    + Android Support Library, revision 23.2.0 (February + 2016) +

    + +
    +
    +
    + Changes for v4 Support library: +
    + +
    +
      +
    • Added {@code MediaBrowserCompat} for {@link + android.media.browse.MediaBrowser} support, and {@code + MediaBrowserServiceCompat} for {@link + android.service.media.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 {@link + android.support.v4.app.FragmentActivity#onActivityResult onActivityResult()} for a + nested {@link android.support.v4.app.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: {@code + <sdk>/extras/android/support/v7/appcompat/res/values/themes_daynight.xml} +
        • + +
      • {@code AppCompatDelegate.setDefaultNightMode()}: sets the + app’s default mode by passing one of the following constants: +
        • + +
      • +
          +
        • {@code MODE_NIGHT_AUTO} +
          • + +
        • {@code MODE_NIGHT_NO} +
          • + +
        • {@code MODE_NIGHT_YES} +
          • + +
        • {@code MODE_NIGHT_FOLLOW_SYSTEM} +
          • +
        +
        • + +
      • {@code AppCompatDelegate.setLocalNightMode()}: overrides + the night mode setting for the local app component. +
        • + +
      • {@code AppCompatDelegate.getDefaultNightMode()}: returns + the default night mode. +
        • +
      +
      • +
    +
    + +
    + Changes for v7 mediarouter + library: +
    + +
    +
      +
    • {@link android.support.v7.app.MediaRouteControllerDialog} now + correctly applies custom app theme colors. +
      • +
    +
    + +
    + Changes for Design support library: +
    + +
    +
      +
    • Added support for bottom + sheets. An interaction plugin, {@code + BottomSheetBehavior}, allows a child view of a {@link + android.support.design.widget.CoordinatorLayout} to act as + a bottom sheet. The base class, {@code 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. +
      • + +
    • {@code CustomTabsIntent.Builder.addToolBarItem()}: adds an action + button to a custom tab. You can use this to add multiple buttons. +
      • + +
    • {@code 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: +
      • + +
    • +
        +
      • {@code VectorDrawableCompat} +
        • + +
      • {@code AnimatedVectorDrawableCompat} +
        • +
      +
      • + +
    • Adds support for {@link + android.graphics.drawable.VectorDrawable} assets to apps + running on API level 7 or higher. {@link + android.graphics.drawable.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 {@code + VectorDrawableCompat} within an {@link android.widget.ImageButton} or + {@link android.widget.ImageView}, use the {@code app:srcCompat} XML + attribute or {@code setImageResource()} + method. +
      • + +
    • To keep referencing attribute IDs on API level 20 or + lower, add the following {@code appt} flag to your {@code + build,gradle} file: +
      • + +
    • +
        +
      • If you are building with Android Plugin for Gradle 1.5.0 or + lower, add the following to your {@code 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 {@code build.gradle} file: +
        • + +
      • + 
        +android {
+  defaultConfig {
+    vectorDrawables.useSupportLibrary = true
+  }
+}
+
        +
        • +
      +
      • +
    +
    + +
    + Changes for v17 Leanback + Library: +
    + +
    +
      +
    • Added new capabilities to {@link android.support.v17.leanback.app.GuidedStepFragment}, + which is a component that guides users through a decision or series of decisions: +
      • + +
    • +
        +
      • Added button actions to {@link + android.support.v17.leanback.widget.GuidedAction}: +
        • + +
          +
        • {@code GuidedStepFragment.setButtonActions()}: sets a list of + {@link android.support.v17.leanback.widget.GuidedAction} buttons that + the user may select from the Actions view. +
          • +
        + + +
      • Description fields are now editable: +
        • + +
      • +
          +
        • {@code GuidedAction.Builder.descriptionEditable()}: when passing + {@code true}, sets the action’s description to be editable. +
          • + +
        • {@code GuidedAction.getEditDescription()}: returns the editable + description as a {@code CharSequence}. +
          • +
        +
        • + +
      • Added drop-down lists of sub-actions: +
        • + +
      • +
          +
        • {@code GuidedAction.setSubActions()}: sets a {@link + android.support.v17.leanback.widget.GuidedAction} list as a drop-down + menu of sub-actions. +
          • +
        +
        • +
      + +
    • Added the {@code GuidedDatePickerAction} widget for {@link + android.widget.DatePicker} functionality: +
      • + +
    • +
        +
      • The date is selected using year, month, and day columns and has a + customizable range. +
        • + +
      • {@code GuidedDatePickerAction.Builder}: builder class for the {@code + GuidedDatePickerAction} object. +
        • + +
      • {@code GuidedDatePickerAction.Builder.datePickerFormat(String + datePickerFormat)}: set the desired date format by passing the + appropriate three-character {@code String}, e.g. {@code “YMD”} or {@code + “MDY”}. Alternatively, use the {@code datePickerFormat} XML attribute. +
        • +
      +
      • +
    +
    +
    + +
    +
    + Changes for v7 RecyclerView + library: +
    + +
    +
      +
    • {@link android.support.v7.widget.RecyclerView} now has an opt-in + feature called AutoMeasure which allows {@link + android.support.v7.widget.RecyclerView.LayoutManager} to easily wrap + content or handle various measurement specifications provided by the + parent of the {@link android.support.v7.widget.RecyclerView}. It + supports all existing animation capabilities of the {@link + android.support.v7.widget.RecyclerView}. +
      • + +
    • +
        +
      • If you have a custom {@link + android.support.v7.widget.RecyclerView.LayoutManager}, + call {@code setAutoMeasureEnabled(true)} to start using the new + AutoMeasure API. All built-in {@link + android.support.v7.widget.RecyclerView.LayoutManager} objects + enable auto-measure by default. +
        • + +
      • {@link android.support.v7.widget.RecyclerView.LayoutManager} + no longer ignores some {@link + android.support.v7.widget.RecyclerView.LayoutParams} settings, + such as {@code MATCH_PARENT} in the scroll direction. +

        + Note: These lifted restrictions may cause + unexpected behavior in your layouts. Make sure you specify + the correct layout parameters. +

        +
        • +
      +
      • + +
    • When updating a {@link + android.support.v7.widget.RecyclerView.ViewHolder} with payload + information, {@link android.support.v7.widget.DefaultItemAnimator} + now disables change animations. +
      • + +
    • You can now modify the {@link + android.support.v7.widget.helper.ItemTouchHelper} escape velocity to + control swipe sensitivity. To make it easier or harder to swipe, + override {@code getSwipeEscapeVelocity(float defaultValue)} and modify {@code defaultValue}. +
      • +
    +
    +
    +
    +
    + + +
    +

    + Android Support 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 + {@code ItemTouchHelper} utility class provides, and then add an item. + (Issue 190500)
      • +
    +
    +
    Changes for v7 preference library:
    +
    + +
    + +

      • +
    +
    +
    + +
    +
    + + + +
    +

    + Android Support Library, 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:
    +
