Provides compatibility wrappers for a number of framework APIs, such as Context. However, to reduce app size, we recommend that you just list the specific modules your app needs. For backwards compatibility, if you list support-v4 in your Gradle script, your app will include all of the v4 modules. Note: Prior to Support Library revision That library was divided into multiple modules to improve efficiency. For complete, detailed information about the classes and methods provided supporh the v4 support libraries, see the android. 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. Some packages require a higher API level, as noted below. See the end of each library section below for important information on how to include the library in your application.
