Most libraries in the Android Support Library suite have some dependency on one or more libraries. For example, nearly all support libraries have a dependency on the support-compat package. In general, you do not need to worry about support library dependencies, because the gradle build tool manages library dependencies for you, by automatically including dependent libraries.
If you want to see what libraries and library dependencies are included in your app, run the following command at the build root of your app development project to get a report of the dependencies for that project, including Android Support Libraries and other libraries:. For more information about adding support libraries to your development project using Gradle, see Support Library Setup.
For more information about working with Gradle, see Configure Your Build. Note that all Android Support Libraries also depend on some base level of the platform, for recent releases, that is Android 4.

Here is a more complete list of ways you can use the support libraries in your app: Backward Compatibility for newer APIs - A large amount of the support libraries provide backward compatibility for newer framework classes and methods.
For example, the Fragment support class provides support for fragments on devices running versions earlier than Android 3. There are two things to it First This is the page that announces recent releases of the support library, and I don't see Improve this answer. Thanks for the help. The first point is right.
After installing it's showing revision That's why this problem has occurred. In Gradle 4. Try this one compile 'com. Dad Dad 1 1 1 bronze badge. Please add more context to your answer to address how your answer solves the problems asked in the question.

Follow the directions for downloading the Support Libraries in Support Library Setup to complete this step. You must take additional steps to include a specific Support Library in your application. See the end of each library section below for important information on how to include the library in your application.
Some packages require a higher API level, as noted below. These libraries include the largest set of APIs compared to the other libraries, including support for application components, user interface features, accessibility, data handling, network connectivity, and programming utilities. For complete, detailed information about the classes and methods provided by the v4 support libraries, see the android. Note: Prior to Support Library revision That library was divided into multiple modules to improve efficiency.
For backwards compatibility, if you list support-v4 in your Gradle script, your app will include all of the v4 modules. However, to reduce app size, we recommend that you just list the specific modules your app needs. Provides compatibility wrappers for a number of framework APIs, such as Context.
Backports portions of the media framework, including MediaBrowser and MediaSession. Adds support for encapsulation of user interface and functionality with fragments , enabling applications to provide layouts that adjust between small and large-screen devices. This module has dependencies on compat , core-utils , core-ui , and media-compat.
Note: The v13 support library provides a FragmentCompat class. The v4 Fragment class is a standalone class that provides bugfixes which were added in later platform versions, whereas the v13 FragmentCompat class provides compatibility shims for the framework implementation of the Fragment class.
Apps that reference more than methods are required to use multidex configurations. These libraries provide specific feature sets and can be included in your application independently from each other.
Note: The appcompat library has migrated into the AndroidX library, which is an Android Jetpack component. See it in use in the Sunflower demo app.
Issue Changes for Design Support Library : Fixed a bug where a hidden bottom sheet would handle touch events.
Issue Fixed an accessibility issue with Snackbar. Issue Fixed a crash on Snackbar swipe. Issue Fixed a bug in ViewPager related to scroll calculation for size changes.
Issue Fixed a bug where ViewPager does not set AccessibilityEvent parameters properly when scrolling. Fixed an issue that caused lag during device rotation when using Drawable. Issue Changes for v7 appcompat library : Reverted dependency on vector assets so that developers using the appcompat library are not forced to use VectorDrawable and its associated build flags. Issue Fixed an issue with propagating configuration values in Resources objects Issue Fixed a compatibility issue where the android.

Changes for VectorDrawableCompat: Fixed a bug where the wrong variable was read for android:tintMode. The system now calls onActivityResult for a nested FragmentActivity. Switch between Material Light and Material Dark Themes based on the time of day or app-specific setting. Changes for v7 mediarouter library : MediaRouteControllerDialog now correctly applies custom app theme colors.
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.
You can use this to add multiple buttons. This method will only succeed if it is given a valid id and the browser session is in the foreground. 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 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. Description fields are now editable: GuidedAction.
Added drop-down lists of sub-actions: GuidedAction. Added the GuidedDatePickerAction widget for DatePicker functionality: The date is selected using year, month, and day columns and has a customizable range.

To make it easier or harder to swipe, override getSwipeEscapeVelocity float defaultValue and modify defaultValue. Issue Changes for v7 preference library: Fixed an issue with ProGuard usage. Issue Changes for v17 Leanback Support library: Fixed a number of internal issues in this library. Fixed a transparent background issue for a FloatingActionButton object on devices running Android 4. It allows you to receive callbacks when the scroll X or Y positions change.
