layout object.
  • Added android.support.v7.widget.Space which can be used to create blank areas within a GridLayout layout object.

  • Added .classpath and .project files for the gridlayout library project.

Revision 7

March 2012

Changes for v4 support library:
  • Added ShareCompat, which provides helper classes for sending and receiving content for social sharing applications, including new metadata for attributing shared data to the source app. This class also provides compatible integration with the new ShareActionProvider in Android 4.0.
  • Added NavUtils and TaskStackBuilder to provide support for implementing the Android Design guidelines for navigation. These additions include a way to implement the action bar's Up button across versions. For an example implementation of this pattern, see the AppNavigation sample in (<em><sdk></em>/samples/<em><platform></em>/AppNavigation).
  • Added NotificationCompat.Builder to provide a compatibility implementation of Android 3.0's Notification.Builder helper class for creating standardized system notifications.

Revision 6

December 2011

Note: Reference for support library APIs are now available with the framework references, for example: android.support.v4.app.

Changes for v4 support library:
  • Changes to ViewPager:
    • Added extra decorative view support for ViewPager. Decorative views may be supplied as child views of a pager in XML layout.
    • Added PagerAdapter.getPageTitle() to supply title strings for pages, which defaults to no title for each page.
    • Added PagerTitleStrip, a non-interactive title strip, that can be added as a child of ViewPager. Developers can supply text appearance and color, as well as layout sizing and gravity information.
    • Updated PagerAdapter methods to take ViewGroup objects, rather than View to avoid class casting in adapter implementations.
    • Updated ViewPager to use Launcher-style fling behavior.
    • Bug fixes for user interface interaction and test automation.
  • Support for Fragments:

Revision 5

December 2011

Changes for v4 support library:

Revision 4

October 2011

Changes for v4 support library:
  • Added EdgeEffectCompat to support EdgeEffect.
  • Added LocalBroadcastManager to allow applications to easily register for and receive intents within a single application without broadcasting them globally.
  • Added support in ViewCompat to check for and set overscroll modes for Views on Android 2.3 and later.
  • Changes to Fragment APIs:
    • Added new APIs to control the visibility of new menus.
    • Added custom animation APIs.
    • Added APIs in FragmentActivity to retain custom, non-configuration instance data.
    • Various bug fixes.
  • Fixed a Loader bug that caused issues in canceling AsyncTasks when running on Froyo and older versions of the platform. The support code now uses its own version of AsyncTask to keep the same behavior on all platform versions.

Revision 3

July 2011

Changes for v4 support library:
  • Adds support for Fragment.SavedState
  • Adds MotionEventCompat to support newer MotionEvent APIs
  • Adds VelocityTrackerCompat to support a newer VelocityTracker APIs
  • Adds ViewConfigurationCompat to support a newer ViewConfiguration APIs
  • All new APIs (available only in the support library) that allow you to create UIs with horizontal paging, allowing users to swipe left and right between content views. Classes to support this include:
    • ViewPager: A ViewGroup that manages the layout for the child views, which the user can swipe between.
    • PagerAdapter: An adapter that populates the ViewPager with the views that represent each page.
    • FragmentPagerAdapter: An extension of PagerAdapter for flipping between fragments.
    • FragmentStatePagerAdapter: An extension of PagerAdapter for flipping between fragments that uses the library's support for Fragment.SavedState.
New v13 support library:
  • Includes the FragmentPagerAdapter and FragmentStatePagerAdapter to support the horizontal paging.

    These are exactly the same as the APIs added to the v4 support library, but rely on other platform components in Android 3.2. Use this library instead of v4 if you're developing for Android 3.2 and higher (all other APIs in the v4 library are already available with API level 13).
